DEF fluid tends to dissipate air much slower than for gasoline or diesel fuel. Wait for
three minutes and gently tap the prover can with a rubber mallet to ensure entrapped air
is dissipated and an accurate reading can be taken.
IMPORTANT INFORMATION
Dispense fuel into the prover can exactly to the zero mark. The uncalibrated volume appears.
Notes: 1) If the fuel/DEF is not dispensed within four minutes (about) of switching on the
pump handle (or within the time period set by the controller for pulsar time out), the
error code 574 appears indicating that the pump handle must be switched off to
clear the error. Scrolling will resume after you replace the nozzle.
2) If the fuel/DEF dispensing has started but stopped and the pump times out, the
calibration switch must be turned to off position. Otherwise, error code 993 appears
as shown in
(99 indicates that the product is not available and 3 indicates
the product is not calibrated). The procedure must then be restarted from step
on
.

Switch off the pump handle and return nozzle to boot. After three seconds, the calibration
factor appears on the display for three seconds and then zeros are displayed indicating that the
meter is now calibrated. No further transactions will be allowed until the calibration switch is
turned to off position.
Note: If an additional transaction is attempted, error code 994 appears (99 indicates product
not available and 4 indicates calibration mode error). Turn the calibration switch to off
position and switch off the pump handle to clear the error. The error code 993 appears
indicating that the calibration procedure must be restarted from step
.
