Removal of protective cap (if necessary)
For the protection of the diaphragm, some of the probes have a plugged-on
protection cap. If the device shall be used in highviscosity media such as
sludge, a removal of the cap before start-up is necessary. Thus, the sensor
becomes flush, and the medium will attain quickly to the diaphragm.
NOTE – Make sure that the sensor (7) under the protection cap will not be
damaged!
Removal by hand
- Hold the probe in a way that the protection cap points upwards.
- Hold the probe with one hand on the sensor section (1).
- Remove the protection cap (2) with the other hand.
Removal with a tool (recommended)
Fig.2 Removal of protection cap
- Hold the probe in a way that the protection cap points upwards.
- Slide a small tool such as a screwdriver (8) straight through two opposite drill holes in the protective cap (2).
- Lever it off by moving up the handle of the screwdriver.
