6.1.8 Flow Calibration (1-point).
Your DLCM is factory calibrated at rated flow and pressure (1-point). Nevertheless, you should
always perform a calibration with the PULSAR DLCM installed in your system. The only item
required to calibrate your DLCM 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 Liters then set the display to
LPM or LPH. Liters 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 DLCM will
adjust the stroke to the 0% position and the motor speed to 100%.
9. When the zero calibration is complete the {PLEASE WAIT / MOTOR CAL.} screen is displayed.
PLEASE WAIT
MOTOR CAL.
With the stroke set at 0% the motor will run at 100% for a few seconds, and then decrease speed to
5%.
It will take anywhere from approximately 10 seconds to 5 minutes to complete the speed change. If
your pump continues to run after 5 minutes there is an error and you should contact Technical
Services.
10. The {PLEASE WAIT / XX% 100%} screen is displayed. The DLCM will adjust the stroke to the
100% position. The PULSAR motor will shut off.
PLEASE WAIT
XX% 100%
11. 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.
12. 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
13. 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.
