CM42-MAA301EAE00 Calibration and adjustment
Endress+Hauser 31
When you exit the measuring mode, the current measured value is displayed in the status bar in
the top left-hand corner:
7 Calibration and adjustment
The calibration provides important information on the condition of your sensor and the quality of
the pH measurement.
pH glass electrodes
In addition to the slope that has an ideal value of approx. -59 mV/pH at 25 C, the change in the zero
point also provides important information to the user. It is an indicator of the condition of the gel-like
layer of the pH glass and could point to a blockage in the reference system. Suitable maintenance would
involve cleaning or regenerating the sensor.
To perform a quick test, simply immerse the sensor in a buffer solution with the same pH value as the
internal buffer (e.g. pH 7). 0 mV would be an ideal value. The greater the deviation from the ideal value,
the poorer the condition of the sensor (20 mV is still acceptable in most situations).
7.1 DefinitionsCalibration (as per DIN 1319):
A calibration is defined as a set of operations that establish the relationship between the measured value
or expected value of the output variable and the related true or correct value of the measured variable
(input variable) for a measuring system under specified conditions.
A calibration does not alter the performance of the measuring device.
Adjustment
An adjustment corrects the value displayed by a measuring device, in other words the
measured/displayed value (the actual value) is corrected so that the reading agrees with the correct, set
value.

Calibration and adjustment CM42-MAA301EAE00
32 Endress+Hauser
The value determined during calibration is used to calculate the correct measured value and saved in
the sensor.
7.2 Zero point and slope
Using a mathematical function, the transmitter converts the input signal of the sensor y (raw measuredvalue) to the measured value x. In many cases, this function is a simple linear of the form y = a + b . x.
The linear element "a" is usually equivalent to the zero point and the factor "b" is the slope of the line.
The Nernst equation, which is used to calculate the pH value, is a typical linear relationship:
pH = -lg(aH+), aH+ ... activity of the hydrogen ions
Ui ... raw measured value in mV
U0 ... zero point (=voltage at pH 7)
R ... relative gas constant (8.3143 J/molK)
T ... temperature [K]F ... Faraday constant (26.803 Ah)
The slope of the Nernst equation (-2.303RT/F) is known as the Nernst factor and has the value
-59.16 mV/pH at 25 C.
7.3 Notes on the calibration
The following rules apply for all parameters:
Calibrate in a way that reflects conditions in the process.
If the process medium is constantly moving, also move the calibration solution accordingly (e.g.
use a magnetic stirrer if calibrating in the laboratory).

CM42-MAA301EAE00 Calibration and adjustment
Endress+Hauser 33
If your medium is relatively stationary, calibrate in solutions that are also stationary.
Make sure that the samples are homogeneous for reference measurements, sample calibration etc.
Use the same menu settings as those in the process to perform the calibration.
Example: If you automatically compensate for the temperature effect during pH measurement, switch
on automatic temperature compensation for the calibration also.
It is advisable to perform the laboratory calibration using the "Memobase" database software (-->
"Accessories"). This improves the availability of your measuring points and all the calibration and
sensor data records are stored securely in the database.
7.4 Calibration intervals
The service life of a pH glass electrode is limited. This is due, in part, to the deterioration and aging of
the pH-sensitive membrane glass. This aging causes the gel-like layer to change and become thicker
over time.
Symptoms of aging include:
Higher membrane resistance
Slow response
Decrease in the slope
A change in the reference system (e.g. due to contamination, i.e. unwanted redox reactions at the
reference electrode) or electrolyte solution dissolving away in the reference half cell can change the
reference potential, which, in turn, causes a zero point shift in the measuring electrode.
To ensure a high level of accuracy, it is important to readjust the pH sensors at set intervals.
The calibration interval depends heavily on the area of application of the sensor, as well as the requiredlevel of accuracy and reproducibility. The calibration interval can vary between daily and once every
few months.
Defining the calibration interval for the process
1. Check the sensor with a buffer solution, e.g. pH 7.
Proceed as specified in Step 2 only if the value deviates from the set point. No
calibration/adjustment is necessary if the value is within the defined deviation tolerance range
(see the Technical Information for the sensor).
2. Calibrate and adjust the sensor.
3. After 24 hours, check again with the buffer solution.a. If the deviation is within the permitted tolerance range, increase the checking interval by
doubling it for example.
b. If the deviation is larger, you must shorten the interval.
4. Continue to proceed as defined in Steps 2 and 3 until you have identified the suitable interval.

