The TM20 can display and record voltages from a sensor that can output a voltage
signal of
±
100 mV or
±
1 V (provided that a U-shaped connector is used and the
connector and the temperature input jacks are stabilized at the same tempera-
ture).
6.1
Available ranges
A measuring range can be chosen from ther-
mocouple types K, J, E, and T, and 1 V and
100 mV.
