on the display when the input signal is steady (3 samplings with a maximum difference of
10% between the highest and the lowest value). The instrument automatically quits the
function after approx. 30s seconds.
4.3.3. V/
Ω
/ key
CAUTION
The instrument switches on in
Ω
mode
.
The
instrument
automatically
switches to VAC or VDC if the following
voltages are detected:
VAC > ca. 1.5V ; VDC > ca. 1.0V
The instrument
automatically
switches to
Ω
mode with the following
measured voltages:
VAC and VDC < ca. 0.6V
Press the
V/
Ω
/
key to manually select resistance measurement and
continuity test.
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
–
part 2).
1. Switch on the instrument by pressing the
ON/OFF
key.
2. Bring the NCV sensor closer to the potential AC source.
