Notes:
[1] Test currents up to 30 % of maximum continuous test current can be applied to the Calibrator with no time limitation. Test
current between 30 % and 100 % of the maximum continuous test current can be applied to the Calibrator for a limited time.
Minimum period of full current load is 45 seconds. The Calibrator calculates the allowed time period and when exceeded,
the output connectors are disconnected.
[2] Maximum short term test current is defined as the rms value of halfwave or fullwave test current flowing through the UUT.
Maximum time of test is 200 ms. A time interval of 200 ms represents 10 full waves of power line voltage at 50 Hz and 12
full waves at 60 Hz.
