RECOMMENDATIONS

The needle must indicate 0 when at rest in the voltmeter setting; if not, adjust
it using the black screw in the centre (see picture above).
Do not connect the instrument to the terminals of a circuit of which the
voltage exceeds 600VAC or DC.
Before any resistance measurement, check that the circuit is not live (switch
set to voltmeter before connection).
After each insulation resistance measurement, let the circuit discharge
(needle on 0V; this takes a few seconds) before disconnecting the
instrument.

Measurement input terminals:
These accept safety plugs 4mm in
diameter.
Other indicators:
An orange indicator (Fig. 1) on the right
side of the instrument indicates that the
speed of the magneto is correct. When it is
lit, the voltage between the termina ls of the
instrument is 500V, 650V, or 10VDC (no -
load), depending on the setting of the
switch.
A red indicator (Fig. 2) on the left side of
the instrument indicates the automatic
change of range. When it is lit, multiply the
reading by 10 to obtain the result.
