After the first calibration point has been confirmed, the calibrated
value is displayed on the first LCD line and the second expected
buffer value on the third LCD line (i.e. pH 4.01). The first buffer value
is saved and the second proposed buffer is displayed blinking.

4. Press CAL/EDIT to exit 1‑point calibration and return to
Measurement mode.
Up to 5-point Calibration
To continue calibrating, rinse and place the probe tip approximately
4 cm (1 ½”) into the second buffer solution and stir gently.
If needed, use the
keys to select a different buffer value.
Note: When attempting to calibrate with a different buffer (not
yet used), the previously used buffers are displayed blinking.
Follow 1‑point calibration steps for up to 5‑point calibration.
Press CAL/EDIT to store the value and return to Measurement
mode.
For improved accuracy, a minimum of 2‑point calibration is
recommended.
Note: When performing a new calibration (or adding to an
existing calibration), the first calibration point is treated as an
offset.
Press CAL/EDIT after the first or second calibration point
has been confirmed, and the instrument stores the calibration
data and returns to Measurement mode.
