You can "skip" a calibration point by entering a flow value of 0.0000. “Skipping” a point means that
it will be omitted from the mathematical regression to establish the flow curve. Values which are less
than 10% of the pumps’ rated output flow should be skipped.
4. Press [ENTER]. The {CALIBRATE ZERO? / YES} screen is displayed.
CALIBRATE ZERO?
YES
Press
[ENTER]
If you are confident with the quality of your zero calibration, press [UP] and the {CALIBRATE
ZERO? / NO} screen is displayed. Press [ENTER] and continue with step 8.
5. Press [ENTER]. The {TURN MOTOR ON / TESTING ENCODER} screen is displayed, or if the
pump motor was ON when you started the calibration process, the {PLEASE WAIT / TESTING
ENCODER} screen is displayed.

6. Turn the pump motor on if necessary and the encoder performs its self test. When the self test is
completed, the{PLEASE WAIT / CALIBRATING ZERO} screen is displayed.
PLEASE WAIT
CALIBRATING ZERO
7. The DLCM will now perform a ZERO CALIBRATION. First, it will turn on its motor and adjust its
speed to 100%. Then it will test the encoder's position by increasing the stroke adjustment mechanism
2%. Then the DLCM will adjust in the opposite direction until it reaches the mechanical zero stop (0%
stroke setting). This ensures that the positioning mechanism is working properly and calibrations will
be accurate. The screen will display one of four messages:
PLEASE WAIT
CALIBRATING ZERO
- or - TURN MOTOR ON
TESTING ENCODER
PLEASE WAIT
MOTOR CAL.
- or - ENCODER ERROR
PRESS ENTER
If the {TURN MOTOR ON…} screen is displayed, start the PULSAR motor by pressing [MOTOR].
The DLCM will adjust to the 100% position. If you get the {ENCODER ERROR..} screen, refer to
Section 11 – Trouble Shooting Guide.
8. The following screen is displayed.
PLEASE WAIT
XXX.X% 100%
If you get the {PRESS ENTER / TO START MOTOR} screen, start the PULSAR motor by pressing
[ENTER] or [MOTOR].
The XXX.X% represents the current stroke length adjustment setting and 100% is the stroke length
destination.
9. Once the destination setting has been reached, the PULSAR motor will shut down and the display will
show:
ENTER TO START
2.641718 G
The display is showing the amount of fluid discharged from the pump the last time this operation was
performed (e.g., 2.641718 Gallons). This flow rate is based on 60 seconds of pump operation. Fill the
calibration column in the system to the proper level to avoid running the pump dry during
calibration.
