• If turned in the opposite direction, the stop lock bolt does engage, too. This could, however, loosen the sensor holder. The reason for this are adhesions on the lower part of the sensor holder. These can cause the sensor holder to get stuck, producing a counterforce when unscrewing the sensor holder. Endress+Hauser... - Page 17 Remove the sensor in the reverse sequence of operations. In case of symmetrical pH measurement, you must push the PML connector onto the PML connection (PML = potential matching line, position 1). Please, read the Operating Instructions of the transmitter.
