Gel sensor installation
Remove the sensor in the reverse sequence of operations.
!
Note!
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.
1. Remove the splash protection cap (Fig. 15,
pos. 1) from the assembly.
2. Take care that the surface of the retractable
pipe (pos. 3) is not damaged. The surface is a
seal face. Loosen the retractable pipe by
turning it counterclockwise.
3. Install the sensor (pos. 7) instead of the
dummy plug (pos. 4):
– first screw by hand
– then tighten the sensor by approx. ¼ turn
using an open end wrench (AF 17).
4. Insert the measuring cable (pos. 6) through
the retractable pipe :
– Fixed cable:
from the bottom through the retractable
pipe, from the sensor to the transmitter
– Plug-in head sensor:
from the top to the sensor head
5.
Plug-in head sensor only:
Connect sensor and cable.
6. Screw the retractable pipe back onto the
electrode holder (pos. 5)(clockwise, by
hand).
7. Place the measuring cable in the splash
protection cap and place the cap on the
retractable pipe.
8. Put the PML plug onto the PML terminal
(PML = potential matching line, pos. 2)
