Operating Mode; Functional Description - Chauvin Arnoux Statop 4849 Manual De Instrucciones

Proper sensor type is also a very important factor in obtaining precise measurements. The sensor must
have the correct temperature range to meet the process requirements.
Controller accuracy is far greater than, and therefore limited by, the input sensor.
