W103 = Initializing
If the message does not disappear, replace the electronics
W153 = Initializing
• Wait a few seconds
• If the error remains active, switch the voltage off/on
W601 = Linearization curve not monotone
Correct the table, enter a table that increases monotonically
W611 = Less than 2 linearization points
Enter more value pairs
W621 = Simulation on
Switch off the simulation mode,
