3. USE AND CHARACTERISTICS:
3.1. RECOMMENDATIONS
The needle must indicate 0 on the 600-scale when at rest; 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 600V
Before any resistance measurement, check that the circuit is not live (switch
set to 500V before connection).
After each insulation resistance measurement, let the circuit discharge
(needle on 0V; this takes a few seconds) before disconnecting the
instrument.

AC DC
Measurement input terminals: These
accept safety plugs 4mm in diameter.
Other indicators:
A green 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 betwee n the terminals of the
instrument is 250V, 500V, or 1000VDC
(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.
