Using:
Select CALIBRATION in the Edit display.
Press the down arrow key to continue.
Using:
Select FIXED .
Using:
Select whether you would like to perform
a one, two or three-point calibration.
Using:
Select the first buffer to be used. The pH value
is given at 25˚C.
Choose from: IUPAC (pH 1.679, 4.005, 6.865,
7.000, 7.413, 9.180, 10.012 or 12.45),
Technical Series (pH 1.09, 4.65 or 9.23) or
4-7-10 Series.
This display (and "Buffer no. 3" display) appears
if a 2 or 3-point calibration has been selected.
The buffer options available are the same as
those listed above.
The stability criterion set in this display will
determine when the electrode signal is
accepted as being stable, e.g. when the "drift"
is less than 50 mpH/min, the result will be locked
on the display.
Note: If "0" is entered the measurement can be
accepted manually by pressing .
Range avaliable: 0 to 400 mpH/min.
