Com ma nd Reference
The SENsor commands selects the sensor type and sense current.
One <character data value> representing the sensor type is required. The values
accepted are THERM10UA, THERM100UA, THERM1MA, ICI, ICV, RTD10UA,
RTD100UA, or RTD1MA.
For thermistor or RTD sensors, a sense current is applied through the sensor, and the
resulting voltage is measured by the instrument. The measured voltage range is 0-6V.
The best sense current to use depends on the expected resistance at the setpoint. The
largest possible voltage swing in the vicinity of the setpoint will result in the best stability.
For more details regarding proper sensor selection and sense current, refer to Chapter 2.
SEN THERM100UA action: sets the sensor to thermistor and the sense current to
100 µA.
The SENsor? query returns the selected sensor type and sense current (if appropriate).
The response is a single character string that represents the selected sensor and is one
of the following:
THERM10UA, THERM100UA, THERM1MA, ICI, ICV, RTD10UA, RTD100UA, or
RTD1MA.
SENsor? Response: ICI, means the ICI sensor is selected.
The SET: command path is used to access the control mode setpoint commands and
queries.
