The Leland Legacy®dual diaphragm sample pump is designed specifically
to provide constant airflows from 5 to 15 L/min with minimum power
requirements and low noise. Diaphragm and valve design minimizes power
requirements and reduces noise. Incoming and outgoing airflow is pulsation
dampened. The lightweight Leland Legacy is housed in a thermoplastic
material for strength and features an overmolding of sorubber that protects
against damage and reduces noise. Powered by a rechargeable Li-Ion baery
pack, the Leland Legacy provides 24-hour run times at 10 L/min and 12 inches
water back pressure. The pump’s patented internal flow sensor measures flow
directly and acts as a secondary standard, constantly maintaining the set flow
rate. Built-in sensors automatically correct flow for variations in temperature
and atmospheric pressure. Advanced programming features are available when
used with a PC and DataTrac®for Leland Legacy Soware. The performance of
the Leland Legacy pump with the Sioutas Impactor has been verified through
EPA-ETV.

Pump Setup
Flow Rate and Volume Display
hFlow Rate displayed on the pump LCD is the flow to which the pump has been
calibrated. To maintain flow as displayed, the pump automatically adjusts flow
during sampling for changes in temperature and atmospheric pressure that may
differ from the temperature and atmospheric pressure present at the time of
calibration. The flow rate display does not change from the calibrated flow rate.
The pump will fault if it is unable to maintain the calibrated flow rate.
hVolume displayed on the pump LCD is “corrected” in that it is the result of a
continual calculation of corrected flow rate multiplied by sample time.

12
Verifying Flow Rate Using a Primary Standard Calibrator
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
1. Ensure the pump has run for 5 minutes before performing calibration.
2. Connect the pump inlet to a calibrator with representative media in line
(see photo below).
3. Press [ST], then press the security code ÒSTÒin sequence. The flow
rate and Set will flash.
4. Set the flow on the pump display by pressing Sor T
to increase or decrease flow to the desired rate.
5. Press Ò. Adj will appear.
6. If the calibrator reads a higher flow rate than the
pump is set for,
press Tuntil they
are in agreement
(within 10 ml).
If the calibrator
reads a lower flow
rate, press Suntil
they agree (within
10 ml). When
pressing Sor T,
the pump display
will indicate the
adjustment (or correction) made in L/min.
7. Press Òuntil End appears.

Verifying Flow Rate Using the CalChek Automatic
Calibration Feature
The CalChek automatic calibration
feature is available when calibrating
a Leland Legacy with a Defender
calibrator (Cat. No. 717-510H). A
CalChek Communication Cable
(Cat. No. 210-502) is required
for communication between the
pump and the calibrator. Optional
DataTrac for Leland Legacy
Soware can be used to expand
the documentation capabilities of
this feature. The CalChek feature
provides single-point calibration to set and verify flow at a single point before
and aer sampling and multiple-point (full) calibration to calibrate flow to a
primary standard at multiple flow rates within the pump flow range. Both
calibration options bring flow to within ± 5%.
For optimum accuracy, do not perform single-point or multiple-point
calibration until the pump has remained at ambient temperature for
several hours.
Single-point Calibration Using CalChek
The CalChek feature provides correction at a single flow seing and usually
takes less than one minute to complete. Use it to set the desired flow rate
before sampling and to verify flow aer sampling.
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
Calibrate with representative sampling media in line.
1. Ensure the pump has run for 5 minutes before starting calibration. Leave
the pump on.
2. Use two pieces of 1/4-inch tubing, one to connect the Defender suction
port to the inlet of the representative sample medium and the other to
connect the medium outlet to the Leland Legacy pump inlet.
3. Select the Defender data port:
a. Press and hold the Defender power buon to turn on the flowmeter.
b. Press the right arrow to highlight Setup; press Enter.
c. Press the right arrow to highlight Preferences; press Enter.
d. Press the down arrow to navigate to Data Port.

