Example: L = 12” (30 cm) from the bottom of the tank
H1 = 72” (183 cm) from the bottom of the tank
H = 96” (244 cm) from the bottom of the tank
( 72 - 12 )
mA = -------------- x 16 + 4 = 15.43
( 96 - 12 )
The correct loop current is is 15.43mA.
Depress SPAN S-UP or S-DW buttons as required to
obtain a meter reading of 15.43mA. If 15.43mA reading
has been obtained, the calibration is complete.
Note: If a 15.43mA value cannot be reached, then
peform OFFSET AND RESET functions and re-start the
calibration
