5 Indication control and readjustment
4 .1 Connecting the microswitches (Fig . 3)
To connect the microswitches flip up the covering plate (Fig.
1/2). Remove the outer sheaths of the connecting cables to
a length of approx. 160 mm and then the insulation of the
individual conductors to a length of approx. 6 mm. Install
the cable glands provided loosely to the incoming cables and
housing. This must be done as shown in the appendix Fig. 8.
Pay close attention to cable gland assembly and ensure that
the seal is properly fitted to avoid any water ingress. Connect
the incoming wiring to the terminal strip (Fig. 3/1) in accord-
ance with the connection diagram (Fig. 3/3) printed on the
cover plate.
4 .2 Checking and adjusting the microswitches (Fig . 4)
To set a microswitch, slide it by hand to the desired position.
To check the microswitches which are located to the right
of the pointer, turn the pointer clockwise by hand past the
microswitches and back. A return spring pulls the pointer
back to its original position (Fig. 4).

CAUTION
The pointer must never be turned anti-clockwise to lower
temperatures. This will damage the measuring system.
CAUTION
Do not slide the microswitches on the colored indicator
points. The indicator points may break off or be bent.
CAUTION
Do not release the pointer here. It must be slowly retur-
ned to its original position. If the pointer snaps back, the
microswitches may be damaged.
Fig. 4
To check the microswitches which are located to the left of
the pointer, slide them clockwise past the pointer, in the same
way as when setting the microswitches. After checking, the
microswitches must be reset to their original positions.
5 Indication control and readjustment
The pointer thermometers are calibrated at the factory. If it
is necessary to readjust it, indication control and comparison
measurements should only be carried out in agitated water
baths in witch the temperature remains constant for several
minutes (approx. 15 min.). Readjustments are possible. The
adjustment screw (Fig. 1/3) is on the front of the instrument.
