3 Features and Functions
Temperature
This section describes how to configure the selected channel for temperature measurements from the front panel.
Temperature measurements require a temperature transducer probe and the supported probes are thermocouple,
thermistor and resistance thermometer (RTD).
Thermocouple
1. Connect a thermocouple to the module's screw terminals.
2. Press [Channel] > Measure, and select TEMP from the selection menu.
3. Press the Units softkey to specify the temperature measurement units as °C (Celsius), °F (Fahrenheit), or K
(Kelvin). You can mix temperature units on different channels within the instrument and on the same module.
4. Press Sensor Settings > Sensor, specify the type of transducer probe used as TCouple, and press Type softkey
to select the type of thermocouple. Supported types are J (default), K, E, T, N, R, B, and S.
5. Press Integrated Settings softkey to select whether the measurement integration time will be specified in terms
of Number of Power Line Cycles (NPLC) or directly in seconds (Time). Only 1, 2, 10, 20, 100, and 200 PLC
provide normal mode (line frequency noise) rejection. Selecting 200 PLC provides the best noise rejection and
resolution, but the slowest measurements.

Description
Sets the integration time as 0.001, 0.002, 0.006, 0.02, 0.06, 0.2, 1, 2, 10, 20, 100, and 200 Power Line
Cycles (PLC). Only 1 PLC and longer times provide normal mode (line frequency noise) rejection.
Selecting 100 or 200 PLC provides the best noise rejection and resolution.
Directly sets the integration time in seconds.
