CAL CON 1P
Explanation
For this you can use any one buffer solution
if its pH value at the current temperature is
known. The calibration will be the more
exact the nearer the pH value of the buffer
solution is to that of the test sample.
Follow the instructions on the display. As
soon as the measured value is stable, the
-
next display indication appears.
