Bit Decimal Value Definition
4-15 Not used 0 Always be 0.
Sending
:STATus:QUEStionable:INSTrument:ISUMmary[<n>]:CONDition?
will query
the current operation mode (CC or CV) of the corresponding channel. bit0 true
indicates constant current mode; bit1 true indicates constant voltage mode; both bits
true indicates that neither the voltage nor the current is regulated, and both bits false
indicates that the outputs of the power supply are off.
3.2 Standard Event Register
The standard event register reports the following types of instrument events: power-
on detection, command syntax errors, command execution errors, self-test or
calibration errors, query errors, or an operation is complete. Any or all of these events
can be reported to the bit5 (ESB, Event Summary Bit) of the status byte register
through the enable register. To set the enable register mask, you need to write a
decimal value to the register using
*ESE
. The definitions of the bits in the standard
event register and the decimal values corresponding to their binary weights are as
shown in the table below.
An error condition (bit2, bit3, bit4, or bit5 of the standard event register) will record
one or more errors in the power supply's error queue. You can
send
:SYSTem:ERRor[:NEXT]?
to read the error queue.

values corresponding to their binary weights
Bit
Decimal
Value
Definition
0 OPC 1
Operation complete. All commands prior
to and including the
*OPC
command have
been executed.
1 Not used 0 Always be 0.
2 QYE 4
Query error. The power supply tried to read
the output buffer but it was empty, or a
new command line was received before a
previous query had been read, or both the
input and output buffers are full.
3 DDE 8
Device error. A self-test or calibration error
occurred.
4 EXE 16
Execution error, including trigger ignore,
initialization ignore, setting conflict, data
overrange, data too long, and invalid
parameter value.
5 CME 32
Command error. A command syntax error
occurred.
