Purpose: To change the display from lb/min. to kg/min. by pressing the B key.

C) Auto Zero on/off

Purpose: To activate or deactivate the auto-zero function. The auto-zero routine will establish

zero output voltage automatically thus accommodating minor output signal voltage changes

that occur with time or temperature.

Function: To turn auto-zero function on or off press “C” repeatedly.

Auto-zero on:

When the valve is not enabled: The unit will automatically establish a zero output signal un-

less the sensor detects a signal greater than 10%. This identifies an abnormal end-of-cycle

condition indicating possible malfunction, such as a sensor not purging at end of a cycle.

When the valve is enabled: The unit will hold its last established value. Auto-zero off disables

this feature.
