The Questionable Status Register
The Questionable Status register provides information about unexpected
operation of the power supply. Bit 4 reports a fault with the fan, and bit 13
summarizes questionable outputs for any of the two supplies. For example,
if one of the two supplies is in constant voltage mode and due to an overload
looses regulation, bit 13 is set (latched). To read the register, send the
command
STATus:QUEStionable?
.
To make use of bit 13 you must first enable registers you wish to summarize
with bit 13. Send the command
STAT:QUES :INST:ENAB 6
to enable the
Questionable Instrument register, then send the command
STAT:QUES:INST:ISUM<n>:ENAB 515
for each supply to enable the
Questionable Instrument Summary register, where n is 1 or 2.
Table 4-3. Bit Definitions - Questionable Status Register
The Questionable Instrument Status Register
The Questionable Instrument register provides information about unexpected
operations for each of the two supplies. For example, if the output1 supply is
in the constant voltage mode and looses regulation, then bit 1 set indicating a
possible overload in the output1 supply. The output2 supply is reported as
bit 2. Send the command
STAT QUES:INST?
to read the register. The
STAT:QUES:INST:ISUM<n>
registers must be enabled to make use of the
Questionable Instrument register. Send the command
STAT:QUES:INST:ISUM<n>:ENAB 515
to enable output n.
