14.2.10 DSC?
The Device Status Condition register contains the power supply’s status, and returns a decimal value,
which expressed in base 2, reflects the bit values of the Device Status. Execution of this query will not
clear this register. The returned value is a NR1 response data type. See the power supply manual to
check which statuses are available
BIT MNE Description Device Status Condition register
0 CC Constant Current
1 LIM Limit
2 DCF DC Fail
3 ACF AC Fail
4 O.T. Over Temperature
5 PSO Power Sink Overload
6 InpA (CCR) User input A (CCR when used in a power supply with internal CPU)
7 InpB (CVR) User input B (CVR when used in a power supply with internal CPU)
14.2.11 DEE
This register is only available when a power supply is used with an internal CPU.
Device Extended status Enable. This command specifies the bit values of the Device Extended status
Enable Register. This register determines which events from the Device Extended status Register are
summarized in bit 1 of the Status Byte Register. A bit value 1 in the Device Extended status Enable
Register selects the corresponding bit in the Device Extended status Register to be reported in Bit 1 of
the status byte, the Device Summary Extended status bit.
DEE?
The Device Extended status Enable query returns a decimal value, which expressed in base 2, reflects
the bit values of Device Extended status Enable Register. The returned value is a NR1 response data
type.
Bit MNE Description Device Extended status condition Register
0 HOT High temperature
1 INTL Interlock
2 VLIM Voltage limit
3 ILIM Current limit
4 CV Constant voltage mode
5 OUTP Output on
6 RSD Remote shut down
7 FPL Front panel lock
14.2.12 DER?
The Device Extended status Register contains the power supply Extended status change , and returns a
decimal value, which expressed in base 2, reflects the bit values of the Device Extended status register.
Execution of this query causes the Device Extended status Register to be cleared. The returned value is
a NR1 response data type.
14.2.13 DEC?
The Device Extended status Condition register contains the power-supply status, and returns a decimal
value, which expressed in base 2, reflects the bit values of the register. The returned value is a NR1
response data type. See the power supply manual to check which statusses are available.
