2.2 Hardware description

The instrument hardware is made of one main board, up to 3 measurement boards - one for each measurement channel (= one per sensor), a power supply and a battery pack as options.

The main board includes the controls for power, display, the touch screen, the barometric sensor, the alarms, and communication ports. The measurement board(s) performs measurements and executes commands from the main board. It holds the "Analog outputs" and "Relays" that send information to external systems, and "Digital Inputs" that receive information from external systems such as a “Hold” input.

A hardware watchdog is activated at program start up, to check that the system is not frozen (i.e. infinite loop, system crash, etc.). If the watchdog is not refreshed by the software every minute, the measurement display, the relays and the analog outputs are frozen for up to 2 minutes. Then the reset shuts down the instrument for 10 seconds and the start-up procedure is performed. At the same time all the hardware (sensor, measurement board) are reset.

2.3 Model identification system

The analyzer identification number and the instrument serial number are located on the label on the back panel, and can be found on order confirmation and invoice papers.

The different models available are described in the following two matrices. Depending on the channel configuration, the first three digits of the model number will be either 510, 511 or 512 as illustrated below.

3.6 Connectors assembly instructions

Potential Electrocution Hazard. In order to maintain the NEMA/IP environmental ratings of the enclosure, use only conduit fittings and cable glands rated for at least NEMA 4X/IP65 to route cables into the instrument.

3.6.1 Cable gland wiring instructions

A waterproof cable gland is provided each time a cable must be connected inside the instrument. The nickel-plated brass cable glands are EMC-types, designed so that the cable shields attach directly to the instrument housing as a ground. Typical cable wiring instructions are detailed below.

WARNING

Gland parts (washers not shown):

1. Nut

2. Rubber gasket (seal)

3. Gland fitting with O-ring (attached to

instrument housing)

1. Unscrew the cable gland nut. Inside, the assembly is composed of a rubber gasket, and two metal washers. Note that the ethernet gland on panel and wall mount instruments does not have washers and the gasket is cut.

2. If wiring a sensor cable, the cable has already been prepared so simply remove the piece of plastic protection from the exposed shielding.

For other cables, strip off external insulation as required, and 25 mm of shielding. Strip the wires about 8 mm from their ends (see illustration below).

3. Pass the cable through the nut, the rubber gasket, and the two washers

4. Pinch the shield so that its entire circumference is pressed between the two washers and

pass the cable into the housing, blocking the cable gland

NOTICE

It is vitally important to ensure the shielding is pinched and secured between the two washers to ensure the shielding attaches directly to the instrument housing as a ground. Failure to do this could cause damage to the instrument, and for sensor cables give incorrect readings.

5. Reattach and tighten the cable gland nut

6. Attach the wires to the corresponding terminal block connections

Page 35

3.6.2 Ethernet connector (table version)

The Harting RJ Industrial® IP 67 Push Pull connector can be locked and unlocked using one hand and minimal force. Only a few steps are necessary in order to quickly and reliably attach an Industrial Ethernet cable to the Harting RJ Industrial® connector. Only a Harting cable should be used.

3.8 Connections to electronic boards

Potential Instrument Damage. Delicate internal electronic components can be damaged by static electricity, resulting in degraded performance or eventual failure.

Note: Any loose connection wires should be bundled tightly together with the use of nylon cable ties.

3.8.1 Sensor cable

An ORBISPHERE cable is needed to connect the sensor(s) to the instrument. The table instruments have a Lemo 10 connector where a sensor cable has to be connected. The other versions have a cable gland for cable passage, and the cable must be permanently connected to the corresponding measuring board connector.

Therefore the table instruments require a standard sensor cable, while the other versions require a sensor cable with free wires on the instrument end. The free wires are connected to the connector J8 on the corresponding measuring board, as detailed later in this chapter.

Note: The numbers and earth symbol are stamped on the end of the connector. Ensure it is connected correctly.

NOTICE

Installation

3.10 Sensor installation

3.10.1 EC Sensors

For EC sensor installation, servicing, and maintenance ensure you follow the instructions in the Sensor Installation and Maintenance manual that was supplied with the instrument.

