The following calibration standards are automatically recognized;
See Section 9.6 to change the buffer group
1) Press
as needed to select pH.
2) Dip the pH and ATC electrodes into pH buffer and press
. The
secondary display will lock on the appropriate buffer value. Provide
stirring for best results. When the
READY indicator appears, press
to accept. The primary reading will flash briefly before the
secondary display begins scrolling the remaining available buffers.
3) Rinse the pH and ATC electrodes then dip into the next pH buffer.
The secondary display will lock on the appropriate buffer value.
When the
READY indicator appears, press
to accept. The
primary reading will flash briefly then display the percent efficiency
(slope) before the secondary display begins scrolling the remaining
available buffers.
4) To calibrate another buffer repeat step 3) or press
to return to
the measurement mode.
Note: The meter will automatically return
to measurement mode upon successful completion of the number of
specified calibration points. To specify a different number of pH
calibration points see Section 9.6.
TIPS: A single point (offset) calibration is only allowed with pH 7.00 or
pH 6.86 buffers.
When the first calibration value is accepted during a new calibration,
all prior calibration values are erased.
Press
at any time to abort calibration and return to measurement
mode.
