Attach the PTFE tubing to the pump inlet port and push your sorbent tube for
calibration into the relevant adapter. The sampling arrow on the TD tube
should be pointing towards the pump.
NOTES
Use the back-pressure adapter when setting flows of up to 100 mL/min;
use the plastic tube adapter when setting flows in excess of
100 mL/min.

Connect the sampling end of the TD tube to a suitable flow measuring device,
e.g.
digital flowmeter. (C-FLMTR)
NOTES
Markes digital flowmeter (C-FLMTR) is limited to flows of 500 mL/min
[8]
Ensure the flow measuring device is on and working.
[9]
Select 'Calibrate' from the start menu.
The display will indicate the set flow rate and the pump will begin to run in
calibration mode.
[10]
Use the adjustment keys to adjust the flow rate on the display screen until it
matches that of the flow rate measured by the calibration device, press
<ENTER>. Using the information of the actual flow rate, the pump will adjust to
run at the calibration point.
[11]
When the desired flow rate has been reached, press <ENTER> to set
calibration. The pump is now ready for sampling.
[12]
To power the pump off, press and hold the power key until the power down
window appears and the countdown is complete.
