Input for Connection of a Resistance Thermometer

This input is designed to connect a PT 100 resistance thermometer. The mapping curve, R = f(T), of PT 100 resistance thermometers is defined in the IEC 751 standard. If the PT 100 resistance thermometer is connected using the 3-wire method, then no further calibration is required.

Open-Circuit Monitoring

If there is an open measuring circuit due to a broken wire, the signal SFMON: PT100 open circuit is issued.

Maximum Temperature Value Since the Last Reset

The result of a temperature measurement cannot only be read out as a direct measured value (temperature T) or as a normalized value (temperature norm. T), but also as the maximum value since the last reset (temperature Tmax).

For this the following menu points are available:

▪	MEASI: Temperature Tmax (maximum temperature value)
▪	MEASI: Reset Tmax EXT (reset via a binary signal)
▪	MEASI: Reset Tmax USER (manual reset)
