4.3.3. Resistance and Continuity Test measurements

CAUTION

Before taking resistance measurements in circuit remove power from the

circuit being tested and discharge all capacitors.

Fig. 4: Using the instrument for resistance and continuity test measurements

1. Switch on  CAP. “” symbol is displayed

2. Insert the test leads into the jacks, the red plug into VHz% CAP jack and black

plug into COM jack (see Fig. 4)

3. Connect the test leads to the circuit under test. The resistance value is displayed

4. If the message "O.L" is displayed the higher range is reached

5. Pressing the MODE key until the symbol is shown at display to meaning the

Continuity test and connect the meter as resistance measurement. Buzzer emits sound

if the measured resistance value is <150

6. For HOLD function please refer to § 4.2
