How to Calibrate your tank using the FINCH II display?

Understand the difference between manually calibrating your system through the FINCH display and just entering into CAL Mode on your system.

FINCH II Calibration

With the FINCH II display it is possible to put the display into CAL mode using 2 different methods.

1.   Power on your TD System.

2.   Choose the compartment that you want to calibrate.  

Option 1:

The easiest way to initiate CAL mode in the FINCH II is to hold down the four function buttons on the display front.

3.   Press and hold the four gray buttons on the display until CAL starts to flash on the display. 

• COMP SELECT
• HORN BYPASS
• ACK
• DIM SLEEP 

Hold and press the buttons simultaneously until the word CAL is displayed on the FINCH II. Release the buttons.

Option 2:

1. Power off your Titan System. 
2. While your system is powered off, press and hold one of the arrow buttons. It doesn't matter if it is the up or down button. 
3. While continuing to hold down the arrow button, power on the system. This will require two people if the FINCH requires the vehicle to turn on to power it.
4. Continue holding down the arrow button until the word CAL is displayed.
5. Release the arrow button.

Your tank must have at least 6 inches of liquid in the compartment you require to calibrate. 

Press the Up or down arrows to show the volume you want to change this to. 

Place the system into CAL mode and then adjust the display using the arrow buttons up or down to match the same volume as the liquid in the tank.

CAL Mode

There are some cases where just entering into Calibration Mode, without calibrating your volume settings, will adjust your system to normal level measurements.

The following steps are used as a troubleshooting process to help reset any alarms or address issues with your system. 

1.   Power on your TD System.

2.   Choose the compartment that is triggering the alarm or issue. 

On the FINCH II display, the compartment number appears to the left of the red 5 digit display. The example below shows Compartment 1 is stuck in Spill. 

3.   Press and hold the four gray buttons on the display until CAL starts to flash on the display. 

• COMP SELECT
• HORN BYPASS
• ACK
• DIM SLEEP 

4.   Release all the buttons when CAL starts to flash on the display.

5. Wait for the display to show a volume. 

6.   Once the volume is showing on the FINCH display, you can then power off your TD System and then power it back on.

This process should return your system to normal level measurements.
