Calibration
Ensure that the fail-safe jumper is installed in the proper
position as described in Table 1. The LED will show
red when in alarm condition and green when in normal
condition. Test the operation of the switch by holding,
and then releasing the vibrating rod; the LED will
change color.
The sensitivity of the switch can be changed using the
density adjustment screw. Note that this adjustment screw
has 270 degrees of rotation. Do not rotate past the stops.
NOTE: If the adjustment is too sensitive, the switch may detect
even slight residue of material rather than level.
Prior to installation, it is recommended that the unit be
calibrated using a sample of the media to be measured.
