If two-point calibration was selected, the lower section of the display will now show its next lower "pH" buffer. Use and keys to select the second buffer from one of these preset values: - pH 1. 68, pH 4. 01, pH 9. 00, pH 9. 18 and pH 10. 01. Remove the electrode from the first buffer, wash and then immerse it into the second buffer. After calibrating with the second buffer value, the controller will automatically display the slope in the upper and the zero point in the lower section of the display. Note: You can also view the values for zero point and slope without calibration (see section 5. 1. 2 for instruction). The zero point and slope are redetermined after each calibration. 7. Note: If you entered the Calibration mode from the Setup mode, the controller will return to the setup menu. 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: When calibrating with manual temperature compensation, the controller automatically changes from the preset process temperature to the calibration temperature. After leaving the Calibration mode, the controller switches back to the process temperature (for setting the calibration temperature and the process temperature, see section 6. 3). 5. 3 ORP­mV Calibration If controller is configured for ORP-mV measuring you can perform only a one-point calibration. SETUP HOLD HOLD CAL MV CAL HOLD MV meas 250 CAL 250 1. Note: If the display reads "CAL PH", see section 6. 9 for procedures on how to switch from pH to ORP-mV readings. The display shows the current mV output of the electrode without any offset adjustment. The controller calculates the correction factor and returns to the Measurement mode. 5. 4 ORP -% Calibration If controller is configured for ORP-% measuring you can perform a calibration at two points using a low concentration sample (20%) and a high concentration sample (80%). To calibrate the controller for ORP %: SETUP HOLD HOLD CAL HOLD CAL meas % 59. 0 CAL CAL 1. Note: If the display reads "CAL PH", see section 6. 9 for procedures on how to switch from pH to ORP-% readings. The display prompts you to place the sensor in the high concentration sample (relative value of 80%). Place sensor in the high concentration sample, then press the ENT key. The unit automatically adjusts its reading to match the solution value. The display prompts you to place the sensor in the low concentration sample (relative value of 20%). Remove the electrode from the first standard, wash it well and then immerse it in the 20% standard. [. . . ] If repair or adjustment is necessary and has not been the result of abuse or misuse within the designated period, please return ­ freight pre-paid ­ and correction will be made without charge. Thermo Scientific/ Eutech will determine if the product problem is due to deviations or customer misuse.
