DISPLAY CALIBRATION

A. 

There are two calibration potentiometers on the back of Checkmate instrument. One 

potentiometer calibrates the To Process probe and the other potentiometer calibrates the 

other probes (From Process, To Tower, From Tower).

B. 

The procedure described here avoids the necessity of removing any of the probes from 

the pipes or manifolds. It requires that you are able to independently determine the 

temperature of the water on the ‘Cold’ side of the system water tank. This is the side of 

the tank that receives cooled water from the tower cell.

C. Preparation.

1. 

You will need the following to complete the calibration procedure.

a. 

A small screw driver to adjust the potentiometers on the circuit board.

b. 

A temperature measuring meter with a probe long enough to be 

immersed on the system tank. 

2. 

Warning. The system must be powered to perform the calibration. Some of the 

components on the Checkmate controller board are connected to 110 VAC. 

Toughing any components (other than the potentiometers) carries the risk of 

serious electrical shock. Calibration should only be performed by a qualified 

technician. 

D. 

To Process Probe Calibration

1. 

Observe the temperature of the independent temperature meter. Ensure that it is 

stable.

2. 

Configure the Checkmate Display to show the To Process Temperature.

3. 

Adjust the ‘Probe Cal’ potentiometer by 1/4 turn. Wait 30 seconds for the 

adjustment to take effect.

4. 

Repeat step 3 until the temperature displayed by the Checkmate agrees with the 

independent temperature meter. 

Note: This potentiometer only affects the To Process temperature.

E. 

From Process Probe Calibration

1. 

Observe the temperature of the independent temperature meter. Ensure that it is 

stable.

2. 

Configure the Checkmate Display to show the From Process temperature.

3. 

Adjust the ‘All Other’ potentiometer by 1/4 turn. Wait 30 seconds for the 

adjustment to take effect.
