Calibrating ORP probe

[pperez]

Can i calibrate the probe with the 400mv from pinpoint? If so, how? I can't find my booklet.

Thanks.

From the website;

ORP Calibration
It is not necessary to calibrate the ORP probe of the AquaController III. It has been properly calibrated at the
factory to maintain accurate ORP readings for the lifetime of the controller. However, it is possible to calibrate
the probe if so desired. Quinhydrone, pH 4.00 and pH 7.00 calibration solutions are required for the calibration.
The following procedure should be used to calibrate the ORP:
1. Create a saturated solution of Quinhydrone and pH 7.00 calibration solution.
2. Select Setup:ORP Setup:ORP Calibrate from the AquaController III’s menus.
3. Place the ORP probe into the Quin-7.00 solution. Wait for the numbers on the bottom of the
LCD screen to stop changing. It does not matter what value is displayed only that it is not
changing. When the display stops changing press the select button.
4. Create a saturated solution of Quinhydrone and pH 4.00 calibration solution.
5. Place the ORP probe into the Quin-4.00 solution. Wait for the numbers on the bottom of the
LCD screen to stop changing. It does not matter what value is displayed only that it is not
changing. When the display stops changing press the select button.
6. The ORP probe is now calibrated.

Thanks. I guess i'll have to get the other kit since this is just a 400mv solution from pinpoint. I have to get this one then.
