Replacement process:
In order to replace the membrane cap, the old membrane cap is turned clockwise to loosen
it from the sensor.
Please check whether the O-ring on the membrane is correctly positioned and has not dete-
riorated (see below). The thread may be rubbed with some lubricating grease. If the O-ring
is damaged, it must also be replaced. It is included in the scope of delivery contents of the
new sensor cap.
Remove the new sensor membrane from the packaging and inspect the inside and outside
to determine whether it is absolutely dry and clean. Otherwise, use a lens cleaning cloth to
clean or dry it (see "Accessories").
The new sensor membrane is placed on the sensor tip and screwed in place anticlockwise.
Only hand-tighten the membrane; otherwise leaks or damage may occur. The sensor should
then be stored as described in 6.2 "Safekeeping". The Micro SD card supplied with the new
sensor membrane should be inserted in the memory card slot of the instrument. After the
probe has been connected to the instrument, the instrument should be switched on. When
switching on, the serial number of the new sensor membrane is shown in the display. The
new sensor membrane should then be calibrated. (see "Calibration", section 8)
