4.4. PT100 Temperature Sensor Calibration
The PT100 temperature sensor can be connected to measure and control the heated liquid temperature. The sensor has
been initially calibrated in the factory. If the measured temperature is slightly different from the temperature standard you
are using, a follow-up calibration is also possible with the following steps.
Calibration Procedure
Plug the PT100 temperature sensor into the designated input and turn
on the main power switch
Put the PT100 sensor and third-party thermometer in the temperature
environment of T1, T1 means the first measured temperature point for
calibration (e.g. 300 ml silicone oil, the temperature 1 stability at 24
degree, this value should be measured by the third-party thermometer)
e.g. the digital display shows “S1”
Press the CLEAR Button 10 times to enter the calibration mode (You
have reached the calibration mode when all LED lights light up and the
digital display shows “S1”. “S1” means Set 1 (The first setting
temperature for calibration).
e.g. TI Set to 24
Wait for the “T1” to reach and equilibrium(24
℃
)
refer to the shows value on third-party thermometer and Press Up
Button and Down Button to set the actual value of T1 (e.g. Set to 24 )
e.g. The corresponding AD value of S1
is 429
now the display shows its corresponding AD read value of S1
Press and hold the START / STOP Button and observe the value change
on the display
Release the START / STOP button when the temperature fluctuation is
less or equal to ±1
Press the SELECT Button on the operation panel. The display will shows
“S2”. “S2” means Set 2 (The second setting temperature for
calibration).
Put the PT100 sensor and third-party thermometer in the temperature
environment of T2, T2 means the second measured temperature point
for calibration (e.g. 300 ml silicone oil, the temperature stability at
151 degree, this value should be measured by the third-party
