Press ENT key (or CAL key) to confirm the reading. The pH Monitor re-calculates electrode properties based on the calibration. The new slope (in mV) is shown in the upper display and pH reading at 0mV (pH7. 00 ± offset) is shown in the lower display. Press ENT key to exit from the calibration. The pH Monitor reverts to pH measurement mode. · · To exit from pH calibration mode without confirming calibration, press and keys together. When confirming the buffer measurement, if measured pH value is not within ±1. 00pH from selected buffer value, the electrode annunciator blinks and ERR indicator appears in the display. This error can also occur if non-standard buffers are used or the electrode has worn out. If this happens, press both and keys together to restart the calibration beginning from Step1. · When calibrating with manual temperature compensation, the meter automatically changes from the preset `process temperature' to the `calibration temperature'. After leaving the calibration mode, the pH Monitor reverts back to `process temperature'. 4. 3. 2 For NIST Buffer Make sure that the pH Monitor is set to accept NIST standard buffer in the Setup mode. (Refer Section 5. 4 for Buffer Selection Settings) The factory default is USA standard. Press ENT key (or CAL key) to confirm the reading.

After leaving the calibration mode, the pH Monitor reverts back to process temperature. 4. 4 ORP Calibration The pH Monitor allows a single point ORP calibration. ORP calibration process is available only when the measurement mode is set to ORP.
