Ac Voltage Measurement - Ht Instruments Ht10 Bedienungsanleitung

5.3. 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
•
Warning LED turns ON and the buzzer sound for
voltage between probes over 50V
1. Perform the preliminary Autotest function (see § 5.1)
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 and the "AC" indication switch on, the AC voltage
measurement is 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
turn on This is not a device problem
7. Press the H/ key to enable the HOLD function at display. Press
