4.4.16.3. Calibrating temperature sensor
Description
The resistance of the wedge temperature measurement can be calibrated as follows.
(Setting contents)
Calibrate: Calibrates resistance value 100
Ω
(wedge temperature: 0
°
C) and resistance value 140
Ω
(wedge temperature: 100
°
C)
Clear:
Displayed under uncalibrated state or when calibration error has occurred.
(The uncalibrated state cannot be restored after calibration.)
Note: Temperature sensor specifications
Measurement range:
−
40 to 100
°
C
Sensor:
Built into resistance bulb for wedge temperature measurement
Built-in resistor:
JIS C1604, Class B or equivalent
Transformer:
Built into resistance-temperature conversion circuit
Connection: 3-wire
Connect a resistor to temperature sensor terminals as shown below.
