SAFETY WARNINGS
Safety warning must be observed during use:
n
The circuit under test must be switched off, deenergised, isolated and checked to be safe before insulation test connections are made. Make
sure the circuit is not reenergised whilst the instrument is connected.
n
Circuit connections must not be touched during an insulation test.
n
After completing a test, capacitive circuits
must
be completely discharged before disconnecting the test leads.
Capacitive charges can be
lethal.
n
Tested items should be firmly shorted out with a shorting link, after discharge, until required for use. This is to guard against any stored
dielectric absorption charge subsequently being released thereby raising the voltage to potentially dangerous levels.
n
The voltage indicator and automatic discharge features should be regarded as additional safety features and not a substitute for normal safe
working practice.
n
It is rare, but in certain circumstances, breakdown of the circuit under test may cause the instrument to terminate the test in an uncontrolled
manner, possibly causing a loss of display while the circuit remains energised. In this event, the unit
must
be turned off and the circuit
discharged manually.
n
Test leads, including crocodile clips,
must
be in good order, clean and with no broken or cracked insulation.
n
The instrument should not be used if any part of it is damaged.
n
Insulation testing in wet weather conditions might be hazardous. It is recommended that this instrument is not used in these circumstances.
If this is unavoidable, the user must take all necessary precautions.
n
This instrument is not intrinsically safe and
must
not be used in hazardous atmospheres.
n
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
n
Rechargeable batteries
should not
be used on this instrument.
NOTE
THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.
Users of this equipment and/or their employers are reminded that National Health and Safety Legislation requires them to carry out valid risk
assessments of all electrical work so as to identify potential sources of electrical danger and risk of electrical injury such as inadvertent short
circuits. Where the assessments show that the risk is significant then the use of fused test leads may be appropriate.
