6. Operation
ENGLISH
6.1. Measurement
Note: The instrument must be calibrated before taking the
first reading.
1. Press to turn on the instrument.
2. Remove the sensor protector.
3. Clean the sensor with deionized water.
4. Stir the sensor uniformly in the sample, holding it by the
top.
6.1.1. Stability measuring
Follow the diagram.
The reading is not locked on the screen until the sensor sig-
nal varies less than:
- pH: 0.01 pH for 6 sec.
- EC: ± 1 digit for 6 sec.
- Redox: 0.5 mV for 6 sec.
Once the reading has stabilized, the screen lights up for
2 sec.
6.1.2. Continuous measuring
Once stability measuring has begun, press the key
twice.
The instrument displays the measured value directly on
screen at all times.
The continuous reading should always be started after be-
ginning a stability reading (see diagram).
To end a continuous reading, press .
The display will light up for 2 sec.
Note: If the measuring instrument is not used for 5 minutes,
it will shut itself off automatically.

6.2. Units of measurement
The sensION™+MM150 automatically recognizes the sen-
sor connected and displays the relevant values and units on
screen:

6. Operation
6.3.2. One-point calibration
Stir gently holding the sensor by the handle. Do not hold it by the tube to avoid
heating of the buffer solution.
Follow the diagram on the next page.
One-point calibration is acceptable when pH values around that of the buffer
used are being measured.
One-point calibration only corrects the asymmetry potential of the electrode.
Notes: If the measuring instrument is not used for 5 minutes, it shuts off
automatically.
If an anomaly occurs during calibration, an error message will appear on
screen (see pg. 23).
Fig. 6. Preparation
6.3. pH calibration
Important note: Before turning on the instrument, check that the sensor is connected.
The instrument must be calibrated before taking the first pH reading.
The calibration can be performed with 1, 2 or 3 points.
6.3.1. Preparation
1. Fill the tubes with the buffer solutions (note the fill level).
2. Unscrew the protector containing the electrolyte and rinse the sensor with deionized water.
3. Screw the sensor on to the tube containing the first buffer.

6.3.3. Two- and three-point calibration
Follow the diagram below.
The equipment will repeat the process described for the first
buffer solution with the second and third.
Stir gently holding the sensor by the handle. Do not hold it by
the tube to avoid heating of the buffer solution.
Notes: if the measuring instrument is not used for 5 minutes, it
shuts off automatically.
If errors occur during calibration, an error message will appear
on screen (see pg. 23).
When you switch buffers, rinse the sensor with deionized water.
The buffer solutions in the calibration tubes can be used for
approximately four or five calibrations. It is recommended to
use fresh buffers.

6.4.2. One-point calibration
Dip the sensor into the tube several times to homogenize the liquid. Do not
hold it by the tube to avoid heating of the standard solution.
Follow the diagram on the next page.
This form of calibration is acceptable when conductivity values around that
of the standard solution used are being measured.
Note: if the measuring instrument is not used for 5 minutes, it shuts off
automatically.
If errors occur during calibration, an error message will appear on screen
(see pg. 23).

6.4. Conductivity calibration
Important note: before turning on the instrument, check that the sensor is connected.
The instrument must be calibrated before taking the first conductivity reading.
The calibration can be performed with 1, 2 or 3 points.
6.4.1. Preparation
1. Fill the tubes with the standard solutions (note the fill level).
2. Unscrew the protector and rinse the sensor with plenty of deionized water.
3. Screw the sensor on to the tube containing the first standard.

Important: before beginning calibration, rinse the
sensor with plenty of deionized water, followed by
the first conductivity standard.

6.5. Redox calibration (only with sensor 5048)
Important note: before turning on the instrument, check that the electrode is
connected.
Redox electrodes do not have a significant drift of the potential, which is why
they are not typically not calibrated. However, some deviations of potential
may occur after continued use of the electrode as a result of changes to the
metal surface or contamination of the reference electrode.
6.5.1. Preparation
1. Fill the tube with the 200 mV standard solution (note the fill level).
2. Unscrew the protector containing the electrolyte and rinse the electrode
with deionized water.
3. Screw the electrode on to the tube containing the standard.
6.5.2. Calibration
Stir gently holding the sensor by the handle. Do not hold it by the tube
to avoid heating of the standard solution.
Follow the diagram.
Note: if the measuring instrument is not used for 5 minutes, it shuts off
automatically.
If errors occur during calibration, an error message will appear on
screen (see pg. 23).
