Multimeter Basic Testing

A. AC or DC Voltage Testing

 (see figure 3)

          To avoid harms to you or damages to the

multimetereter from electric shock, please do not 

attempt to measure voltages higher than 1000Vp 

although readings may be obtained.

          Never attempt an in-circuit current

measurement where the open circuit voltage

between terminals and ground is greater than 250V.

If the fuse burns out during measurement, the

multimeter 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.

WARNING

The DC voltage ranges are: 200.0mV, 2.000V,

 20.00V, 200.0V and 1000V.
The AC voltage ranges are: 2.000V, 20.00V,

 200.0V and 750V
To measure DC or AC voltage, connect

the multimeter as follows:
1. Insert the red test lead into the V terminal and

    the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate

    measurement position in V    . or V
3. Connect the test leads across with the object

    being measured. The measured value shows on

    the display.
Note

• If

 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.

• The 

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.

• 

In each range, the multimeter has an input

   impedance of approx. 10M

Ω

. This loading effect

   can cause measurement errors in high impedance

   circuits. If the circuit impedance is less than or

   equal to 10k

Ω

, the error is negligible (0.1% or

   less). When DC voltage measurement has been

   completed, disconnect the connection between

   the testing leads and the circuit under test.
