Safety Warnings
The following safety warnings and precautions
must be
read and understood before the
instrument is used. They must be observed during use.
n
For safety, only connect the PAT to a supply that is properly earthed. If in doubt, the
supply should be checked by a qualified electrician.
n
Do not use
the instrument if there are any signs of damage.
n
All test leads, probes and clips
must be
in good order, clean and with no broken or
cracked insulation.
n
Probes and clips should be held behind the finger guard.
n
Test leads not used during a measurement should be disconnected from the appliance
tester.
n
For dual voltage testers, both sockets can be live simultaneously.
n
Only connect one asset to the PAT during testing.
n
Tests should be carried out in the order recommended below. An appliance that fails a
test should be repaired before further testing is carried out.
Recommended sequence:
1. Visual inspection.
2. Earth bond/ continuity of the protective earth conductor (Class I devices).
3. Insulation test (or earth leakage).
In addition further tests can be performed, but ONLY AFTER 1 & 2 above.
4. Operation test.
5. Leakage test.
n
Only perform an operational test after the earth bond and insulation tests have been
completed, as this test operates at mains voltage.
n
During testing, ensure no hazard will exist as a result of normal running or under fault
conditions.
n
During testing the unit under test (asset)
should not
be touched, other than using the
appropriate accessories, as faulty appliances can present a shock hazard.
n
Do not
touch the exposed parts of test leads during tests as hazardous voltages may be
present due to potentially faulty appliance.
n
Do not
touch the IEC extension lead socket pins especially during a test, as hazardous
voltages may be present due to a potentially faulty appliance.
n
Assets
should not
be routinely flash tested. Where flash testing is required, refer to
further guidance on flash testing in the user guide.
n
Replacement fuses must be of the correct rating and type. Refer to the user guide.
n
The USB connection marked thus
should only be used by approved service
personnel; nothing should be connected to the USB port during testing.
n
Only use a NiMH rechargeable 8.4 V PP3 battery,
do not
use a non rechargeable type as
this could become dangerous if charged by the instrument.
n
Serviceable fuses
should
only be replaced with those that are suitably rated.
n
In case of an emergency use an easily accessible power point.
n
Only use Megger approved accessories with this product.
