Temperature Measurement
Background
The GDM-8261 can measure temperature using either
thermocouples or RTD sensors. For thermocouples, the
GDM-8261 accepts a thermocouple input and calculates
the temperature from the voltage fluctuation. The
thermocouple type and reference junction temperature
are also considered.
For RTD sensors, the GDM-8261 calculates voltage
based on the resistance of the chosen RTD.

Connect the sensor lead between the V and the COM
port for thermocouple and 2W RTD measurements. For
4W RTD measurements, also connect the sense HI and
LO ports to the sensor. The display updates the reading.
