Nearly every electrical engineer has a hand held

Multimeter. We sometimes take them for granted, until

we damage them or “burn them out” if you incorrectly

connect your DMM to a circuit or 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 20A.

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 :

!Before 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.

!Inspect 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.

!Do not apply more than the rated voltage, as

marked on the Meter, between the terminals or

between any terminal and grounding.

!The 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.

!When measurement is taken at an effective voltage

over 60V in DC or 30V rms in AC, special care

should be takenforthereisdanger of electric shock.

!Use the proper terminals, function, and range for

your measurements.

!Do not use or store the Meter in an environment of

high tempe r ature, humid i ty, e x plosiv e,

inflammable and strong magnetic field. The

performance of the Meter may deteriorate after

the meter is dampened.

!When using the test leads, keep your fingers

behind the finger guards.

Rules For Safe Operation (2)

!Disconnect circuit power and discharge all high

-voltage capacitors before testing resistance,

continuity, diodes, current or capacitance.

!Replace 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.

!Turn the Meter power off when it is not in use and

take out the battery when not using for a long

time.

!Constantly 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.

MEASUREMENT OPERATION

nMake sure the Low Battery display is not on,

otherwise false readings may be provided.

nPay extra attention to the symbol which is located

besides the input terminals of the Meter before carrying

out measurement.

A. DC voltage measurement (see figure 3)

Warning

To avoid harms to you or damages to the Meter from

electric shock, please do not attempt to measure

voltages higher than 1000VDC or 700V rms although

readings may be obtained.

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.

Caution :

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.

Warning :

To avoid harm to you or damages to the Meter

from electric shock, please do not attempt to

measure voltages higher than 1000V or 700V rms

although readings may be obtained.

The AC Voltage measurement has 4 measurement

positions on the rotary switch : 2V, 20V, 200V and

700V

To measure AC Voltage, connect the Meter as

follows :

1) Insert the red test lead into the VWterminal

and the black test lead into the COM 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,

which is effective value of sine wave (mean value

response).

Caution :

nIf the value of voltage to be measured is

unknown, use the maximum measurement

position (700V) 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.

nWhen AC Voltage measurement has been

completed, disconnect the connection between

the testing leads and the circuit under test.

C. AC Current Measurement (see figure 5)

Warning :

Never attempt an in - circuit current measurement

where the open circuit voltage between terminals and

ground is greater than 60V DC or 30V rms. If the fuse

burns out during measurement, the Meter may be

damaged or the operator himself may be hurt. Use

proper terminals, function, and range for the

measurement. When the testing leads are connected

to the current terminals, do not parallel them across

any circuit.

The AC current measurement has 4 measurement

positions on the rotary switch : 2mA, 20mA, 200mA,

20A.

To measure AC Current, connect the meter as

follows :
