View source for TDA204 Utility on the T10

On version 5.3.4.37 of the APU102 application and below, the null values must be calibrated manually.&nbsp;&nbsp;

As depicted in the picture below, there are two Null Values to be calibrated: one for the WDA, and the other for the WDB.[[image:img1736988148633.png|624px|center|frameless]]

To adjust these two values, login to the supervisory menu. Enter the &lt;TDA204&gt; command to launch the TDA204 Utility. The unit can still be calibrated using the ”C” command, but the null values will need to be adjusted manually. To adjust the null values, use the 1 and 2 keys for WDA, and the 3 and 4 keys for WDB. Appropriate values are in the range of 32 – 42.
