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
observe DIN IEC 751 conversion table from °C to Ω!) and
calibrate the signal conditioner output signal to 0.100 V
using the null potentiometer. (The potentiometers are located
behind 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 10.000 V using the Span potentiometer.
5. Repeat steps 3 and 4 (approx. 2-3 times), until the required
accuracy is achieved.
4.3 Setting the DIP switches
Warning!! The signal conditioner PT 100 must be protected
against a direct electrostatic discharge when setting
the DIP switches.
