Test considerations
– Ensure that the calibration ambient temperature is stable at 23 °C ± 5 °C.
– Ensure ambient relative humidity is less than 70%.
– Allow a 30 minutes warm-up period before verification or calibration.
– Keep cables as short as possible, consistent with the impedance requirements.
– Performance verification and calibration procedure can be performed either through front panel or rear panel
input.
The tests should be performed by qualified personnel. During performance verification tests, hazardous voltages
may be present at the outputs of the power supply.
