Electronic Calibration (E-CAL) Adjustment for E-85/DEF Unit
After five seconds, the prover can size appears in the two Least Significant Digits (LSD),
right-most digit of the pump display (see
). The can size will appear for five seconds
before advancing to the next can size. The display will continue to scroll through can sizes
until the nozzle is removed and pump handle is switched on.
Note: If the nozzle is not removed within 10 minutes of turning the switch to calibrate position,
error code 574 appears (57 indicates time out and 4 indicates calibration mode error).
Turn the calibration switch to off position (down) to clear the error.

begun, switch off the pump handle, turn the calibration switch to off position, and
restart calibration from step
