ENABLE AUTOMATIC CALIBRATION FEATURE
The VRF-1000 is shipped form the manufacturing facility with the EZ-CAL™ II feature disabled (OFF).
If automatic calibration/recalibration is desired, set the SW1 DIP switch position 6 to ON. When
enabled, the unit will automatically recalibrate whenever it senses a lower capacitance than the
previously calibrated point. Sensing only air, or a lower material level than previous sensed, will initiate a
recalibration.
Note
Conductive or excessive material build-up on the Pro-Guard section of the probe will cause the probe to
recalibrate to a lower than normal point. DO NOT turn this feature on if excessive build-up is likely.
This unit can also be manually calibrated by pressing the recalibration push button. See Figure 4.1. The
probe must not have material level present when calibration is performed.
