5.6 Circuit continuity test
WARNING:
Do not perform measurements on the circuit under the volt-
age. Before the measurement disconnect the power and dis-
charge capacitors.
To perform the continuity test:

set the rotary switch at
Ω
CAP
,

connect black test lead to COM terminal, and red test lead to
VΩHz%
mACAP
terminal,

press MODE button, to display on the screen,

contact the tips of test probes to the points of measurement,

read the measurement result on the display; the beep will be acti-
vated when resistance values are below approx.
50 Ω
.
5.7 Diode test
WARNING:
Do not perform measurements on the circuit under the volt-
age. Before the measurement disconnect the power and dis-
charge capacitors. Do not test the diode under voltage.
To perform the diode test:

set the rotary switch at
Ω
CAP
,

connect black test lead to COM terminal, and red test lead to
VΩHz%
mACAP
terminal,

press MODE button, to display and V on the screen,

contact the tips of test probes to the diode. The red test probe
should contact the anode and the black should contact cathode,

read the test result on the display
– the forward voltage is dis-
played.
