( 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 1000V DC/750V AC although

readings may be obtained.

The DC voltage ranges are: 200.0mV, 2.000V, 20.00V,

200.0V and 1000V.

To measure DC voltage, connect the Meter as follows:

1. Insert the red test lead into the VΩ terminal and

the black test lead into the COM terminal.

2. Set the rotary switch to an appropriate measurement

position in V .

3. Connect the test leads across with the object being

measured.

The measured value shows on the display.

Note

l 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.
