„
Local Health and Safety Legislation requires users of this equipment and their employers to carry out valid risk
assessments of all electrical work 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.
„ The voltage indicator and automatic discharge features must be regarded as additional safety features and not a
substitute for normal safe working practice which MUST be followed.
„
The circuit under test must be switched off, de-energized, securely isolated and proved dead before test
connections are made unless measuring voltage or phase rotation.
„ Circuit connections, exposed conductive parts and other metalwork of an installation or equipment under test
must not be touched during testing.
„
When inductive loads are measured it is essential that the current carrying leads are securely clamped to the item
being tested and that they are not removed before any stored charge has been discharged at the end of the test.
Failure to comply with these instructions might result in an arc being produced, which might be dangerous for
the instrument and the operator.
„ The Voltmeter function will operate only if the instrument is switched on and working correctly.
„
After an insulation test, the instrument must be left connected until the circuit has been discharged to a safe
voltage.
„ The instrument must not be used if any part of it is damaged or if the terminal shutter is missing.
