Once again, the power supply should be addressed to talk and the results displayed (i.e. shown on CRT, printed, or
saved).
The PPS-2322 have two outputs, please refer to the programming syntax commands for proper nomenclature of
commands.
5.5.3 OVERVOLTAGE PROGRAMMING (OVSET)
In order to protect loads against excessive voltages, an overvoltage protection circuit (SCR crowbar) has been
added. When a voltage exceeds the set overvoltage value, the power supply output is disabled.
To program overvoltage, specify the output channel (PPS-2322 only) and overvoltage value. For example, to
program one channel of the PPS-2322 for 18 V, Enter:
OVSET1 18
To readback the programmed value for channel one, send the query:
OVSET1?
and address the power supply to talk. When specifying the queries, only one command may be issued at a time.
The power supply can access only one query at a time.
5.5.4 CURRENT PROGRAMMING
To program a current, specify an output channel (only PPS-2322) and current. All values of current must be in
amps. Additionally, the unit rounds off ISET to the nearest multiple of resolution. For example, to specify a current
of 1.6 amps. Enter:
ISET 1.6
This operation holds true for current settings in CC mode. When the supply operates in CC mode, the actual
current is the programmed current and the programmed voltage is the voltage limit.
To readback the programmed value, send the query:
ISET?
and address the power supply to talk.
To read back the current output of the channel, send the query:
IOUT?
Once again, the power supply should be addressed to talk and the results displayed (i.e. shown on CRT, printed, or
saved).
The PPS-2322 have two outputs, please refer to the programming syntax commands for proper nomenclature of
commands.