3.10.2 TC Sensors

For TC sensor installation, servicing and maintenance ensure you follow the instructions in the TC Sensor Installation and Maintenance manual that was supplied with the instrument. Pay particular attention to the installation and connection of the purge gas supply.

Do not place the TC sensor into a liquid sample until a constant supply of dry purge gas has been connected, as liquid could condense inside the measuring chamber and cause damage to the thermal conductor chip.

To ensure the continuation of purge gas while the sensor is in contact with the sample, it is highly recommended to use a backup purge gas cylinder with an automatic changeover valve that activates when the first cylinder is empty.

NOTICE

The use of an ORBISPHERE Model 29089 gas regulator (or similar) is also recommended to deliver a constant, pressure regulated supply of dry purge gas to the sensor, filtered to 40 µm.

In addition, and to prevent any damage to the sensor electronics, the use of a purge safety backup unit (ORBISPHERE Model 32605) is highly recommended to ensure the supply of purge gas remains uninterrupted to the sensor in the event of a mains power outage.

The above ORBISPHERE accessories are explained in more detail in the TC Sensor Installation and Maintenance manual.

5.1 Selection of the view style

Numeric view

This is the default view. Display shows the numeric measurement value identified for each gas measurement channel available, a graphic showing measurement value evolution during the set time frame, and sample temperature.

This display can be configured to suit individual conditions and convenience.

Diagnostic view

The diagnostic view contains useful information for troubleshooting purposes. The amount of information displayed depends on the gas being measured and the channel configuration.

Statistic view

This feature offers statistical data that matches with Total Quality management tools. Statistics is a tool to better analyze how a process behave. The 51x statistics window gives some useful information.

The statistics are calculated from the data in the measurement file. The values are updated each time a new value is added to this file. Therefore the changes made in the configuration window are considered only once a new value is added.

Cp process capability

Cp is an index used to assess the width of the process spread in comparison to the width of the specification. It is calculated by dividing the allowable spread by the actual spread.

• A Cp of one indicates that the width of the process and the width of the specification are the

same.

• A Cp of less than one indicates that the process spread is greater than the specification. This

means that some of the data lies outside the specification.

• A Cp of greater than one indicates that the process spread is less than the width of the

specification. Potentially this means that the process can fit inside the specification limits

CPk process variability

Cpk takes into account the center of the data relative to the specifications, as well as the variation in the process.

• A Cpk value of one indicates that the tail of the distribution and the specification are an equal

distance from the overall average.

• A Cpk of less than one means that some of the data is beyond the specification limit.

• A Cpk greater than one indicates that the data is within the specification.

• The larger the Cpk, the more central and within specification the data.

CPm process repeatability

Capability index that takes into account variation between the process average and the target. If the process average and the target are the same value, Cpm will be the same as Cpk. If the average drifts from the target, Cpm will be less than Cpk.

Skewness

negative

An asymmetric frequency distribution is skewed to the left if the lower tail is longer than the upper tail, and skewed to the right if the upper tail is longer than the lower tail. Distributions of positive-valued random variables values are often skewed right.

Kurtosis

Kurtosis is a parameter that describes the shape of a random variable’s probability distribution.

The graphs on the left illustrate the notion of kurtosis. The lower curve has higher kurtosis than the upper curve. It is more peaked at the center, and it has fatter tails

6.1 Instrument configuration

TPO or TPA calculation (portable instrument)

The TPO (Total Package Oxygen) and TPA (Total Package Air) features are available on the portable instrument for an EC sensor measuring oxygen (refer also to the table in Generic terms and definitions

on page 111 for an explanation of these two terms).

To initiate these options, the instrument must be configured in “Sample mode” (see TPO and TPA

parameters (portable instrument)below) and the TPO or TPA calculation must be enabled (see Advanced configuration - EC sensor on page 55).

The operator also needs to ensure the package is shaken for about 5 minutes before measuring, and to know the total volume of the package and the total volume of the contents of the package.

