Error Number List
This chapter gives the error numbers and descriptions that are returned by the
electronic load. Error numbers are returned in two ways:
⚫ Error numbers are displayed on the front panel
⚫ Error numbers and messages are read back with the SYSTem:ERRor? query.
SYSTem:ERRor? returns the error number into a variable and returns two
parameters, an NR1 and a string.
The following table lists the errors that are associated with SCPI syntax errors
and interface problems. It also lists the device dependent errors. Information
inside the brackets is not part of the standard error message, but is included for
clarification. When errors occur, the Standard Event Status register records
them in bit 2, 3, 4, or 5:
Command Errors 100 through 199 (sets Standard Event Status Register bit #5
CME)
Error Error String
101 device independed error
