5. OPERATING INSTRUCTIONS

5.1.

DC VOLTAGE MEASUREMENT

 The maximum input for DC Voltage is 1000V. Do not measure higher
voltages to avoid risks of electrical shocks or serious damages to the
instrument

probes over 120V
1. Perform the preliminary Autotest function (see § 4.4)
2. Connect the L1 and L2 probes to the object under test (see Fig. 4). The measurement
is performed only with contact of probes directly on metal parts of conductors
3. The instrument switches on automatically for voltage >6V and the DC voltage value is
displayed both through red LEDs switching on and on the display. DC symbol is
displayed and "+" LED switches on
4. Should symbol "-" be displayed it means that the detected voltage has an opposite
direction compared to the connection shown in Fig. 4
5. The instrument turns automatically OFF as soon as probes are disconnected from the
object under test
6. Press the H/ key to activate/deactivate the function HOLD at display. Press and hold
the H/ key in order to activate/deactivate the display backlight
7. Press the / key to activate/deactivate the white LED torch
Warning LED turns ON and the buzzer sound for voltage between
