1.1.4 Safety maintenance habits
• When opening instrument shell
or
dismantling battery cover,
plug
out
the test pens
first
I
• During maintenance
of
instrument,
use
specified
replacement parts.
• Before opening the instrument, cut
off
all
related power
supply, meanwhile guarantee you're
not
statically electrified
to
avoid damaging components
of
the instrument.
•
The
calibration and maintenance
of
instrument could only
be
done by special personnel.
• When opening the instrument, note some capacitance inside
the instrument may still have dangerous voltage even after
power-off.
•
If
any abnormality of the instrument
is
observed, stop the
instrument immediately and send
for
maintenance.
Guarantee
to
use
only after qualified by inspection.
• When
not
in
use
for
a long time, take down the batteries,
and avoid storing them in high temperature and high
humidity.
1.2
Input
protection
measures
• During voltage measurement, the withstand max.
input
voltage
is
DC
600V
or
AC
600V.
• During frequency, resistance,
on-off
and diode measurement,
AC
voltage
of
600V
or
voltage
of
equivalent
RMS
could
be
withstood.
• During measurement
of
µA
current and mA current, protect
