CALIBRATION AND SAMPLING
Calibration
Calibrate pump fl ow rate with the sampling head loaded with a cartridge in
line. See pump and calibrator operating instructions.
Wear disposable, clean, lint-free nylon or powder-free surgical gloves to
handle the sorbent and cartridge.
Ensure pump has run for 5 minutes
before calibrating. Ensure rain
cover is removed from inlet and
that sampling head is completely
assembled with a fully loaded
cartridge (see Inserting a Cartridge
into the Sampling Head).
Thread calibration adapter into
sampling head inlet.
Set and calibrate pump fl ow rate to 10 L/min (see Leland
Legacy Quick Guide on page 9). Record the pre-sample fl ow
rate. See pump and calibrator operating instructions.

When calibration is completed,
disconnect calibrator and tubing
from calibration adapter. Remove
calibration adapter from sampling
head.
Use provided short length of calibration tubing to connect inlet of calibration
adapter to outlet of a calibrator to form a calibration train.
Unscrew quick-connect plug on side of case. Use tubing with quick-connect
fi  ing to a ach case (pump) inlet to exhaust of sampling head.
Ensure O-ring is installed on the quick-connect fi  ing before inserting it
into the inlet. Absence of the O-ring can aff ect measurements. See page 14
for Replacement Parts.
