Chapter 6 — Calibration and System Protocols
To calibrate the Sensor, you must use the optional CheckPoint vial sampling Kit. Refer to the
Connecting the Vial Sampling Kit on page 74 for instructions on connecting the vial sampling kit. For
additional details on the various calibration procedures, see the application note called “Calibration of
the CheckPoint Portable/On-Line TOC Sensor,” available from our website.
NOTE: If you are using the CheckPoint with a battery previously provided by SUEZ, make sure the
battery has been fully charged in the external charger before starting calibration.
Flow Rate Calibration
The flow rate calibration should be performed whenever the pump head is replaced. This procedure
assumes CheckPoint is installed on a pressurized water system.
1. If the Sensor is taking measurements, press the button and F1.
2. Shut off the sample supply line. Disconnect the tubing from the Sensor’s Waste port. If your
Sensor has a Bypass port, connect the waste line to the Bypass port. (Remove any other
lengths of tubing and fittings from the waste line.)
3. Connect the short length of waste tubing from the accessories kit to the Waste port.
4. Place the other end of the tubing in the graduated cylinder from the accessories kit.
5. Press the button.
6. Press F1 to select the Mode screen.
7. Press F1 to select Calibration.
8. Press F3 to select Flow Rate Calibration.
9. Press F1 to fill the pump outlet tubing with water (20 seconds). Insert the end of the flow rate
calibration drain tubing into a dry 10 mL graduated cylinder. If the waste line has not filled in the
allotted time, press F4 to cancel. Repeat from Steps 8 - 9 until the fluid path has been filled.
10. Press F1 to start the pump. The pump will operate at twice normal speed for 5 minutes.
11. Record the volume of water collected in the cylinder at the end of this 5-minute period (there
should be close to 5 mL). Enter this volume as prompted by the Sensor. Press F1 to temporarily
apply new settings. The Sensor will calculate a new volume per revolution for the pump.
