This test verifies that the voltage programming and
measurement functions are within specifications.
1. Turn off the power supply and connect the DVM from
the PCS-1000 directly across the +S and -S terminals as
shown in the fig. 1 connection.
2. Turn on the power supply and program the output
voltage to zero and the output current to its maximum
programmable value (Imax) with the load off. The CV
indicator should be on and the output current reading
should be approximately zero.
3. Record the output voltage readings on the digital
voltmeter (DVM) and the voltage measured over the
interface. The readings should be within the limits
specified in the test record form for the appropriate
model under Voltage Programming and Measurement,
Minimum Voltage Vout.
4. Program the output voltage to its full-scale rating.
5. Record the output voltage readings on the DVM and
the voltage measured over the interface. The readings
should be within the limits specified in the test record
form for the appropriate model under Voltage
Programming and Measurement, Rated Voltage Vout.
