It is recommended that you perform 2-point calibration at room temperature (25 oC), starting with the first buffer at pH 6. 86 followed by any other buffer value.

Immerse the temperature probe in the buffer solution if ATC mode is enabled. Immerse the potential matching pin in the buffer if symmetrical mode is enabled. Lower display shows pH 6. 86 (NIST standard buffer). Upper display shows the current uncalibrated pH reading. LCD shows `READY' annunciator when the reading is stable. 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. 3 4 2-Point Calibration: 1 CAL 2 CAL CAL pH 3 CAL pH 4 mV 5 MEAS ENT READY ENT READY ENT ENT READY PH pH pH CAL pH °C ATC 3 CAL READY pH ENT pH CAL 3 CAL READY pH ENT pH CAL 3 CAL READY pH ENT pH CAL - 20 - 1 2 From pH measurement mode press CAL key to enter calibration mode as described in section 4. 2.

Immerse the potential matching pin in the buffer if symmetrical mode is enabled. Lower display shows pH 6. 86 (NIST standard buffer). Upper display shows the current uncalibrated pH reading. LCD shows `READY' annunciator when the reading is stable. The pH Monitor moves to the second calibration point. The lower display shows next standard buffer value (pH 4. 01). Use and keys to select your second buffer from one of the preset values: pH 4. 01 or 1. 68 or 9. 18 or 12. 45. Remove the electrode from the first buffer, wash and then immerse it into the second buffer.
