Switching on

Press any button to switch on the instrument. The instrument starts in continuity testing
mode. Press the "2/200 mA" button to switch to voltage display mode. This button ena-
bles you to switch back and forth between continuity test and voltage display.

Continuity test

The short range of the measuring instrument (0 – 20 Ω) and the fact that it can be influ-
enced by the test lead resistance means that you should first calibrate the measuring in-
strument before starting the continuity test. The calibration removes the influence of the
test lead. You can perform calibration in 2 mA / 200 mA mode.
