10. When you are ready, press [ENTER], which will start the pump motor for a period of 60 seconds. The
screen will show a 60 second timer and display its count down toward 0 seconds. During this time, the
pump is operating at the designated stroke length setting and 100% motor speed.
TIMER: 60SEC
2.641718 G
If you already know the displaced volume, you can bypass the 60 second timer by pressing [UP]
and [DOWN] simultaneously.
11. At the end of 60 seconds, the pump motor will automatically turn off. The display will automatically
change to prompt you to enter the new measured flow rate.
ENTER VALUE 100%
2.641718 G
Read the new measured flow from the calibration column. Enter the new value one position at a time
using [UP] or [DOWN]. Press [ENTER] to accept each digit setting and move the cursor to the next
position. Continue to use the arrow keys and press [ENTER] on the last position to accept your setting.
If you make a mistake entering the measured flow rate and realize it before pressing [ENTER] on
the last position, press [UP] and [DOWN] simultaneously and the cursor is returned to the first
digit.
If you would like to "skip" a calibration point, enter a value of 0.
Any measured volume which translates to less than 10% of the maximum rated flow of the pump
should be disregarded from the calibration routine. To do this, enter a value of 0.0000.
12. If a 2 through 5 point calibration was selected, the DLCM will automatically proceed to the next stroke
length setting and repeat steps 9, 10, 11, and 12 as described above. After the DLCM has completed
the above referenced process for all stroke length settings, it prompts you to accept the data collected in
the above referenced steps:
CONFIRM CHANGE?
YES
13. Press [ENTER] to accept the calibration. The DLCM will display a {PLEASE WAIT} message while it
performs the Least Squares curve fit to the data points and calculates the new flow curve. Any point
entered with a value of 0.0000 will be ignored by the curve fitting routine.
If you do not want to accept the new calibration, press [UP] to scroll to {NO} and press [ENTER].
The display is then returned to its original operating mode.
