TPL 3 PHASE
LEAKAGE CURRENT
METER
QUICK REFERENCE GUIDE
Thank you for your purchase of a TPL Series 3-Phase Leakage Current Meter. You can now safely, easily and accurately
measure 3-Phase leakage current without having to purchase bulky and expensive 3-Phase appliance testers.
As an added feature the unit incorporates an IEC socket to allow you to check earth continuity with your existing
appliance tester.
How to Measure 3 Phase Leakage Current
•
Unplug the appliance to be tested from the mains supply and plug the TPL into the appropriate mains socket
•
Plug the appliance to be tested into the appropriate test socket on the TPL
•
Turn the mains on at the supply and turn the appliance to be tested ON
•
Turn the TPL on. When you're ready to take your measurement depress and hold the Test button for a few seconds
and note the reading on the LCD display (at the time of writing these instructions the allowable earth leakage
current limit for a Class I device was 5mA AC as per AS/NZS 3760:2003). The LCD screen gives a direct in mA AC.
i.e. a display of 3.24 is 3.24mA AC and so on. (Note: If the display reads "1" on the left hand side of the screen this
means that the leakage current is greater than 20mA and the meter is over-ranging. This is an automatic failure of
the appliance under test).
•
As per best practice for appliance testing, the equipment under test should be turned on and running at maximum.
(I.e. The hottest or fastest setting). All switch positions and combinations should be tried to ensure that there is no
specific function which could cause excessive leakage.
•
Turn off the TPL and return all equipment to their previous states/locations.
How to do an Earth Resistance Test
•
ENSURE THE TPL IS SWITCHED OFF
•
Using a spare IEC lead plug one end into your appliance tester's test socket and the other end into the IEC socket on
the TPL (see Fig 2 below).
•
Plug the appliance under test into the appropriate socket on the TPL.
•
Attach your earth clamp to the appliance under test.
•
Perform an earth bond test as per usual procedures for your particular appliance tester.
