When using the analyzer to measure ORP, this function
is not provided.
(The ORP display format is fixed to show
mV values as only whole numbers.) For pH measurement,
choose the MEASURE screen display format to be XX.XX
or XX.X. This format setting has no effect on edit/selection
screens, which always show pH values in a XX.XX format.

When using the analyzer to measure ORP, this function
is not provided.
For pH, configure the analyzer to use one
of these buffer sets for pH calibration:
•
4.00, 7.00, and 10.00
•
DIN 19267 standard (1.09, 4.65, 6.79, 9.23, and 12.75)
NOTE:
When using buffers that are not included in either of
the analyzer buffer sets, disregard selecting the
buffer set. In this case, use only the “1 (or) 2 POINT
SAMPLE” method for calibration.
The analyzer automatically recognizes pH values from the
selected buffer set and uses its associated built-in table of
pH-versus-temperature values to improve measurement ac-
curacy. To select a buffer set:
