DIGITAL

MULTIMETER

405

Nearly every electrical engineer has a hand held

digital multimeter (DMM). We sometimes take them

for granted, until we damage them or “burn them out”

if you incorrectly connect your DMM to a circuit, or if

you have the DMM on wrong setting, you damage the

meter and possibly hurt yourself. You can also get into

trouble if you try to measure the voltage across a

charged capacitor.

DMM users frequently burn their meters by trying

to measure current the same way as they measure

voltage, Remember, you measure voltage across a

circuit, and current through a circuit. When you use

the current input, your DMM becomes a lower

impedance circuit element. If you accidentally

connect this low impedance path across your circuit,

you’ll effectively short-circuit it. You can, therefore

send high current through your meter and severely

damage it. Unless the meter has a fused input, you

can even get an explosion or fire.

Even if you correctly insert your DMM into the

circuit, you can still damage your meter. Don’t try to

measure current in excess of your meter’s capacity.

Handheld DMMs usually have a maximum current

rating of 10Aor 20A.

If you are measuring current in industrial

environment, you can easily exceed those ratings.

The best way to avoid damage is to use a clamp

meter or to connect a clamp attachment to your DMM.

To prevent excess current from flowing through

your meter, always disconnect the test leads from the

circuit under test whenever you change DMM

functions, Set your meter to the correct function, say

current and its highest range for the setting, say 10A.

Next, connect the test leads before you apply power

to the circuit. To be safe, start by setting your meter to

its highest range first.

TAKE MEASUREMENT CAREFULLY AND YOU’LL

SPARE YOUR METER AND YOURSELF, SOME PAIN

Rules For Safe Operation (1)

Warning

To avoid possible electric shock or personal

injury, and to avoid possible damage to the

Meter or to the equipment under test, adhere to

the following rules :

nBefore using the Meter inspect the case. Do not

use the Meter if it is damaged or the case (or

part of the case) is removed. Look for cracks or

missing plastic. Pay attention to the insulation

around the connectors.

nInspect the test leads for damaged insulation or

exposed metal. Check the test leads for

Continuity. Replace damaged test leads with

identical electrical Specifications before using

the Meter.

nDo not apply more than the rated voltage, as

marked on the Meter, between the terminals or

between any terminal and grounding.

nThe rotary switch should be placed in the right

position and no any changeover of range shall

be made while measurement is conducted to

prevent damage of the Meter.

nWhen measurement is taken at an effective

voltage over 60V in DC or 30V rms in AC,

special care should be taken for there is danger

of electric shock.

nUse the proper terminals, function, and range

for your measurements.

nDo not use or store the Meter in an environment

of high temperature, humidity, explosive,

inflammable and strong magnetic field. The

performance of the Meter may deteriorate after

the meter is dampened.

nWhen using the test leads, keep your fingers

behind the finger guards.

nDisconnect circuit power and discharge all high

-voltage capacitors before testing resistance,

continuity, diodes, or current.

nReplace the battery as soon as the battery

indicator appears. With a low battery, the

Meter might produce false readings that can

lead to electric shock and personal injury.

nTurn the Meter power off when it is not in use

and take out the battery when not using for a

long time.

nConstantly check the battery as it may leak when

it has not been used for some time, replace the

battery as soon as leaking appears. A leaking

battery will damage the Meter.

The DC Voltage ranges are :200mV, 2V, 20V, 200V,

1000V.

To measure DC voltage, connect the Meter as

follows :

1) Insert the red test lead into the VWinput terminal

and the black test lead into the COM input

terminal

2) Set the rotary switch to an appropriate

measurement position in V range.

3) Connect the test leads across with the

object being measured.

The measured value is shown on the display.

nIf the value of voltage to be measured is

unknown, use the maximum measurement

position (1000V) and reduce the range step by

step until a satisfactory reading is obtained.

nThe LCD displays “1” indicating the existing

selected range is overloaded, it is required to

select a higher range in order to obtain a correct

reading.

nIn each range, the Meter has an input impedance

of approx. 10MW. This loading effect can cause

measurement errors in high impedance circuits.

If the circuit impedance is less than or equal to

10kW, the error is negligible (0.1% or less).

nWhen DC voltage measurement has been

completed, disconnect the connection between

the testing leads and the circuit under test.
