Internal device errors
After power up, the instrument checks the calibration data in the data memory, the non-volatile
variables in the data memory and the EEPROM on the analogue card. Since more than one error
can occur at once, the errors are binary coded and displayed on the LCD in the event of an error.
Bit 0 set means that
non-volatile data in the RAM has been lost.
Bit 1 set means that a new device software version has been found (version number).
Bit 2 set means that the EEPROM has not been programmed yet or is faulty.
Bit 3 set means that calibration data in the data memory has been lost.
Bit 4 set means that there is a hardware fault (the node voltage (approx. 0.95V) is not OK)
Bit 5 set means that the internal protection circuit has been damaged.
The error code is displayed as a hexadecimal code:
