Note: to get accurate readings, use pH 4.01
if you are going to measure acid
samples or pH 10.01 for alkaline mea-
surements.
Shake briefly and wait one minute before
adjusting the slope trimmer to display pH 4.01
(or 10.01) on the LCD if the temperature of
the buffer solution is at 25°C, if not refer to
the chart on page 43 for appropriate buffer
value for the corresponding temperature.
The calibration is now complete and the in-
strument is ready for use.
Note: If the meter is used in conjunction with
a PT 100 temperature sensor, immerse
it into the buffers during the calibration
procedure.
