DESCRIPTION OF FUNCTION KEYS

4.3.1. /

key

Pressing the /
for approx. 1s to turn off the instrument. With instrument switched on, press the
to activate/deactivate the integrated white light torch (see Fig. 1 - part 1). The symbol " "
appears on the display.

4.3.2. HOLD/ZERO key

Pressing the HOLD/ZERO key allows to activate/deactivate the Auto HOLD function. The
symbol A HOLD appears on the display and the buzzer beeps twice in a short time. With
" "
activated Auto HOLD function, the instrument automatically freezes the measured value
on the display when the input signal is steady (3 samplings with a maximum difference of
10% between the highest and the lowest value). Prolonged pressure (> 1s) of the
HOLD/ZERO key allows you to reset the residual magnetization in the DC current
measurement with the F100 clamp connected to the instrument (see § 5.5).
4.3.3. V/Ω/ /A
 The instrument switches on in Ω mode.
 The instrument automatically switches to VAC or VDC if the following
voltages are detected:
 The instrument automatically switches to Ω mode with the following
measured voltages:
 Press the V/Ω/ /A
continuity test (with F100 clamp disconnected)
 With F100 clamp connected, press the V/Ω/ /A
current measurement (
 Prolonged pressure (>1s) of the V/Ω/ /A
activation/deactivation of the display backlight

4.3.4. Detection of AC voltage without contact

The instrument allows detecting the presence of AC voltage without contact by using the
NCV sensor found on the upper part (see Fig. 1
