Page 21: Basic Vs Standard Ph Mode
edge’s pH meter operation is con gured by using the SETUP key with a pH probe pH Meter connected to the meter. The parameter-speci c options will be seen inserted Con gurations into the menu. If Basic mode is “On”, the pH parameter list will not be displayed. See Basic mode for a description of this operation before choosing how to SETUP the meter. - Page 22 Preparation Pour small quantities of the bu er solutions into clean beakers. If possible, Calibration use plastic to minimize any EMC interferences. For accurate calibration and to minimize cross-contamination, use two beakers for each bu er solution; one for rinsing the electrode and one for calibration. If you are measuring in the acidic range, use pH 7.01 or 6.86 as the rst bu er and pH 4.01 (or 3.00*) as the second bu er.

Rinse and submerse the pH electrode approximately 3 cm (1¼”) into the second bu er solution and stir gently. If necessary, press the ARROW keys to select a Calibration di erent bu er value. The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the LCD until the reading is stable. - Page 24 Note: Custom bu er values can be adjusted ±1.00 pH around the set value during calibration. When a custom bu er is displayed, the “C1” or “C2” Calibration tag is displayed. First Calibration Point When performing a new calibration, or adding to an existing one, the user has a choice of how the rst new calibration point will be treated in reference to the existing calibration point.
- Page 25 Calibration If the instrument is not calibrated the calibration history has been deleted, or it has been calibrated only at one point, the electrode condition and the electrode response gauges will be empty. For a continuous display of the electrode’s condition and response, daily calibration is necessary.
