5. INSTRUMENT FUNCTIONS
5.1. PHASE DETECTION
The HT5 can be used as phase detector in the presence of voltage between 60V and
250V AC.
Measurement procedure:
• Touch contact “Electrode” (see Fig. 1 - point 4) during voltage test
• Connect test probe (see Fig. 1 – point 1) to the device under test
• Illumination of the LED “Continuity/Voltage” indicates the presence of an AC voltage
between 60V and 250V. Simultaneously an acoustic sound is audible.
CAUTION
• A correct indication is only ensured for AC voltage circuits with a
frequency of 40-60 Hz being grounded in accordance with the
regulations
• The quality of the indication may be impaired when testing in
unfavourable locations, such as wooden ladders or in insulated floor
coverings, etc.
