Table 6-2: Model 1140A Error Codes
Code Description Returned Explanation
0 No error
101 Temperature out of range The simulation temperature being programmed is out of
range for the current thermocouple type.
102 Reference junction temp
out of range
The reference-junction temperature being programmed is
out of range for the current thermocouple type.
103 Temp out of range for
thermocouple
The current reference-junction temperature is out of range
for the thermocouple type being programmed.
104 Ref jct out of range for
thermocouple
The current simulation temperature is out of range for the
thermocouple type being programmed.
105 Voltage out of range The voltage being programmed is out of range.
106 Output overload The Model 1140A is incapable of supplying the
programmed output.
107 Thermocouple invalid for
temperature scale
The thermocouple type commanded is not available in the
current temperature scale.
–100 Command error Unrecognized query, command, or command parameter.
–101 Command not allowed in
Standby mode
A command was received which could not be acted on in
Standby mode.
–315 Nonvolatile memory error An internal memory error occurred at startup.

have been discarded.
Query the First Error in the Queue :SYSTem:ERRor?
This command pops the oldest error out of the queue and returns its numeric code as well as
a brief description, separated by a comma. Refer to Table 6-2 for error codes.
Example: :SYST:ERR? might return −100,Command error.
Query All Errors in the Queue :SYSTem:ERRor:ALL?
Example: :SYST:ERR:ALL? might return:
−100, Command error
105,Voltage out of range
etc.
