WORKING SAFELY WITH CAPACITIVE LOADS
Circuit connections and the instrument terminals may become
hazardous when connected to Capacitive loads.
1.
These instruments are designed to safely charge and discharge
capacitive loads up to 5 µF. To safeguard against malfunction however,
you are advised to take your own precautions when working with
capacitive loads. Remember that when charged, even low value
capacitors can be fatal on contact .
2.
Extra care must be taken if the locking Test button is selected.
3.
Circuit connections must not be touched when testing.
Do not forget to release a locked Test button and discharge
any capacitance before touching the item under test or
disconnecting the test leads.
4.
Care must be taken to prevent capacitive circuits becoming
disconnected during a test, leaving the circuit in a charged state.
5.
On completion of a test, the instrument indicates circuit decaying
voltage. Do not disconnect test leads until the load capacitance has
discharged to below 60 V .
6.
The voltmeter and automatic discharge feature of the instruments
should be regarded as additional safety features and not a substitute
for normal safe working practice.
7.
If any part of the instrument is damaged, it should not be used, but
returned to the manufacturer or an approved service organization for
repair.
