2.The meter is capable of calibrating up to 5 points using USA
or NIST pH buffer standard. There are 1.68-4-7-10-12.45 five
points for selection.
3.It is recommended that you start with first buffer at 7.00 pH .
The meter may select pH buffer value by pressing or
to calibrate with correct calibration value. +/-0.5 of the selected
range.
