Appendix B

Sensor Enabled

When the sensor is enabled, and volume calibration is selected, a single manual calibration is taken. It does not matter if multiple volumes are programmed (such as when using stormwater or upset sampling). When the sensor is enabled, a single “Manual Calibration” choice provides sufficient information to adjust the sensor to all programmed volumes (see Table 24).

Calibration Procedure—Sensor Disabled:

1.From the Main Menu, press OPTIONS.

2.Press VOLUME CALIBRATION.

3.Select the desired volume to calibrate if more than one is listed (see Table 24).

4.Slip the pump tube off the sample fitting (near where it exits the pump housing) and direct the end of the pump tube into a graduated cylinder.

5.Press START PUMPING. The pump will purge the line, and start pumping a sample.

6.Press any key when the desired sample volume has been reached in the graduated cylinder. The pump will stop to allow the line to completely drain and then reverse to post-purge the line.

7.If the pumped sample volume is correct, press DONE. If not, repeat the calibration cycle by pressing TRY AGAIN.

8.When finished, re-install the pump tube onto the sample fitting.

Note: To check the sample size after calibration use the Manual Mode function key to take a grab sample. Do not go back into calibration to check the volume since the volume compensation is reset to zero at the start of a calibration.

If one or more Timed Rinses are selected (sensor disabled), then they must be calibrated as well. The Timed Rinse will rinse the intake line up to 3 times prior to taking a sample.
