Ac Voltage Measurement - HT 10 Manuel D'utilisation

5.2.

AC VOLTAGE MEASUREMENT

 The maximum input for AC Voltage is 1000V. Do not measure higher
voltages to avoid risks of electrical shocks or serious damages to the
instrument

probes over 50V
1. Perform the preliminary Autotest function (see § 4.4)
2. Connect the L1 and L2 probes to the object under test (see Fig. 5). The measurement
is performed only with contact of probes directly on metal parts of conductors
3. The instrument switches on automatically on for voltage >6V and the AC voltage value
is displayed both through red LEDs switching on and on the display. AC symbol is
displayed
4. The LED
displayed and an acoustic signal is emitted
5. The instrument turns automatically OFF as soon as probes are disconnected from the
object under test
6. For measurements in single-phase plants the LEDs
device problem
7. Press the H/ key to enable the HOLD function at display. Press and hold the H/
in order to activate/deactivate the display backlight
8. Press the / key to activate/deactivate the white LED torch
Warning LED turns ON and the buzzer sound for voltage between
