1-Wire Ac Voltage Detection (Polarity) - HT 10 Manuel D'utilisation

5.4.

1-WIRE AC VOLTAGE DETECTION (POLARITY)

 The maximum input for AC voltage is 1000V. Do not try to measure
higher voltages to avoid risk of electrical shocks or serious damages to
the instrument
 The 1-wire AC voltage mode should be used as a quick test in order to
detect the presence of voltage only without displaying any result. The
pole test is not suitable to determine voltage. For this purpose, the
two-pole voltage testing is always mandatory
 When using single-pole phase tests to determine external conductors
the display function may be impaired under certain conditions (e.g. for
insulating body, protective equipment on insulation locations, etc..

probes over 100V
1. Perform the preliminary Autotest function (see § 4.4)
2. Connect the L2 probes to the object under test (see Fig. 7). The measurement is
performed only with contact of probe directly on the metal part of conductor
3. The LED and the "- - -" indication switch on, and an acoustic signal is emitted for
voltage present >100V AC
4. The instrument turns automatically OFF as soon as probes are disconnected from the
object under test
5. Press the H/ key to activate/deactivate the HOLD function at display. Press and hold
the H/ key in order to activate/deactivate the display backlight
6. Press the / key to activate/deactivate the white LED torch
Warning LED turns ON and the buzzer sound for voltage between
