2. Professionally install module.

3. Add 1 % of the temperature span to the selected "minimum"

temperature and set this value on a PT 100 simulator (when

using a precision resistance decade, where necessary ob-

serve DIN IEC 751 conversion table from °C to Ω!) and cali-

brate the signal conditioner output signal to 0.200 mA using

the null potentiometer. (The potentiometers are located be-

hind the hinged cover).

4. Set the "maximum" selected temperature on a PT 100 simu-

lator (or precision resistance decade) and calibrate the signal

output to 20.000 mA using the Span potentiometer.

5. Repeat steps 3 and 4 (approx. 2-3 times), until the required

accuracy is achieved.
