Test considerations
– Ensure that the calibration ambient temperature is stable and between 20 °C and 30 °C.
– Ensure ambient relative humidity is less than 80%.
– Allow a 1-hour warm-up period before verification or calibration.
– Keep cables as short as possible, consistent with the impedance requirements.
– Performance verification and calibration procedure must be performed through front panel output.
The tests should be performed by qualified personnel. During performance verification tests, hazardous voltages
may be present at the outputs of the power supply.
