5.3. CONTINUITY / DIODE TEST
HT5 allows continuity and diode tests with optical and acoustic indication.
CAUTION
Prior to any continuity test, it must be ensured that the resistance to be
measured is not live. Failure to comply with this prescription can lead to
dangerous user injuries.
Continuity test procedure:
• Touch contact “Electrode” (see Fig. 1 - point 4) during continuity test
• Connect test probe (see Fig. 1 – point 1) to one pole of the device under test
• Touch with the other hand the other pole of device under test
• The lighting of the LED "Continuity / Voltage" and the continuous sound of the buzzer
indicates continuity.
The continuity test facility enables resistance tests between 0 and approx 5 MΩ. The
resistance value can be determined by the intensity and the sound level of the acoustic
signal. A higher sound level indicates a lower resistance value (approx. 0Ω).
Simultaneously the LED Continuity is illuminated.
Diode test procedure:
• Touch contact “Electrode” (see Fig. 1 - point 4) during diode test
• Connect test probe (see Fig. 1 – point 1) to the diode cathode
• Touch with the other hand the diode anode
• The LED "Continuity / Voltage" must be turned on and the buzzer must sound.
• Connect test probe (see Fig. 1 – point 1) to the diode anode
• Touch with the other hand the diode cathode
• The LED "Continuity / Voltage" must be turned off and the buzzer must not sound.
