Description And Manual For Talking MultiMeter

Headings have been added to facilitate navigation.

Description

The following description is provided by a MultiMeter owner.

This morning I had the opportunity to sit down with two of our plant engineers and my newly acquired talking multimeter. Some of the instructions in the manual were not obvious to me but soon explained. Remember too that I am not an electronics expert so some of the functions are not clear to me. There is one function none of us worked out, something labelled "REL". It is mentioned but the manufacturer assumes that I am not so much of an idiot as to need this function explained.

The multimeter is not exactly as described in the manual but very similar. It comes with removable test leads, the manual reports them as attached.

In the box is the main body of the meter, two test leads with pointed caps over the pointed probes and caps inserted into the bayonet like fittings which insert into sockets on the front of the body of the meter. There is also a nylon carry wallet and the manual.

The body of the meter is about 6 inches high, three and a half wide and about two inches thick, actual specifications will be with the manual further down when I get there. The lower end is bevelled for about three quarters of an inch on the face surface and partially rounded at the bottom end of the edges. There is a rubberized boarder wrapping the entire outer edge of the meter giving it both protection and a easily and securely gripped surface.

The rear panel has two screws at the lower edge probably for disassembly, a flip out support leg, something like often found on the back of picture frames to hold them up on a slight angle. I do not find this satisfactory but I suppose optically enabled people would be happy enough to hold it more easily visible.

About the top third of the rear panel has a plastic battery cover. To remove this, a screw is released from the lower edge of this cover, located between the two upper hinges of the support stand. There is a slot at the top of the cover to pry it off with. It is a little tight. It gives access to the bay for three double 'A' batteries.

Of more interest is the front panel. The top quarter contains the LCD display. This display reveals the meter numbers but some other characters such as "OL" when the meter is reading out of range, "overload". There are some other symbols to indicate modes. The LCD display can be back lit for better viewing clarity or low light conditions.

The lower mounting for the meter is rounded, a little like a smile I suppose with three buttons quite flush mounted around this curve. The left most of these buttons is labelled "HOLD", the second or middle button "FUNCTION" and the right most button is "REL". So far we do not know what is meant by "REL". It seems to have something to do with calibrating capacitor readings.
Below these three buttons are two round and textured buttons. The left most is the "LOC" button which turns on the back light. If you press it in and rotate it, the light is locked on.
The right button of this pair is the "TALK" button. Press it and the display is spoken. Press and rotate it and continuous talking is enabled where the reading is continuously repeated at about two second intervals until this feature is disabled.

Below the buttons there is a rotary select dial, about two inches in diameter. It is recessed in the centre with a bar to grasp to turn for selection of the various options.
On my model the bar is set horizontally when the switch is to the far left or counter clockwise position, the off position. It rotates through 7 positions to the fully clockwise position again horizontally and again off.

Below this dial and in the corners left vacant because the dial is round are the sockets for the probe wires. The left one is the black, the right is the active lead. The cables push in with the wires coming off at 90 degrees. The active probe differs from the other one in that there is a small button on it which will, if pressed and released within about a second and a half will cause the meter reading displayed to be spoken. If held longer it causes the light to come on for 30 seconds. The tips of the probes are also lit for sighted people to locate them I suppose.

The functions selected by the rotary dial beginning from the left most off position are:
DC voltage *
AC voltage
RESISTANCE *
CAPACITANCE
FREQUENCY
AMPERAGE *
NOTE: * indicates multiple function.

* "DC" mode: Pressing the "FUNCTION" key here will toggle to reading an AC voltage over a DC carrier.
* The "RESISTANCE" mode position has three functions selected by pressing the "FUNCTION" button. This switches between "RESISTANCE", "DIODE" and "CONTINUITY" modes. A loud beep is heard as the modes change. In the CONTINUITY mode, a continuous tone is generated when a circuit is in tact.
*"AMPERAGE" or current: The "FUNCTION" key toggles between AC and DC. Otherwise, the range selection is all automatic. You are warned not to exceed 1000 volts DC or 750 volts AC. I cannot speak to the accuracy of this meter except to say that it is very consistently reading 60 Hz frequency when I attach it to the wall circuit. The engineers at work thought they might buy one for the Hospital for calibrating our emergency generator. Apparently dedicated frequency meters cost around three hundred dollars. One thought he would buy one just to listen to a clear intelligent female voice since his wife doesn't talk to him any more.

It should be noted that reference to 500 volts is made in the manual as is reference to selecting measurement ranges however this latter requirement must apply to an earlier version of the meter as there is no way to select ranges.

Below I will insert the manual as I scanned it last week with K1000. I hope this helps satisfy some of your curiosity. For 40 bucks Canadian this is a pretty good deal in my view and the device appears to me to be well made and executed.

Installing the battery

Your meter requires 3 AA batteries (not included).

To avoid electrical shock, disconnect both of the meter's test leads from any equipment before you install or remove the meter's battery.
. Do not operate your meter until the battery is properly installed and the battery compartment cover is in place and secured.
Caution: Use only a fresh battery of the required size and recommended type.

1. Set the selector to OFF.
2. Use a Phillips screwdriver to loosen the screws in the battery compartment cover, then lift off the cover
3. Place the battery in the compartment as indicated by the polarity symbols (+ and -) marked inside.
4. Replace the cover and secure it with the screws.

When 3 appears on the display, the display dims, or the meter does not seem to measure accurately, replace the battery. If the battery power is extremely low, ["*+! does not display.
Warning: Dispose of old batteries promptly and properly. Do not bury or burn them.
Caution: Always remove an old or weak battery. Batteries can leak chemicals that can destroy electronic parts. If you are not going to use the meter for a few weeks, remove the battery.

