pH CALIBRA
TION
If the current confirmed buffer has no correspondence in the existing stored calibration and this is
not full, the current buffer is added to the existing stored calibration.
If the existing stored calibration is full (five calibration points), after confirming the calibration point,
the instrument will ask which buffer will be replaced by current buffer.
Press / keys to select another buffer to be replaced.
Press
CFM
to confirm the buffer that will be replaced.
Press
CAL
or
ESC
to leave replace mode. In this case, the buffer will not be memorized.
Note: The replaced buffer is not removed from calibration list and it can be selected for the
next calibration points.
WORKING WITH CUSTOM BUFFERS
If at least one custom buffer was set in
SETUP
menu, it can be selected for calibration by pressing
the / keys. The
Custom
functional key will be displayed.
Press
Custom
if you want to adjust the buffer value according with current temperature.
Use the / keys to change the buffer value.
Press
Accept
to accept new value or
ESC
to exit changing mode.
Note: Custom buffer value can be adjusted in a ±1.00 pH window, around the set value.
