Startup procedure for manually operated housings

Before startup, all fitting and installation work (see Section 4.2)
must have been completed! Each time before startup, check the
measuring system, inspect the electrode/sensor assembly and
examine for leaks from housing and apparatus (see also Sec-
tion 7). Do not begin operation until the measuring system has
been checked and any necessary corrective action has been
taken.
Proceed as follows for startup:

protective sleeve "3", and attach the plug to the electrode.
replace the cable antikink "2".
The compensation pressure can be set with a bicycle pump
via the valve core at the pressure gauge, or established by
attaching a permanent (oil-free) compressed air supply
(using the pressure connection set included in the standard
equipment).
Note: To ensure electrolyte flow from the reference electrode
to the sample medium, the air pressure in the upper part must
be at least 0.5 bar and max. 2 bar above that of the sam-
ple medium (take hydrostatic pressure of the sample medi-
um into account).

1. Pull the red knob of the locking pin in
order to release the immersion tube.
2. Move immersion tube to the "Mainte-
nance" position. The tube must enga-
ge the lower limit stop (for "InTrac
777-SLM"). When the handle (pro-
tective sleeve) reaches the positio-
ning pin "A", the immersion tube
should be turned clockwise until the
recess in the handle (protective slee-
ve) is in alignment with the positio-
ning pin "A". The immersion tube can
now be fully inserted into the "Mea-
suring" position. There is an audible
click when the locking pin engages.
