NO MODEL NUM 15 The interface cannot find its model number. There may be a hardware failure or
the instrument may require reprogramming. Service is required.
CAL ERROR 16 You tried to use either a calibration command with CMODE off or the calibration
failed while in CMODE. Enable CMODE and check numbers sent during
calibration. Also, there could be a hardware error.
UNCALIBRATED 17 There is an incorrect checksum in the EEPROM possibly as a result of incorrect
calibration procedure. Recalibrate, and if the problem persists, your supply has a
hardware failure.
CAL LOCKED 18 Calibration was attempted with the Calibration Jumper on the GP-IB board in the
lockout position. Reposition jumper if desired. See Service Manual.
SKIP SELF TST 22 The self test jumper on the GP-IB board is in the Skip Self Test position. No self-
test was done. This is for diagnostics only. See Service Manual.

29 There is an incorrect checksum in the EEPROM for non-volatile state storage. The non-volatile states 0-3
have not been loaded. Store new values, if problem persists, your supply has a hardware failure.
30 The store limit has been reached for CMODE, store states 0-3, DCPON, or SRQ. The power must be
turned off/on to reenable.
