The SCPI Status Registers
92
To determine the operating mode (CV or CC) for the power supply send
STAT:QUES:INST:ISUM<n>:COND?
, where n is 1, 2, or 3 depending on
the output. Bit 1 true indicates the output is in constant voltage mode, bit 0
true indicates constant current mode, both bits true indicates neither the
voltage nor the current is regulated, and both bits false indicates the outputs
of the power supply are off.
The Questionable Status Event register is cleared when:
• You execute the
*CLS
(clear status) command.
• You query the event register using
STATus:QUEStionable
[:EVENt]?
(Status Questionable Event register) command.
For example, 16 is returned when you have queried the status of the
questionable event register, the FAN condition is questionable.
The Questionable Status Enable register is cleared when:
• You execute
STATus:QUEStionable:ENABle 0
command.
For example, you must send the
STAT:QUES:ENAB 16
to enable the FAN bit.
