OPERATION
Setting/Calibrating Flow Rate from 1 to 5 L/min
•
Allow pump to equilibrate after moving it from one temperature extreme to another.
•
Charge pump battery completely before calibration and sampling.
•
To achieve the best results, run the pump for 10 to 15 minutes before calibration.
1. Turn on the pump using the on/off button. If elapsed time from the last sampling run is still displayed, touch
and hold the PUMP key on the screen touch keypad to return to the set/calibrate flow screen.
2. Prepare the calibrator. See calibrator instructions.
3. Set up a calibration train (
Figure 3
).
4. Using the up and down arrow keys on the pump set/calibrate flow screen, adjust flow until the calibrator
indicates the method-specified flow rate.
5. Touch the PUMP key to pause/stop the pump. The pump is now set to the selected flow rate.
6. Disconnect the pump from the representative sampling medium and calibrator. Proceed to Sampling.
