Option: External
5.2.6.6.
Useful reasons for the function of external ambient temperature:
1. Changing ambient conditions may be measured permanently to compensate their effects.
2. Decoupling compensated temperature from internal temperature of cooled instruments.
3. Measurement of a reflected reference area to improve uncertainty.
To read in external ambient temperature, analog input is adjusted in such a way that a signal 0-10 V is
analyzed in proportion to temperature range. Value LOW corresponds to 0 V, value HIGH corresponds to
10 V input signal.
