Battery Selection Buttons
The Batt ery Selection Butt ons (Figure 7) allow the
user to select the battery that is installed in the
sample pump. Check the label on the batt ery pack,
and then click the butt on next to the appropriate
batt ery Part No. Selecting the proper batt ery ensures
that the pump indicates accurate batt ery status.
Flow Calibrate Buttons
The Flow Calibrate butt ons (Figure 8) are used to
apply a correction to the pump fl ow rate during
calibration to a primary standard
Controls Function
 ................................increases correction of pump
fl ow rate
 ................................decreases correction of pump
fl ow rate
Reset ..........................zeroes the value in the Approx
Correction cell
Comm Checking .....turns the communication
checking function on or off . This feature allows the user to
unplug a pump and plug in another pump without causing a
communication error.
Adjusting the Approximate Flow Correction
The Leland Legacy pump should be calibrated before each sample run.
1. Click the Reset butt on to reset the correction value to 0.00 L/min.
Changing the pump fl ow sett ing will also reset the correction value to
0.00 L/min.
2. Turn on the pump and connect the inlet port of the pump to a primary standard
calibrator. Read the fl ow displayed on the calibrator.
3. Click on the  or  butt ons in the Flow Calibrate window until the calibrator
displays the desired fl ow rate.
When adjusting the correction, the fl ow rate displayed on the calibrator changes,
the fl ow rate displayed on the pump does not change. The range of fl ow correction
is ± 2.5 L/min.
4. Repeat calibration aft er sampling to verify fl ow.
Example: The desired fl ow rate is 10 L/min.
