WARNING!
Do not use the calibrator if it is damaged. Before using the
■
instrument, check that there are no cracks or missing plastic parts on
the case. Pay particular attention to the insulation of the connectors.
The battery cover must be closed and locked in place before the
■
instrument is operated.
Remove the test cables from the instrument before opening the
■
battery compartment.
Inspect the test cables for damaged insulation or exposed metal.
■
Check the continuity of the leads. Damaged test leads should be
replaced before using the instrument.
When using test probes, keep fingers away from the test probe
■
contacts. Place fingers behind the finger guards on the test probes.
Do not use the instrument if it is not working properly. The instrument
■
protection might be compromised. If in doubt, have the instrument
checked.
Only use the instrument in classified areas for which the calibrator is
■
approved.
Disconnect test leads before changing to another measurement or
■
generation function.
To avoid false readings, replace the battery as soon as the battery
■
indicator appears.
Use the correct connection, the proper function and the correct
■
measuring range for measurements.
When screwing an adaptor onto the NPT thread of the calibrator, a
■
sealing material must also be used (e.g. PTFE tape).
When screwing on, use a spanner on the pressure connection for
■
fixing to the calibrator, in order to avoid unnecessary stress on the
case.
