Remove the electrode from the first standard, wash it well and then immerse it in the 20% standard. When the display stabilizes press the ENT key. The "CAL" indicator flashes and the controller adjusts its display to the 20% relative value and exits to the Measurement mode. Note: If there is a calibration error, the transmitter displays "ERR". In this case press the and keys simultaneously (escape) to restart the calibration, beginning from step 1. Note: If you stop calibration after entering the first value, or if calibration is defective, the controller will use its original calibration data. 5. 5 View actual zero and slope MEAS PH O C atc CAL ENT CAL ENT PH 1. While in Measurement mode press the CAL key. The display will prompt you to enter a security code. Leave the security code at "000" (view only mode). The display shows the slope in mV (upper value) and the pH reading at 0 mV (zero point, lower value). Note: If no key is pressed for 30 seconds the transmitter automatically returns to the Measurement mode. 3.

The controller returns to the Measurement mode. 6. 2 Electrode Offset (OFS) sub-function The electrode offset sub-function is only available if the controller is configured for pH measuring. Use this sub-function to set an offset that corrects the readings without removing the electrode from the control system. The controller will add or subtract the offset value from the measured pH and display the corrected value. However, if you need to offset the value beyond the average offset you would expect in your application type, consider a full calibration or even electrode replacement. Record the controller's pH reading at the time you take the sample. [. . . ] Thermo Scientific will not be responsible for damage resulting from careless or insufficient packing. A restocking charge will be made on all unauthorized returns.
