3.7 Setting the temperature of the measuring shaft
Before the instrument leaves the factory the temperature control of the measuring shaft
is set to 15
°
C. The temperature control of the measuring shaft can be switched on or
off.
The temperature control can be adjusted. To do this, measure the measuring shaft
temperature with an accurate thermometer. (Introduce about 1 ml water into the
measuring cuvette and place the cuvette in the measuring shaft. Measure the water
temperature after the temperature adjustment.) In the adjustment program, enter the
measured temperature via <F1> or <F2> as the actual temperature. The program
calibrates the temperature control so as to reach the required temperature of 15
°
C.