Continuous mode or sample mode (portable instrument)

Continuous mode is typically used for process measurement, whereas sample mode is aimed at lab measurements of small volume individual samples such as cans, bottles, etc. The measurement mode is a parameter defined for the entire instrument, not for each channel.

Continuous mode cycle

• Every 2 sec. measurements are refreshed on the display

• The relays and the analog outputs are updated

• Measurements are continuously stored in memory (volatile and non volatile memory) according to

individual settings

Sample mode cycle (portable instruments)

When the user wants to measure a sample:

• He prepares the sample

• He starts the measurement

• Measurement is stopped when all active channels have reached their "stop criteria" (defined in the

channel configuration screen - see details in Stop criteria configuration (portable instrument) on

page 53). The measurement value is stored according to individual settings. If the channel is

configured for TPO or TPA calculation the user must enter the respective parameters (see TPO and

TPA parameters (portable instrument) on page 53)

• The user can then start a new measurement Continuous or sample mode selection

• Select Measurement mode:

• Continuous mode for on line process

• Sample mode for lab sample analysis (portable instruments only)

• Selection of units for barometric, external pressure and temperature Sample mode measurements (portable instrument)

When the numeric view is selected, the normal measurement window is displayed. Press the function key (on the header bar) to initiate the sample measurement.

The text "In progress" and the measurement value are displayed sequentially. The measurement process stops when the stop criteria selected are fulfilled. See Stop criteria configuration (portable

instrument) on page 53

The measurement process is stopped when:

• The "stop criteria" is fulfilled, typically when the gas concentration reaches the set threshold

• The function key has been pressed

• The "Maximum time" criteria is reached

• An error has occurred (e.g. sensor out)

When the sample measurement stops because the stop criteria are fulfilled, the gas concentration and temperature are no longer refreshed. They indicate the measurement when the stop criteria was reached. If the channel was configured for TPO or TPA calculation, enter the parameters (see TPO and

TPA parameters (portable instrument) on page 53).

Note: The mini graph is continuously refreshed.

If the sample mode is stopped for another reason (user abort, max. time, or measurement error), the “aborted” message is displayed. The reason for the stop is explained when the icon is pressed (as with any event).

Page 55

Measurement Menu

TPO and TPA parameters (portable instrument)

The parameters required for TPO and TPA calculation are the same.

• Overflow volume: Total package size

• Net content volume: Volume of liquid in the package

Press the Compute button to calculate the TPO or TPA. The parameters can be changed and the value recalculated if necessary.

TPO values are displayed in ppm, TPA values in mL. To store the measurement, press the OK button.

Stop criteria configuration (portable instrument) Press the Stop criteria button.

Note: The parameters available for configuration depend on the type of stop criteria being defined.

Available in “Sample measurement mode” (see Instrument configuration on page 52), this setting allows configuration of the stop criteria for each channel:

• Above threshold: The stop criteria is met when the gas concentration is greater than the parameter

entered in "Threshold”

•Below threshold: The stop criteria is met when the gas concentration is lower than the parameter

entered in "Threshold”

• Stability: The stop criteria is met when the variation of the gas concentration is smaller than the

parameter entered in "Variation"

•Time: The stop criteria is met when the elapsed time reaches the “Max. time” parameter.

Note: The number of samples taken into account to compute the "Variation" can be adjusted using the parameter "Depth".

• The parameter "Max. time" is the maximum time allowed to reach the target. If “Time” is not the type

of stop criteria, then when this delay has elapsed, the measurement stops and the message “aborted” is displayed.

• The time filter allows you to filter the stop criteria. The sample mode is stopped when the stop criteria

is fulfilled for a time greater than the parameter "Time Filter". As an example, if criteria is set to "Above threshold" and “Time Filter” is set to 10 sec. the

measurement stops when the gas concentration is above the "Threshold" for more than 10 seconds.

6.2 Measurement configuration

EC sensor

• Sensor’s membrane number selection

•Medium: Liquid or gas phase.

• Gas unit type: Partial, Fraction, Dissolved.

• Gas unit: The list of available units depends on unit type selected above.

Note: This is the gas concentration measured by the EC sensor. When a composite unit is selected (e.g. ppm-ppb) the unit will change depending on the range of the value to display.

