3 PhASE SuPPLy FOR ThE
DEVICE uNDER TEST
Overview
The 3 Phase Run Test (where fitted) tests Portable 3 Phase
Appliances in accordance with AS/NZS 3760.
This option is available with 20A and 32A 3 phase sockets or
other current ratings as requested.
The test looks for an Earth Connection <=1.0 Ohm; a run
current to ensure the appliance is switched on and running;
and a leakage current of <=5mA. The test is a Long Run Test.
It may be shortened at any time after the test commences by
pressing “Reset” twice in quick succession.
If any of the test parameters (Earth Current, Run Current or
Leakage Current) fail, then the 3 phase test fails otherwise the
Pro Logger will indicate a pass.
Operation
This test requires 2 connections to the Pro Logger: an earth
return connection to the Device Under Test’s (DUT) chassis;
and a connection the 20 or 32A 3 phase socket adaptor (this is
a ‘din’ type socket in the well of the
SafeTcheck
).
The 3 phase socket adaptor is plugged into a 3 phase power
source, then the DUT into the 3 phase adaptor. The DUT must
be running to conduct a test.
To test a 3 phase extension lead, run a test with the extension
lead connected between an already tested (and known
electrically safe) 3 phase appliance and the 3 phase adaptor.
Select the 3 Phase Run Test option from the OTHER
APPLIANCE menu; use the F1 and F2 keys to scroll up and
down the list of options.
