4.7.2 Entering IDs/PIN

The three softkeys and READ key are used for navigating on the keypad and entering the ID/PIN.
Example: WATER
1 If A is highlighted, press
V is highlighted.
2 Press once.
W is highlighted.
3 Press READ to enter W.
4 Repositioning the highlighted bar to A, T, E and R, and press READ to enter each letter of sample ID in
sequence as described in steps a - c.
5 Reposition the highlighted bar to OK, and press READ to save the sample ID.

4.7.3 Editing values in a table

The meter has a feature, which allows the user to enter, edit or remove values in tables. (for example,
temperature and buffer values for a customized buffer group). This is accomplished by using the softkeys on
the display to navigate from cell to cell.
1 Press READ to start editing the cell in the table.
The softkeys on the display change.

4.8 Calibration

The SevenGo Duo pro™ pH/DO meter allows you to perform pH and ion calibrations for up to 5 points and DO
calibrations for up to 2 points.

4.8.1 Running a one-point pH/ion calibration

1 Press and hold MODE for 3 seconds to switch to single channel pH or ion measurement screen when in
dual channel measurement.
2 Place the electrode in a calibration buffer and press CAL.
Cal 1 appears on the display.
3 The meter endpoints according to the preselected endpoint mode after the signal has stabilized or after
pressing READ.
The relevant buffer value is shown on the display.
4 Press End to accept the calibration and return to sample measurement.
The calibration result (offset and slope for pH) is shown on the display.
— or —
5 Press Save to keep the calibration.
6 Press EXIT to reject the calibration.
Note
With the one-point calibration only the offset is adjusted. If the sensor was previously calibrated with a
multipoint calibration the previously stored slope will remain. Otherwise, the theoretical slope (-59.16 mV/
pH) will be used.
