2.10.2 Using ThePoint with Auto-Calibration mode #2
After ThePoint is installed in the vessel, simply apply power.
ThePoint electronic unit will auto calibrate.
Caution
The material being measured must be below the sensing element
when power is applied (Sensing element uncovered).
Note:
If power has been applied to ThePoint prior to installation (on a
test bench) or, if ThePoint is moved from one vessel to another,
RECAL is necessary. RECAL allows the system's software to
capture the air capacitance generated by the sensing element
in tank.
Merely press and hold the RECAL button (shown in Figure
2-6) for ve (5) seconds. After ve seconds, ThePoint's two
LED’s ash for sixty seconds before the recalibration occurs.
(Removing power from the system while the LED's are ashing
will reset the memory immediately upon next power up).
Calibration is complete.
