Sensor error

Replace the sensor

The device exceeded the

maximum calibration

interval by 50%

Calibration is necceserry

129

The measured value

exceeds the range of -

10%

If the error persists,

contact the

manufacturer

3. Signalization transmitted by the current loop 4-20mA

Measurement:

The measure concentration is directly proportional to 4-20mA current output

Exceeding the range of measured concentrations:

Current output ranges from 20-22mA

End of valid calibration:

Current output transmits the actual measured concentration for 9s in a 4-20mA range and for 1s 2mA

current

Malfunction:

Current output will be set to 0,5mA

Mainternace:

Current output will be set to 1mA

Package content

1x sensor

1x grommet
