R (O) - the resistance of the sensor in ohms.
S (O/K) - the sensitivity of the sensor in ohms per Kelvin.
T (K) - the temperature measured by the sensor in Kelvin.
V (mV) - the sensor excitation voltage in mV.
2 Tap the Sensor Type parameter box and select a sensor type from the drop-down menu.
Sensor types include
(a) thermocouple
(b) PTC - positive temperature coefficient sensor
(c) NTC - negative temperature coefficient sensor
(d) Diode
A detailed description of sensor types in given in section 4.11.
3 Tap the Calibration parameter box and select a calibration file from the drop-down menu.
The list of files available depends on which sensor type is selected. If you select a Generic
calibration file, you can later adjust the calibration to suit a particular sensor (see section
4.10).
4 Interpolation
Linear interpolation is used to calculate the calibration curve from the calibration table.
5 Tap the Excitation parameter box and select an excitation mode from the drop-down menu
(see section 4.11.5).
6 Tap the Magnitude parameter box and enter an excitation value using the numeric keypad:
(a) If Sensor Type is set to PTC, enter an excitation current in µA.
(b) If Sensor Type is set to Diode, enter an excitation current in µA.
(c) If Sensor Type is set to NTC, enter an excitation voltage in mV.
(d) If Sensor Type is set to Thermocouple, this value is ignored.
Tap OK to accept the value and return to the Sensor Details page.
7 If desired, tap the parameter box containing the name of the sensor and enter a new name.
(e.g. Change DB3.T1 to Example).
8 Cal Adj
Tap once to access the Generic Sensor Adjustment page (see section 4.10.2). This allows
the user to adjust the scale and offset of a generic calibration curve to suit a particular
sensor.
