6.4 Returns
Please observe the following instructions when returning items.
If returning a sensor, please contact customer service first. To ensure hassle-free returns and avoid incorrect deliveries, each
return package must first be reported to the customer service. You will then receive a numbered RMA form, which you need
to fill out completely, check and send back to us. Please attach the form with the number so it is clearly visible on the outside
of the return package or write it in large numbers on the packaging. so that your return package can be correctly allocated
and accepted.
Please make sure that the sensor is cleaned and disinfected before shipping. In order to prevent damage to the goods during
shipping, use the original packaging. If this is not available, make sure that safe transport is guaranteed and that the sensor is
safely packed with enough packing material.
Caution! Return shipments without an RMA number cannot be accepted and processed!
Signal test After zero point test:
1. Add some disinfectant containing chlorine to the beaker filled with clean tap water from the
"zero point test"
2. Stir as evenly as possible for at least 5 minutes with the sensor connected to the measuring
instrument
3. During this time, you should notice an increase in the measuring signal
-> If the sensor signal increases, the sensor is likely to be OK. If the sensor does not react to the
chlorine-containing disinfectant, the sensor must be serviced in accordance with chapter 6.2 of
the operating instructions and the "Signal test" repeated.
-> If the sensor still shows no reaction to the chlorine-containing disinfectant after that, it must be
sent in for inspection.
Environment test 1. Check flow
2. Check measuring cable
3. Check measuring/control unit
4. Check correct calibration
5. Check dosing device
