Load (Run) Current Measurement
It is advisable to only apply a Load Test if the product has successfully
undergone a Safety Test first.
Check that the product to be tested is connected to the correct test output
socket for the supply voltage required – 230V or 110V – and for 110V
products, that a suitable external supply source is connected to the
instrument.
NOTE
For 230V appliances the maximum permissible load current is 15A and for
110V equipment the maximum measurable current is 25A, provided that the
external supply is suitably rated.
Set the Test Selector to any of the safety test ranges but NOT Earth Leakage.
Depress & hold the LOAD TEST button and then operate the product - allow
sufficient time for the product to reach a steady state condition and then read
the current being indicated on the 0-25A, middle, scale of the meter.
To improve readability of low current values (below 2.5A), also depress the
2.5A button to expand the readout range – the previous value is now
multiplied by 10.
The indicated value should be within the limits specified, by the manufacturer,
for off-load operation.
Ensure that the appliance cannot move and is adequately
guarded to prevent any hazard being caused by or to moving
parts or heating elements during the application of the test
supply voltage.
