In order to ensure safe operation of this instrument, all notes and
warnings in these instructions must be observed at all times.
The DL9120 / DL9130EV has been designed to make
measurements in a dry environment.
The DL9120 / DL9130EV may be used to test circuits with
a maximum over-voltage Category III, 300 V AC/DC with
reference to earth.
When making connections using the test probes always
hold test probes above the hand guards.
The DL9120 / DL9130EV 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 DL9120 / DL9130EV 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 DL9120 / DL9130EV is used in a manner not specified
