The calibration default settings enable the calibration routines to be accessed in
the particular calibration menu.
Calibration routines that are not enabled are not visible in the calibration menu.
Additional calibration default settings are explained in the following table.

Possible settings
Buffer set 1 to 3
factory set:
• Buffer set 1:
Reference Buffer solutions for
calibrating pH measuring in-
struments acc. to DIN 19266
• Buffer set 2:
Technical Buffer solutions,
preferably for calibrating and
adjusting technical pH mea-
suring instruments acc. to DIN
19267
-2 to 16 pH

Explanation
Buffer set tables contain pH-values for
selected buffers solutions as a function
of temperature. These tables can be
prepared/edited on the basis of com-
mercially available standard solutions
(DIN 19266, NIST, misc. technical Buf-
fer solutions etc.) or customer-specific
information. With the aid of such
tables, Buffer solutions can be recog-
nized automatically during calibration.
The pH-value data for the Buffer solu-
tions used must be contained in the se-
lected Buffer set table.
When a Buffer set is selected, this acti-
vates automatic buffer recognition and
the entry fields for the settings "pH buf-
fer 1 to 3" are hidden.
You need the JUMO PC setup program
to edit Buffer set tables.
manual entry of the pH-values of the
Buffer solutions being used for the cali-
bration
Depending on the selected Calibration
routine, the corresponding entry fields
for "pH buffer 1 to 3" are displayed.
The pH-values of the Buffer solutions
used must be at least 2 pH apart.
