F4T Controller Calibration 

 

 

2

 CAUTION:

  Calibrating the F4T Controller requires the electrical compartment to be 

exposed. Live and potentially lethal voltages will be present. Use extreme 

caution to prevent injury and death. 

 

!

 CAUTION:

  The Power button on the F4T Controller must be OFF (no green check mark) 

when performing the calibration procedure to prevent a thermal runaway 

condition. 

 

Equipment Required 

 

 

Precision Resistance Source, 50.00 

 and 350.0 

 for Temperature Sensor. 

 

Precision Milliamp Source, 0.000 mV and 20.000 mA for Humidity Sensor. 

 

Precision Voltage Source, 0.000 mV and 50.000 mV for Limit Sensor. 

 

Input Setup and Calibration 

 

Make sure the Power button on the F4T Controller is OFF (no green check mark) before 

performing the following. Disconnect the chamber from the power source and remove the top 

cover. See F4T diagram on the next page for the terminal locations. 
 

For Temperature Sensor Input Calibration 

 

Remove the wires from terminals R1, T1 and S1 on F4T Slot 1 

 

Connect the Precision Resistance source as follows: 

One lead to R1 on Slot 1 

Other lead to T1 and S1 on Slot 1 

 

Reconnect the chamber to the power source and turn the Power switch on the front panel ON. 

The Power button on the F4T must remain OFF.  

 

To enter the Calibration menu, press the Menu button, then the Service button, then the 

Calibration button, then the Temperature Sensor “Actions” button. Next, press Perform Field 

Calibration and follow the on-screen prompts.  

 

For Humidity Sensor Input Calibration 

 

Remove the wires from terminals T1 and S1 on F4T Slot 4. (T1 is Red and S1 is Black) 

 

Connect the Precision Milliamp source as follows: 

+ lead to T1 on Slot 4 

– lead to S1 on Slot 4 

 

Reconnect the chamber to the power source and turn the Conditioning switch (or TEMP 

switch depending on which model chamber you have) on the front panel to the Event 1 

position. The Power button on the F4T must remain OFF. 

 

To enter the Calibration menu, press the Menu button, then the Service button, then the 

Calibration button, then the Humidity Sensor “Actions” button. Next, press Perform Field 

Calibration and follow the on-screen prompt.
