4.6. Other options for calibration

Automatic buffers recognition
Technical buffers
pH 2 .00, 4 .01, 7 .00, 9 .21 and 10 .90 at 25°C (77°F) .
Buffers DIN 19266
pH 1 .679, 4 .006, 6 .865, 7 .000, 9 .180, 10 .012 and 12 .454 .
User's buffers
Suitable when the two above mentioned options will not be
+
used . The sensION allows introducing the table pH/Temp .
™
PH31
for the desired buffers . See System, page 16 .
Calibration to X value
Manual re-adjustment of the measured pH at any value of the
scale . The pH readjustment is equivalent to calibration with only
one buffer .

Calibration data introduction
Manual introduction of calibration data for an electrode cali-
brated previously, for example in calibration laboratory .
Theoretical calibration
Selecting "theoretical calibration" the calibration data of the elec-
trode in use are replaced by the theoretical values at 25°C (77°F) .
This step is prior to the obtention of a calibration certificate .
Calibration frequency
Select between 0 h and 7 days . The instrument by default is
programmed for daily calibration and indicates the remaining
time to the new calibration .
Selecting 0 h the automatic re-calibration warning is deactivated .
Stability criteria.
Rapid criterion (variation < 0 .02 pH in 6 s) .
Standard criterion (variation < 0 .01 pH in 6 s) .
Strict criterion (variation < 0 .002 pH in 6 s) .
It is highly recommended to apply the same stability criteria to
measure and calibrate .