7. Press the security code ÒSTÒin sequence on the pump keypad to enter
Setup.
8. Set the pump to the desired flow rate.
9. Press Òon the pump keypad until CALCh appears on
the pump display.
Note: If “no” is flashing on the pump LCD, the pump
has not equilibrated. Wait until the “no” display
disappears before proceeding with calibration.
10. Press [ST] to initiate single-point calibration.
11. The Defender calibrator will begin to automatically
calibrate the pump. Initial flow measurements are
taken without flow from the pump and the pump flow
rate is adjusted automatically. The pump will display
1Cal. During calibration, the pump will briefly display
the flow rates that it is reading from the calibrator.
12. When calibration is completed, the Leland Legacy will
continue to run. If the calibration was successful, the
pump LCD will revert to displaying pump run time as
0.0. If there was failure during the calibration process,
an error code of E4[x] will appear (see CalChek Error
Chart on page 17).
Note: To remove a CalChek error code from the LCD, press Ò.
13. Place the pump in Hold. Disconnect the pump from the representative
sampling medium and the calibrator.
14. Allow the pump to go to sleep.
15. Place a fresh sampling medium in line and sample when ready.

This type of calibration using a Defender calibrator provides flow correction
across the complete operating range of the Leland Legacy (5 to 15 L/min)
in approximately 4 minutes. The operation calibrates each flow rate to a
primary standard. It can also provide a record of calibration for maintenance
and quality purposes if DataTrac for Leland Legacy Soware is used. SKC
recommends that a full calibration be performed during pump maintenance
and aer non-factory repairs.
Do NOT place sampling media in line for full calibration. Ensure the
battery pack is completely charged before starting a full calibration.
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
1. Use 1/4-inch tubing to connect the Defender suction port to the Leland
Legacy pump inlet.
2. Follow Steps 1 and 3 through 9 of Single-point CalChek Calibration on
pages 13 and 14.
3. Verify that the baery icon on the pump display shows at least two bars.
If it does not, charge the baery before proceeding.
4. Press Son the pump keypad 7 times to place pump in full calibration
mode.
5. The Defender calibrator will begin to automatically
calibrate the pump. Initial flow measurements are
taken without flow from the pump and the pump
flow rate is adjusted automatically. The pump will
display FCAL, CS1, and a brief flow rate. The pump
will continue to display CS2, then a flow rate, CS3, then
a flow rate, etc. until calibration is completed at all flow
rates between 5 and 15 L/min.
Note: CalChek full calibration can be aborted by pressing [ST]. The pump
will go into Hold.

6. CCAL will display during Calibration Check mode and will count down
to 1. The pump will stop running.
7. When calibration is completed, the Leland Legacy will
go to Hold. If the calibration was successful, the pump
LCD will revert to displaying pump run time as 0.0.
If there was failure during the calibration process, an
error code of E4[x] will appear (see CalChek Error Chart
on page 17).
Note: To remove a CalChek error code from the LCD, press Ò.
8. Allow the pump to go to Sleep mode to write calibration data to pump
memory.
CalChek Full Calibration Data
Requires DataTrac for Leland Legacy Software
Full calibration completely clears pump history, run time parameters, and the
DataTrac Scheduler. Full calibration data can be viewed and printed by going to
the DataTrac Pump Manager window in DataTrac for Leland Legacy Soware
and clicking on the View menu. Choose Calibration Info. This will display
calibration results, pump serial number, and date of the last full calibration. A
buon allows this data to be printed. The printed report contains pump version,
date printed, and a validation code to perform data verification.
CalChek Full Calibration Data Verification
Requires DataTrac for Leland Legacy Software
To ensure that printed calibration data has not been tampered with, pull
down the Tools menu in the Calibration Info window and choose Confirm
Validation Code. Enter the data from the printed report, including the
validation code. DataTrac Soware will indicate whether the information is
completely valid or if a parameter has been changed.
When entering data to confirm the validation number, enter the
date in the following format: mmm, dd, yyyy (e.g., Aug 18 2009).
