8. Indicator correction
Any interference with or modification to the instrument will
invalidate the warranty!
Indicator corrections may only be carried out by the manufacturer or in
adequately equipped workshops by qualified persons.
Electrical connection should only be carried out by qualified electricians
The switches are terminated on screw terminals or spade plug
Conductor cross-section max. 1.5 mm 
The terminal assignment is stated on the connection plate of the thermometer
To adjust red set pointers
The red set pointers are adjustable via the adjustment lock on the window.
The red set pointers for the micro switches are adjustable over the full range
of the instrument. Switching points should be set in the range between 10 %
und 90 % of the full scale, to ensure switching accuracy and the long life of the
measuring mechanism.
The non-adjustable switching points to customer specifications are not
changeable afterwards.
Surface oxidation at the contact areas may lead to malfunction, which can
result in contact-arcing, particularly in the case of intrinsically safe circuits (low
voltages and currents), and in the case of relatively high contact loads.
