Fig. 6: Using the instrument for Resistance measurement and Continuity test
1. Selecting the position
/
2. Insert the test leads into the jack, the red plug into V
Hz
A jack and black plug
into COM jack
3. Connect the test leads to the circuit under test (see Fig. 6). The resistance value is
displayed
4. Pressing the R/SEL key to select the correct range or using the Autorange feature (see
§ 4.2). If the resistance value under test is unknown, select the highest range.
5. If the message "
O.L
" is displayed a higher range must be selected.
6. For continuity test press the R/SEL key until the symbol “
” is displayed and use the
test leads in the same way of resistance measurement. The buzzer is on for resistance
values <35
.
