5.4. RESISTANCE
MEASUREMENT AND CONTINUITY TEST
CAUTION
Before attempting any resistance measurement, cut off power supply from
the circuit to be measured and make sure that all capacitors are discharged,
if present.
Fig. 9: Use of the instrument for resistance measurement and continuity test
1. Select the position.
2. Insert the red cable into input terminal
V
/+
and the black cable into input terminal
COM
.
3. If necessary, short-circuit the measuring leads and press key
/ZERO
to zero the
resistance of the measuring cables. The symbol
“
ZERO
”
appears on the display.
4. Position the test leads in the desired spots of the circuit to be measured (see Fig. 9).
The display shows the value of resistance.
5. If the display shows the message
“
>2000
”
(see Fig. 9) the maximum measurable
value has been reached.
6. Press key
MODE/MXMNPK
to select
“ ”
measurement, relevant to the continuity test,
and position the test leads in the desired positions of the circuit to be measured.
7. The value of resistance (which is only indicative) is displayed in
and the instrument
sounds if the value of resistance is <30.
8. To use functions HOLD, MAX/MIN, H/H%/H , see §. 4.2