USING THE METER

Caution: Do not try to measure voltage greater than 1000V DC/ 750V RMS AC. To use the meter, open the meter's case by pulling the tabs on the case in opposite directions. Then unwind the test leads from inside the cover. Caution: The test leads are permanently attached to the meter. Do not try to remove them. Rotate the selector to the function you want to use. Then connect the test leads to the circuit you want to measure. See the unit of measure on the front of the meter to distinguish the range. For example, DC V includes we ranges; 400 my, 4V, 40, 400 and 1000. Caution: If OL appears when you are measuring voltage, the value you are measuring exceeds the meter's maximum range. Immediately disconnect the probes from the circuit or your meter might be damaged. Also, note the position of the decimal. When you
1. Set the selector to OFF .
2. Put in carrying case.
3. Tuck the test leads inside the carrying case and close the cover.

Making measurements Measuring DC/AC Voltage

Warning: The maximum input limit for voltage measurement is 1000V DC and 750V AC (RMS). To avoid electrical shock and damage to the meter, never try to measure a DC voltage above 1000 volts or an AC voltage above 750 volts RMS. Follow these steps to measure DC or AC voltage:

1. Set the selector to DC V to measure DC voltage or set AC V to measure AC voltage.
2. Connect the test leads to the circuit you want to test.
3. If you cannot determine the correct position, set the range switch to the highest range for the type of voltage (AC or DC) you are measuring, then reduce it as necessary until the correct range is reached.
When you want the meter to announce the test result, press the switch on the red test lead for less than 1.5 seconds. If you want the meter to be alluminated press the switch on the red test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Measuring AC Voltage Riding on a DC Source Bias

To measure an AC voltage superimposed on a DC voltage source bias, you must first measure the DC and AC voltages separately, then compute the peak voltage using this formula:
^--^9*+T
Warning: To avoid injury to yourself or damage to your meter, never try to measure an AC voltage that is riding on a DC source bias where the peak voltage exceeds 500 V with respect to earth ground.
Caution: Never try to measure any voltage more than 30V AC on a DC source bias. Follow these steps to measure AC voltage:

1. Set the selector to DC V.
2. Connect the test leads to the circuit you want to test. The display shows the DC voltage.
3. Disconnect the test leads from the circuit.
4. Set the selector to AC V.
5. Connect the meter's test leads again to the same circuit you tested in Step 2. The display shows the AC voltage.
6. To compute the peak voltage, refer to the formula seen above.

Measuring resistance

The resistance measuring circuit in your meter compares the voltage gained through a known internal resistance with the voltage developed across an unknown resistance.
Warning: Be sure the circuit under testing has all power removed and any associated capacitors are fully discharged before you make a resistance measurement.

1. Set the selector to OHM/DIODE/CONTINUE.

Caution: Your meter has a circuit to protect the resistance range from over-voltage. However, to prevent accidentally exceeding the protection circuit's rating and to ensure a correct measurement, never connect the test leads to a source of voltage while the selector is set to OHM/DIODE/CONTINUE.
Note:
1. If there is no resistance connected across the test leads or the measured value exceeds the range you set, OL appears when you set the selector to OHM.
This is normal.

2. Connect the test leads across the circuit you want to measure. Or, remove one of the component's leads you want to measure from its circuit and connect the test leads across the component. The meter displays the reading in the chosen range.

3. If you want the meter to announce the test result, press the switch on the red test lead for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Checking diodes

This measurement lets you check diodes, transistors, and other semiconductors for opens, shorts, and normal operation. It also lets you determine the forward voltage for diodes. (This is handy when you need to match a diode).
Caution: Do not connect the test leads to a source of voltage when you set the selector to Diode. This could damage the meter or circuit being tested.

to change the meter to the diode function.

2. Remove power from the circuit under test.

3. Connect the test leads across the circuit you want to measure, or remove one of the component's leads you want to measure from its circuit and connect the test leads across the component. Then note the reading.

4. Reverse the test leads and note the second reading.

In a circuit, a good diode should till forward-bias reading of 0.5V to 0.8V; however, the reverse-bias reading can vary depending on the resistance of other pathways between the probe tips.
Note:
1. The values that appear during the diode check show the actual forward voltage (max. 1.5V).

2. If you want the meter to announce the test result, press the switch on the red test lead for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Continuity Sound Test

Position the selector switch on the OHM/DIODE/CONTINUE and press the "FUNCTION "key to change the meter to the continuity function. Audible beep when R<35 ohm.

Cap Test

Position the selector switch on the "CAP" function. Press the "REL" key to make the meter "zero".
Automatic range selection: Read the measured value. The capacitance should be discharged before the test. Hold, if necessary, by pressing the "HOLD" key.
If you want the meter to announce the test result, press the switch on the red test lead for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Frequency Measurement

Position the selector switch on the "Hz" function.
Automatic range selection: Read the measured value. Hold, if necessary, by pressing the "HOLD" key. If you want the meter to announce the test result, press the switch on the red test lead for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.
Note: Because of high sensitivity in this function, the meter will catch a signal and will display the number with the test-leads open.

Maintenance Care

Your LCD Digital Multimeter is an example of superior design and craftsmanship. The following suggestions will help you care for the meter so you can enjoy it for years.

Keep the meter dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits.
. Use and store the meter only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.
. Handle the meter gently and carefully. Dropping it can damage the circuit boards and case and can cause the meter to work improperly.
. Use only fresh batteries of the required size and type. Always remove old or weak batteries. They can leak chemicals that destroy electronic circuits.

Modifying or tampering with the internal components can cause malfunction and may invalidate the waranty.

Cleaning

To keep the meter looking new, occasionally wipe it with a cloth slightly dampened with water. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the meter.

Warnings:

. Do not let any water drip inside the meter while cleaning it.
. Make sure that the meter is completely dry before using it.
