The tag will blink on the LCD until the reading is
stable.
When the reading is stable and close to the selected buffer,
READY tag will be displayed and CFM tag will blink.
Press
CFM
to confirm calibration.
The calibrated value will be displayed on the primary LCD
and the second expected buffer value on the secondary
LCD line.
Note:
The instrument will automatically skip the buffer used for the first point.
It also skips 6.86 if 7.01 buffer was used and viceversa. Likewise, it will
skip 9.18 if 10.01 buffer was used and viceversa.
After the first calibration point is confirmed, immerse the pH electrode and
the temperature probe approximately 4 cm (1½) into the second buffer
solution and stir gently. The temperature probe should be close to the pH
electrode.
If necessary, press the
ARROW
keys to select a different buffer value.
The tag will blink on the LCD until the reading is
stable.
When the reading is stable and close to the selected buffer,
READY tag will be displayed and CFM tag will blink.
