Calibration
Calibration (High Flow: 1000 to 5000 ml/min)
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
1. Run pump for 5 minutes before performing calibration.
2. Connect pump inlet to the outlet of a primary standard calibrator with
representative sample medium in line.
With pump in a non-running state (no fl ashing blue LED):
3. Press  to enter user setup functions.
4. Press  until ADJ and FLOW fl ash on display. Press
 to increase fl ow. Press  to decrease fl ow. Dashed
lines will move up or down on the display to indicate
graphically the direction of the adjustment. Flow rate
will not display on pump LCD. Observe the calibrator
to determine fl ow rate.
5. Follow the calibrator operating instructions. Once the desired fl ow rate is
indicated on the calibrator (within ± 5%), press [] to accept fl ow setting and
to exit user setup functions. The pump will be ready to run.
• Changing the fl ow rate in user setup functions will not clear accumulated
run time.
• Changing the timed run and/or run delay settings in user setup functions will
automatically clear accumulated run time.
6. Disconnect the calibrator and tubing. Replace representative tubes with new
unexposed media for sampling.
