the configured input signal limit.
nnnnn Measured value is below the value allowed for the selected sensor or below
the configured input signal limit.
----- Open input. No sensor is connected or the sensor is broken.
Err 1 Pt100 cable resistance is too high or the sensor is badly connected.
Different messages other than the ones above should be reported to the manufacturer. Please inform
the serial number if this should occur. The serial number can be viewed at the display by pressing the
key for about 3 seconds.
