Working with the P-CHK Function

Overview

The P-CHKfunction (Pressure Check Function) (Page 17) is useful to a service technician for troubleshooting a flow fault problem. The monitor will trigger a flow fault if the pressure drop from ambient is less than 0.2 psi during a purge cycle, and 0.5 psi during a measurement cycle.

Keypad Functions

The Left Arrow Keypad button toggles the purge valve open and closed. Note that an asterisk (*) appears when the purge valve is open (purging).

The Down Arrow Keypad button toggles the pump ON and OFF.

Pressing the ENTER button stores the current manifold pressure shown on the left to the ambient pressure shown on the right (must be done with the pump OFF).
