7. General Operation
This section covers the General Operation of the DLC as it relates to software. It includes detailed
instructions and example screens to aid the user. The default values of the DLC have been factory set.
The user can over-ride these settings to tune the DLC to his/her particular needs.
7.1 Calibration
The DLC can be calibrated for Flow, Analog Input and Analog Output. You should perform calibration
on all three parameters (or any that are to be used) upon installation of the PULSAR DLC into your
system.
If no keys are pressed for 5 minutes during the calibration sub-menus, the present input will be
aborted and the original screen will return.
7.1.1 Pump Flow Calibration
Pulsafeeder recommends performing at minimum a 1-Point flow calibration on every PULSAR DLC
installed. Maintenance re-calibration should be performed periodically -- at least every three to four
months -- to account for component wear. Re-calibration of the pump is also recommended
whenever wet-end components are replaced.
1. Press [CAL] to enter the Calibration Menu. If the screen {CALIBRATE / PUMP FLOW} is not
displayed, press [UP] until it appears. Press [ENTER] to go to the calibrate pump flow sub-menu:

PUMP FLOW Press
[ENTER]
2. The DLC displays the last time the pump was calibrated. This provides a key record for the user.
Press [ENTER] to continue with pump flow calibration.

3. The display shows {FLOW CALIBRATION / 1 POINT}. The '1 POINT' text will be flashing
FLOW CALIBRATION
1 POINT
Press
[UP]
Press [UP] to change the flow calibration to 2 points, 3 points, 4 points or 5 points. The calibration
points correspond to the following stroke length values:
1 point 100%
2 points 10 and 100 %
3 points 10, 50 and 100%
4 points 10, 25, 50 and 100%
5 points 10, 25, 50, 75 and 100%
These percentage values correspond to the API standard. If you continue to press [UP] you will also
see the following options: {CHANGE CONSTANTS} and {TUNE}. These options are for use after
a multi-point calibration has been performed. They are explained in more detail in steps 4 and 5
below. For a standard multi-point calibration, set the number of calibration points to use and press
[ENTER] to continue. Skip 4 and 5 below. Proceed to step 6.
