Calibration
Basic Calibration:
With the fluid tank empty, enter the
calibration password.

The left (0%) bar will flash to indicate
that you are ready to calibrate for an
empty tank.
Activate the right switch followed by
the left switch.
The right (100%) bar will flash to in-
dicate that the display is ready to cal-
culate for a full tank.
When the tank is full, actuate the right
and then the left switch.
Calibration is complete.
If after checking the accuracy of your
calibration, you are not satisfied, then
you can perform the advanced cali-
bration procedure. This is rarely nec-
essary except in the case of oddly
shaped tanks.
Advanced Calibration:
With the fluid tank empty,
enter the calibration password.

NOTE: Calibration is based on
the weight of the column of water
immediately above the transducer.
If the unit is calibrated with a water
level that is temporarily higher
than normal, this will result in an
inaccurate display.
