Entering the Coil Factor

 

The Coil Factor for the wire coil is used in calculating Carbon Potential and is based on variations in coils in a batch. The recommended Coil Factor is printed on each bag of coils and is the same for all coils in a batch. Before using the coil in the testing process, follow this procedure for entering and verifying the Coil Factor. It is essential that this procedure be followed correctly.

First, note the recommended Coil Factor printed on the bag of coils that the coil you are using came from. If you do not have the bag, assume a Coil Factor of 100.

 

Next, log in with Configuration Mode on the CAT-100 by following these steps:

 

 

From the main status screen, push the menu button.

 

 

Figure 4 - Main Status Screen

Open the Detail menu from the main menu. The Detail screen will be shown, and the Coil Factor will be displayed in a box labeled “Factor”. Tap on that box to continue.

A numeric entry screen will appear. Enter the Coil Factor that you noted earlier for the wire coil (or enter 100 if you do not have the Coil Factor available).

The Detail screen will now show the Coil Factor that you entered.

Return to the CAT-100 main status screen.

 

Attach the wire coil to the binding posts using the small holes on the sides of the posts, as illustrated in Figure 8 and Figure 9. Make sure to tighten the binding posts by turning each screw clockwise; do not overtighten. Also, do not allow the coil to make contact with the external thermistor.

Note: The CAT 100 coils are not compatible with carbonitriding processes.

 

Once the coil is attached to the binding posts, note the %Carbon displayed on the CAT-100.  The % Carbon should be as close as possible to the carbon potential listed on the bag.   In order to increase the %C, increase the Coil Factor. In order to decrease the %C, decrease the Coil Factor.
