PAT100 SERIES
Handheld portable appliance testers
An additional 250 V dc insulation test is available on all models
for use on IT equipment, on devices or extension leads that are
fitted with surge protection, or simply where it may be considered
undesirable to use a 500 V test.
Substitute leakage testing
Substitute leakage testing enables the measurements of AC leakage
currents, which could differ significantly from the DC Insulation test
results.
Substitute leakage testing is performed at less than 40 V ac. and
does not require a mains supply.
Substitute leakage testing is used for measuring protective
conductor current and touch current, in addition to an insulation
test, or where it is considered an insulation test may damage
equipment.
The Substitute leakage test will not operate equipment and so
can be used where the operation of the equipment under test is
undesirable.
Portable RCD testing (PRCD)
Portable RCDs can be tested using the PAT150. There is no need
to find a non-RCD protected supply as the PAT150 will not trip
external RCDs.
Both 10 mA and 30 mA RCDs can be tested both for disconnection
times and the manual test button function.
Separated Extra Low Voltage (SELV) supplies
SELV supplies should be tested to ensure the output voltage
does not exceed maximum limits as defined in the international
regulations for Extra Low voltage systems. The PAT150 permits up
to 50 V ac measurement, with a PASS or fail indication for SELV.
Differential Leakage (Protective Conductor Current), Touch
Current & operational test
The PAT150 includes the facility for mains powered leakage test.
This test has the benefit that equipment under test will function
during the test sequence.
Battery life
The PAT120 & PAT150 operates from AA Alkaline or NiMH cells.
Battery life is typically 4 days, based on 120 assets per day.
The PAT150R can be re-charged with NiMH batteries fitted.
