Measurement Operation

Part 1 Multimeter Basic Testing

A. AC/DC Voltage Testing (see gure 4)

Warning

To avoid harms to you or damages to the Meter from electric shock, please do

not attempt to measure voltages higher than 1000Vp although readings may be

obtained.

Please take extra care when measuring high voltages to avoid electric shock.

To measure DC voltage, connect the Meter 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 , press BLUE

button to switch between AC and DC measurement mode.

3. AC voltage measurement display true rms value and press Hz button to obtain the

frequency value, input amplitude and frequency response refer to accuracy

specications.

4. Connect the test leads across with the object being measured.

The measured value shows on the display.