7.5 Types of calibration
7.5.1 pH measurement
The following types of calibration are possible:
Two-point calibration
With calibration buffers
Single-point calibration
Entry of a reference value
Sample calibration with laboratory comparative value
Temperature adjustment by entering a reference value
If using a combined sensor (CPS16D/CPS76D/CPS96D) you must calibrate both the pH electrode
and the ORP electrode to get reliable rH values, for example.
7.5.2 Measuring the ORP
The following types of calibration are possible:
Two-point calibration with medium samples (only ORP %)
Single-point calibration with calibration buffer (only ORP mV)
Data entry of an offset (only ORP mV)
Temperature adjustment via reference value
7.6 Two-point calibration
7.6.1 General information
Two-point calibration is the preferred method for pH sensors, particularly in the following
applications:
Municipal and industrial wastewater
Natural waters and drinking water
Boiler feedwater and condensates
Beverages
Calibrating with buffers with pH 7.0 and 4.0 is recommended for most applications.
Alkaline buffer solutions have the disadvantage that carbon dioxide from the air can alter the pH value
of the buffer on the long term. If calibrating with alkaline buffers it is best to do so in closed systems,such as flow assemblies or retractable assemblies with a rinse chamber, to minimize the effect of air.
7.6.2 With calibration buffers
pH measurement
You use calibration buffers to perform two-point calibration. The quality buffers supplied by
Endress+Hauser are certified and measured in an accredited laboratory. The accreditation (DAR
registration number "DKD-K-52701") confirms that the actual values and the maximum deviations are
correct and traceable.

35/44
CM42-MAA301EAE00 Calibration and adjustment
Endress+Hauser 35
To calibrate the sensor, remove it from the medium and calibrate it in the laboratory. Since Memosens
sensors save the data, you can always work with "precalibrated" sensors and do not have to stop
monitoring the process to perform a calibration.
Only use calibration buffers once.
Measurement of the ORP in % (2-point cal.)
To obtain useful ORP % values, you must adapt the sensor to your process. This is achieved through
two-point calibration. The two calibration points are characteristic of the most important states your
medium can assume in the process.
You require two different compositions of your medium that represent the characteristic limits of your
process (e.g. 20% and 80% value).
The absolute value in mV is not relevant for the ORP % measurement.
Measuring the ORP in % (data entry)
As an alternative to two-point calibration with medium samples, you can also define the two calibration
points via data entry. To do so, use data pairs in mV and % for the two calibration points that represent
the most important states of your process medium. Ideally, you will have determined the mV values
with a reference measurement.
7.6.3 Entering data for the zero point, slope and temperature (only pH)
You enter the slope, zero point and temperature manually. The function for determining the pH value
is calculated from these values. Thus, the data entry returns the same result as two-point calibration.
You must determine the slope, zero point and temperature alternatively.
7.7 Single-point calibration
7.7.1 Numeric input of a reference value (1-point cal.)
pH measurement
Single-point calibration is particularly useful if the deviation of the pH value from a reference value,
and not the absolute pH value itself, is of interest to the user. Applications for single-point calibration
include:
Process control
Quality assurance
Fluctuations in the process value should not exceed 0.5 pH and the process temperature must remain
relatively constant. As the measuring range is limited as a result, it is possible to set the slope to -59
mV/pH (at 25 C).
Alternatively, you can also use the "sample calibration". Here, you take a sample from the process and
determine the pH value in the laboratory. In the case of the laboratory sample, you must make sure that
the pH value is determined at the process temperature.

Measuring the ORP in mV
You enter the offset directly with this type of calibration. Use the measured value of a reference
measurement, for example, to determine the offset.
7.7.2 Sample calibration (grab sample cal., only pH)
With this type of calibration, you take a sample of the medium and determine its pH value (at process
temperature) in the laboratory. You then use this laboratory value to adjust the sensor. This does not
change the slope of the calibration function.
7.7.3 With ORP buffers (only measurement of the ORP)
With this type of calibration, you work with calibration buffers, e.g. ORP buffers from Endress+Hauser.
For this purpose, you remove the sensor from the medium and calibrate it in the laboratory. Since
Memosens sensors save the data, you can always work with "precalibrated" sensors and do not have to
stop monitoring the process for extended periods to perform a calibration.Only use calibration buffers once.
7.8 Temperature adjustment
The temperature sensor has to be calibrated at regular intervals to ensure the measured value is not
falsified by incorrect temperature measurement.
1. Determine the temperature with a reference measurement and, depending on the result, decide
whether you want to adjust the temperature sensor.
2. If you do, go to the "CAL/Temp. adjustment" menu.The current offset is displayed.
3. Start the adjustment and enter the new offset which you determined beforehand with the
reference measurement.
You can cancel the calibration any time by pressing the "ESC" key. No new data are then used to adjust
the sensor.
7.9 Calibrate
1. Press the soft key for "CAL".
2. Select the type of calibration.
3. Enter the necessary parameters.
(The parameters that have to be configured depend on the type of calibration selected.)
4. Start the calibration.
5. Follow the instructions in the menu.
6. Decide whether to use the calibration data captured, or to abort or repeat the calibration.
After calibration, the transmitter automatically switches back to the measuring mode and your
measuring point is now ready for operation.
If calibration is aborted using ESC, or if the calibration is faulty, the system continues to use theoriginal calibration data.
