Turning the ProSample On
Press the ON/OFF button once to turn the ProSample on. Press and
release the button again to turn the unit off.
Pump Calibration
The peristaltic pump must be calibrated at each sampling site, as the length and gradient of the suction hose impact
the calibration result.
NOTE: Calibration in a lab setting can be completed to verify the instrument is functioning properly, but it is still
highly recommended to recalibrate the instrument once at the sampling site.
Calibration Containers
The ProSample is calibrated to an upper and lower volume, resulting in a 2-point calibration. The upper calibration
will dispense a large volume of solution, typically over 1000 mL, whereas the lower calibration will dispense a small
volume, around 250 mL.
The volume dispensed during calibration will need to be accurately measured. It is recommended to obtain a large,
plastic graduated cylinder and a small, plastic graduated cylinder when measuring the amount of solution dispensed
during calibration.
Calibration Procedure
The following steps describe how to calibrate the ProSample peristaltic pump:
Calibration with large graduated cylinder
Instrument Setup and Calibration
1. Turn the ProSample OFF.
2. Remove the top of the ProSample housing and flip it over.
3. Remove the plastic 'elbow' piece from the end of the composite
sampling tube. There is a plastic bracket that keeps the
composite sampling tube in place during sampling – remove
the tube from this bracket.
4. Reinstall the top of the ProSample housing.
5. Pull the composite sampling tube out of the ProSample
housing. This will allow solution to be poured directly into a
graduated cylinder.
6. Place a graduated cylinder with a volume of at least 2000 mL
under the composite sampling tube.
7. Turn the ProSample ON.
8. From the Main Menu, navigate to Setup

the line and then dispense a large amount of solution into the
graduated cylinder three separate times.
