T
Selecting T will enable the instrument to operate in constant temperature mode
when OUTPUT is turned on. In T mode, the controller output current to the TEC is
continuously adjusted to maintain the setpoint temperature at the sensor. Any of
the sensor types (thermistor, RTD, IC-I, IC-V) can be used in this control mode.
Auto-Tune and user selectable PID constants are active in this mode.

TEC is continuously adjusted to maintain the setpoint sensor resistance
(thermistor, RTD), current (IC-I) or voltage (IC-V). Auto-Tune and user selectable
PID constants are active in this mode.
