A PPENDIX 3: M ODBUS RTU D ATA S TRUCTURE
If the instrument is programmed for Modbus, it can be used as a Modbus RTU slave on a RS485
communication line or on the Ethernet communication line. The Modbus slave adress is defined in the
parameter [Address]. Function code “0x03” and function code “0x10” are supported.

Calibration
Errors
1
Calibration Timeout –
Restart calibration
2
ADC Error
– Re-energize the instrument
– If seen again, change board.
3
Instrument cannot be calibrated –
Check load cell cable
– Re-energize the instrument
34
Instrument cannot be calibrated – Load
cell signal is too low or too high
35
Calibration Error
– Calibration test weight is too small,
increase calibration weight value
(40031-32)
– Check load cell connections
37
Scale unstable
– Wait until scale becomes stable
– Check grounding wiring
38
Calibration Jumper is not installed-
Check Calibration jumper
