Multiple-point (Full) Calibration Using CalChek
This type of calibration using a Defender calibrator provides fl ow correction
across the complete operating range of the Leland Legacy (5 to 15 L/min)
in approximately 4 minutes. The operation calibrates each fl ow rate to a
primary standard. It can also provide a record of calibration for maintenance
and quality purposes if DataTrac for Leland Legacy Soft ware is used. SKC
recommends that a full calibration be performed during pump maintenance
and aft 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 12 and 13.
3. Verify that the batt ery icon on the pump display shows at least two bars.
If it does not, charge the batt ery before proceeding.
4. Press
 on the pump keypad 7 times to place pump in full calibration
mode.
5. The Defender calibrator will begin to automatically
calibrate the pump. Initial fl ow measurements are
taken without fl ow from the pump and the pump
fl ow rate is adjusted automatically. The pump will
display FCAL, CS1, and a brief fl ow rate. The pump
will continue to display CS2, then a fl ow rate, CS3, then
a fl ow rate, etc. until calibration is completed at all fl ow
rates between 5 and 15 L/min.
Note: CalChek full calibration can be aborted by pressing []. The pump
will go into Hold.
