6.1.8 Flow Calibration (1-point).
Your DLC is factory calibrated at rated flow and pressure (1-point). Nevertheless, you should always
perform a calibration with the PULSAR DLC installed in your system. The only item required to
calibrate your DLC is a means to measure the output of the pump (i.e., calibration column, graduated
cylinder, etc.). The following is a minimal procedure for performing a 1-point calibration.
1. Press [MOTOR] to start the motor (if the motor is not currently running).
2. Press [UNITS] repeatedly until a unit that is consistent with your flow measurement device (i.e.,
calibration column) appears. For example, if your column reads in Gallons then set the display to
GPM or GPH. Gallons will be used in this example.
3. Press [CAL]. The {CALIBRATE / PUMP FLOW} screen is displayed.
4. Press [ENTER]. The {LAST FLOW CAL / 11:32 1/22/01} screen is displayed.
5. Press [ENTER]. The {FLOW CALIBRATION / 1-POINT} screen is displayed.
6. Press [ENTER]. The {CALIBRATE ZERO? / YES} screen is displayed.
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 10.
7. 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.
8. 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. The DLC will
adjust the stroke to the 0% position.
9. The {PLEASE WAIT / XX% 100%} screen is displayed. The DLC will adjust the stroke to the
100% position. The PULSAR motor will shut off.
PLEASE WAIT
XX% 100%
10. The {ENTER TO START/ 100% 2.641718 G} screen is displayed. The value '2.641718'
represents the amount of fluid discharged over 60 seconds the last time a calibration was performed
at the 100% stroke setting. Record the fluid base reading from your calibration column.
11. Press [ENTER]. The PULSAR motor will start to run. A timer is displayed counting down from
60 seconds. After 60 seconds the motor will stop automatically.
TIMER: XX SEC
2.641718 G
12. The {ENTER VALUE 100% / 2.641718 G} screen is displayed. Calculate the measured volume
displaced from the calibration column and enter the new value one position at a time using [UP]
and [DOWN] to change an individual position. Press [ENTER] to move the cursor to the next
position.
13. Pressing [ENTER] on the last position will cause the {CONFIRM CHANGE? / YES} screen to be
displayed. Press [ENTER] to accept. Your 1-point calibration is now complete.
Refer to Section7 – General Operation: Calibration, Pump Flow for more detailed instructions on
how to perform DLC calibration.
