CIIL COMMANDS

EXPLANATION

SET VOLT <value>

Sets output voltage to given value,in volts rms. The following values are
permitted:

0 < value < 135, or 270, dependent on range selected and type of unit.

If set volt (value) not received, then use SRN VOLT (value), or SRX
VOLT (value). If none of these 3 are sent then generate error message.

SET FREQ <value>

Optional. Sets frequency of output voltage to given value, in Hz. The
following values are permitted:

45 < value < 500.

Default is 45 Hz only if SET FREQ, SRN FREQ, or SRX FREQ are not
received.  Otherwise the values shall be used in the order stated.

SRX VOLT <value>

Optional. Sets maximum limit for SET VOLT command. If SET VOLT
value is greater than SRX VOLT value in a command string, an error
message is generated and the setup command ignored. The following
values are permitted:

0 < value < 135, or 270, dependent on range selected and type of unit.

If a value for SRX VOLT is not specified, the required maximum value
for SET VOLT default to 135, or 270, dependant on range selected and
type of unit.
