4.3 Error Codes
The Model 135/136 returns specific error codes for invalid commands and/
or arguments. If an error condition is returned, the command is not
processed and the configuration of the instrument is not modified. The
table below provides a list of error codes, their meaning, and any
associated limits. The error codes are common to both the serial and IEEE-
488 communication options.
Error Code Meaning Valid Range
− 1 LO setpoint out of range 0 ≤ LO ≤ LENGTH
− 2 B setpoint out of range 0 ≤ B < A
− 3 A setpoint out of range B < A ≤ LENGTH
− 4 HI setpoint out of range 0 ≤ HI ≤ LENGTH
− 5 Attempted to set or query for
LENGTH in PERCENT units mode
− 6 Invalid argument, value out of
maximum calibration range
1 cm ≤ value ≤ 203.2 cm
− 7 INTERVAL setting out of range 0 ≤ INTERVAL ≤ 600 min
− 8 Unrecognized command
− 9 Invalid argument, value was negative
or non-numeric
