3.2.2.3 Calibration and Defaults
Change Calibration
The TCIC is factory programmed with the value of the on board
reference voltage (1.25V). However, this default 1.25V value may be
re-defined in the range 1.2375V to 1.2625V, that is 1.25V ±1%. In
order to find out the voltage, use a high resolution DVM (at least 5.5
digits), and measure between ‘GND’ and ‘COM’ in the screw terminal
(CONN1 or CONN2). Click ‘Change Calibration’ and enter your
measured new value.
Reset to Factory Default Values
You may return the card to its initial factory settings:
•
All channels set to voltage reading (Input Type = mV).
•
Temperature Unit: ºC.
•
All Output Modes: Manual.
•
All Setpoints (both ‘switch on’ and ‘switch off’): 0.
•
Reference Voltage: 1.25V.
•
Card Filter Level: Standard.
