4.1.2 Fitting and filling the reservoir (option)

Note. The reservoir is supplied partially-assembled.
Assemble only immediately before using the wet-section (to
avoid the possibility of solution drying out if the wet-section
is stored for any length of time).
Referring to Fig. 4.2:
A
1. Push reservoir into clip
2. Slide the lower end of the reservoir tube
reference electrode filler tube
Note. Ensure the reservoir tube is not kinked and
does not contain air bubbles.
E
3. Remove filler cap from the reservoir
4. Fill the reservoir with 3.5 KCI solution and squeeze the
C
reservoir tube repeatedly to expel any bubbles.
G
5. Unscrew filler plug
to avoid creating a vacuum.
F
6. Ensure O-ring is in place and replace filler cap

4.1.3 Sensor panel

1. Fill the reagent solution container with appropriate
solution.
2. Open the shut-off valve upstream of the wet-section panel
and adjust it until sample is overflowing from the overflow
pipe of the constant-head unit.
The maximum and minimum flow rates are 400 to 100
ml/min (24.4 to 6.10 cu in./min).
3. Ensure that sample is passing from the constant-head unit
onto to the flowcell and that the entrainment of reagent is
operating; the entrainment should be regular, not
intermittent.
Allow at least one hour before carrying out a calibration.
4. If the wet-section is a multiple wet-section configuration,
check / set the DIP switches on the wet-section PCB –
see Appendix C, page 78.
5. Start-up the transmitter as described in the Section 4.2.
6. Perform a two-point calibration:
– for single-stream wet-sections refer to Section 5.2,
page 22
.
– for multi-stream wet-sections refer to Section 5.3,
page 23
7. The wet-section is now ready for use.

4.2 Transmitter start-up

Ensure all electrical connections have been made and switch
the power to the transmitter on. If the wet-section is being
commissioned for the first time, programming and calibration of
parameters is required – refer to Section 5.2, page 22
(single-stream) or Section 5.3, page 23 (multi-stream) to perform
a calibration for the first time.
The menu structure, general operation and menu descriptions,
including Calibration are detailed Section 7, page 42.
