TASC Error 0


The TASC console displays the message Error 0 when attempting to spray.

Definition of Problem

An Error 0 condition indicates one of the required calibration numbers the TASC uses to calculate pump demand is set at 0.


Change the TASC mode switch to Setup. Turn the display rotary switch to the following positions and review the calibration numbers displayed. Use the Increase / Decrease switch to adjust the calibration number as required. We have listed the most common calibration numbers below for your reference.
