Checking and adjusting the microswitches (Fig. 4)
To set a microswitch, slide it by hand to the desired position.
CAUTION
Do not slide the microswitches on the colored indicator
points. The indicator points may break off or be bent.
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
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.
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.

The pointer must never be turned anti-clockwise to lower
temperatures. This will damage the measuring system.
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 which 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.
