Troubleshooting instructions
Troubleshooting must take account of the whole measuring system. The measuring system
consists of:
• Transmitter
• Electrical leads and connectors
• Assembly
• Sensor
The possible causes of failure listed in the following table primarily refer to the total chlorine
sensor. Before commencing troubleshooting, please ensure that the following operating
conditions in "Technical data" are met:
• Chlorine content lies within the corresponding measurement range of the sensor
(0.1 ... 10 mg/l)
• Constant pH in the range 5.5 - 9.5
• Constant temperature in the range 4 ... 45 °C (39 ... 113 °F)
• Conductivity: 0.03 ... 40 mS/cm
• Flow: 30 ... 100 l/h (7.92 ... 26.40 US.gal./h)
If the value measured by the sensor differs significantly from that of the DPD method you need
to first consider all possible malfunctions of the DPD photometric method (see operating
instructions of the photometer). If necessary, repeat the DPD measurement several times.
