2 Safety Notes
This DL9118 is fully compliant with the requirements of:
BS EN 61010-1: 2010
BS EN 61010-2-30:2010
BS EN 61557 part 1, 2, 3, 4, 6, 7 and 10.
In order to ensure safe operation of this instrument, all notes and
warnings in these instructions must be observed at all times.
The DL9118 has been designed to make measurements
in a dry environment.
The DL9118 may be used to test circuits with a maximum
over-voltage Category III, 300 V AC/DC with reference to
earth.
High voltages are present at the probe tips of the DL9118
during insulation resistance measurement. Always hold
test probes above the hand guards.
The DL9118 and all associated cables and leads must be
checked for signs of damage before equipment is
operated.
Prior to any resistance measurement, always ensure that
the circuit under test is electrically isolated.
Where safe operation of the DL9118 is no longer possible it should be
immediately shut down and secured to prevent accidental operation.
It must be assumed that safe operation is no longer possible:
- if the instrument or leads show visible signs of damage or
- the instrument does not function or
- after long periods of storage under adverse environmental conditions.
If the DL9118 is used in a manner not specified by this
document then the protection provided by the equipment
may be impaired.
