CIIL SOFTWARE COMMANDS (cont)
CIIL COMMANDS EXPLANATION
SRN VOLT <value> Optional. Sets minimum value limit for SET VOLT command. If
SETVOLT value is less than SRN VOLT value in a command string, an
error message is generated and a setup command ignored. The
following values are permitted:
/0 # value < 135, or 27 /0, dependent on range selected and type of unit.
The SET VOLT default is /0 for the minimum value if a value is not
specified for SRN VOLT.
SRX FREQ <value> Optional. Sets maximum limit for SET FREQ command. If the SET
FREQ value in a command string is grater than the maximum limit, an
error message is generated and the setup command ignored. Legal
values are:
45 < value # 5 /0 /0.
If a value for SRX FREQ is not specified, SRX FREQ defaults to 5 /0 /0.
SRN FREQ <value> Optional. Assigns minimum value to SET FREQ command. If the SET
FREQ value in a command string is less than the minimum limit, an
error message is generated and the setup command ignored. Legal
values are:
45 # value < 5 /0 /0.
If a value for SRN FREQ is not specified, SRN FREQ defaults to 45.
SET VLT /0 Set LO voltage range.
SET VLT1 Set HI voltage range.
Delay is necessary after issuing setup command, due to output voltage slew rate of 100v per 250 ms.
On dual range Power Supplies, this command selects the LO or HI voltage range. Dual Ranges are /0-
135 volts and /0-135/ /0-27 /0 volt. If this command is omitted from the setup string the unit will default to
the lowest available range. On single range units this command will be ignored.
NOTE
1. The setup command specifies the voltage and frequency of the AC power Supply output. The AC Power
Supply responds only to the last setup command entry. Its memory does not retain previously entered setup
commands.
2. During IEEE operation, the unit's front panel VOLTS and FREQ controls must be fully CCW. If the controls
are not set fully CCW, then the output voltage and frequency will be a sum of the programmed value and the
value set with the front controls. The front panel OUTPUT switch must be set to OFF position.
The front panel RANGE switch (on dual range units) must be set to LO.
