15.
Calculate the power as follows: P = Iin x Vin. Vin is the voltage measured by the second DMM. The readings
should be within the limits specified in the test record form for the appropriate model under “Power
Programming & Readback - Medium range, Maximum power”.
Low range
16.
Program the load settings as described in the test record form for “Power Programming - Low range, Minimum
power”. Program the power supply to the power supply settings described in the test record form.
17.
Divide the voltage drop (DMM reading) across the current shunt by the shunt resistance to convert to amps and
record this value (Iin). Also record the current measured over the interface.
