6.1.11 Calibration (1-point).
Your DLC-XP/RC is factory calibrated at rated flow and pressure (1-point). Nevertheless, you
should always perform a calibration with the PULSAR DLC-XP/RC installed in your system. In
addition, a flow calibration will confirm that the DLC-XP is communicating properly with the DLC-
RC. The only item required to calibrate your DLC-XP/RC 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. Refer to Section 7 – General Operation: Calibration, Pump Flow
for more detailed instructions on how to perform a DLC-XP/RC calibration.
Fluid compressibility will drastically influence the accuracy of a 1-point calibration. The user is
advised to perform a multi-point calibration.
1. Press the [MOTOR] key to start the motor (if the motor is not currently running).
2. Press the [UNITS] key 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 the [CAL] key. The {CALIBRATE / PUMP FLOW} screen is displayed.
4. Press [ENTER]. The {LAST FLOW CAL / 21:32 4/26/00} screen will appear.
5. Press [ENTER]. The {FLOW CALIBRATION / 1-POINT} screen will appear.
6. Press [ENTER]. The {PLEASE WAIT / CALIBRATING ZERO} screen will appear. The DLC-XP
will adjust the stroke to the 0% position(*).
7. The {PLEASE WAIT / 14% 100%} screen will appear. The DLC-XP/RC will adjust the stroke to
the 100% position. The PULSAR motor will shut off.
8. The {ENTER TO START/ 100% 1.3642} screen will appear. The value '1.3642' represents the
amount of fluid discharged over 60 seconds the last time a calibration was performed at the 100%
stroke setting. Record the base reading from your calibration column.
9. Press [ENTER]. The PULSAR motor will Start to run. A timer will display counting down from 60
seconds. After 60 seconds the motor will stop automatically.
10. The {ENTER NEW VALUE / 100% 1.3642} screen will display. Read the calibration column and
enter the new value one position at a time using the [UP] and [DOWN] to change an individual
position. Press [ENTER] move the cursor to the next value.
11. Pressing [ENTER] on the last value will cause the {CONFIRM CHANGE? / YES} screen to appear.
Press [ENTER] to accept. Your 1-point calibration is now complete.
(*) If during the {PLEASE WAIT / CALIBRATING ZERO} display (step 6) you obtain the
following message: {ENCODER ERROR ## / PRESS ENTER} then one of two conditions is causing
this error: 1) the DLC-XP is not powered or 2) the control wiring between the DLC-RC and DLC-XP
is incorrect.
Refer to Section 7 – General Operation: Calibration for more detailed information on calibration
features and procedures.
6.1.12 Wrapping up.
Your PULSAR DLC-XP/RC is now commissioned for manual use. Refer to Section 7 – General
Operation for specific instructions on how to access your DLC-XP/RC's advanced features. Don't be
intimidated by your DLC, take time to explore and experiment with its features. You cannot
configure the software in a way that would damage the DLC-XP/RC. Whenever you are about to set
a critical value (e.g., Calibrate Flow), you are always prompted to confirm your change before it takes
effect. And if you are ever dissatisfied with the configuration of your DLC-XP/RC, you can always
return to the Factory Defaults by repeating Section 6.1.7.
