CALIBRATION
TFFT02814
NOTE
This calibration procedure must be performed when installing a new foam level probe or
foam level gauge.
Both foam level probes are calibrated the same way.
1.
Measure distance between baseline of foam level probe (1) and top (full) of foam level probe (1).
2.
Divide distance measured in Step (1) by two, and mark middle line - 1/2 full on foam level probe (1).
3.
Measure distance between middle line - 1/2 full and baseline on foam level probe (1).
4.
Divide distance measured in Step (3) by two, and mark 1/4 line.
5.
Measure distance between middle line - 1/2 full and top (full) on foam level probe (1).
6.
Divide distance measured in Step (5) by two, and mark (3/4) line.
