— 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
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.

: 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.
