4. Operation
4.6. Other options for calibration
Automatic buffers recognition
Technical buffers
pH 2.00, 4.01, 7.00, 9.21 and 10.00 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
™
+
PH 31
allows introducing the
table pH/Temp. 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.
Important note:
Once the calibration is
re-programmed, it will be
performed with the new
programming.

ENGLISH
Start of calibration
with automatic
recognition of the
selected buffers.
Start calibration
The instrument goes
to MEASURE menu.
The theoretical cali-
bration will be used.
The instrument goes to the
option “CALIBRATE pH” and
it must be recalibrated.
The instrument goes to
MEASURE menu. The
introduced calibration
data will be used.
