- Page 11 ONE-POINT CALIBRATION ELECTRODE CONDITIONING & MAINTENANCE For optimum accuracy it is always recommended to perform a two- point calibration, but for a faster operation it is also possible to carry out a single-point procedure. Buffers at pH 7.01 or pH 6.86 (NIST) are normally the most appropriate for this purpose, even though the meter can be calibrated with any of the memorized calibration values.
- Page 12 Notes: TEMPERATURE CORRELATION • When the meter is not calibrated or calibration is cleared (default FOR pH SENSITIVE GLASS values loaded) there is no “expired calibration”, and the display always shows a blinking CAL tag. The resistance of glass electrodes partially depends on the temperature. •...