•Liquid: When medium is liquid, select water or a liquid with a different solubility (if available).

• Display resolution: Maximum resolution depends on gas, membrane and unit. A maximum of 5

digits can be displayed. Decimals can be limited to 0, 1, 2 or 3 decimals for easier reading. That does not affect the actual resolution of data measured and stored, but only the data displayed.

• Thermal cutoff: To protect the sensor, the thermal cutoff function allows for setting a sample high

temperature limit. If exceeded (during a Cleaning In Place cycle for example) the electrical signal to the sensor is cut off, the measurement session is suspended and the system displays a “HOT” alarm message. The system resumes when temperature drops to 90% of the specified cutoff temperature.

• Thermal cut off options: Disabled / enabled.

• Thermal cut off temperature: To be set according to conditions.

TC sensor

The measurement configuration for a TC sensor is the same as for an EC sensor with the addition of one extra selection criteria:

• Purge gas: From the drop-down list, select the purge gas being used for the TC sensor.

Page 56

Measurement Menu

Measurement alarms configuration

Set the thresholds for the low/high concentration levels, according to the application. Each alarm type can be individually enabled or disabled without losing its settings.

These events can activate the relays and can be displayed.

•Low-low: 2nd stage for too low concentration

•Low: 1st stage for too low concentration

•High: 1st stage for too high concentration

• High-high: 2nd stage for too high concentration

•Hysteresis: A percentage of the above concentration values. The hysteresis is used to prevent relay

• Delay: The delay in seconds, before alarms go on whenever concentration values go above ”High

“flickering” when the measurement is just at the alarm levels. Set this to a minimum, but enough to eliminate flickering.

As an example, if the High Alarm is set to 40 units and the Hysteresis is set to 10%, then the High Alarm is activated once the measurement reaches 40 units, but only deactivated once the measurement drops below 36 units. With the Low Alarm the opposite is true, in that if the Low Alarm is set to 20 units and the Hysteresis set to 10%, then the Low Alarm is activated when the measurement drops below 20 units, and deactivated when the measurement rises above 22 units.

alarms” or below “Low alarms”. Set this to a minimum value, but enough to avoid alarms for non-representative peaks beyond the set level.

Figure 33 Alarms system diagram

Measurement filter configuration

The filters are aimed at “flattening” the measurement curve in situations where the process shows atypical peak values that could otherwise hamper the interpretation of measurement readings. The filter is applied on the last set of measurements each time a measurement is taken.

•Mean: Mathematical average of the last set (depth) of measurement values.

• Median filter: Allows for eliminating atypical peak measurement values, and average the remaining

ones. The calculation sorts the last measurements set (depth) by values, then delete the highest and lowest values, and averages the remaining values (central depth).

Example for depth 7, central depth 5: Sorted values, both ends eliminated, the average of the center five is then 3.88.

0.7 - 1.1 - 4.0 - 4.3 - 4.4 - 5.6 - 7.0

Example for depth 5, central depth 3: Sorted values, both ends eliminated, the average of the center three is then 4.23.

1.1 - 4.0 - 4.3 - 4.4 - 5.6

Example for depth 8, central depth 4: Sorted values, both ends eliminated, the average of the center four is then 4.43.

0.7 - 1.1 - 4.0 - 4.3 - 4.4 - 5.0 - 5.6 - 7.0

Note: If you believe you need to enable these corrections, it is advisable to contact a Hach Lange Service Representative first.

Interferences configuration

These options are available to take into account the influence of some components or gases in the sample during measurement. All available interference corrections are disabled by default.

The following interference corrections are available:

• For oxygen measurements - CO

• For hydrogen measurements - Temperature, H2O, He, O

• For nitrogen measurements - Temperature, H2O, O2, H

, H2S, Chlorine, Salt, H

Note: If you believe you need to enable any of the above, it is advisable to contact a Hach Lange Service Representative first.

Interferences in oxygen measurement

In some applications, like in the beverage industry, there can be high concentrations of carbon dioxide in the sample. Hach Lange recommends using the CO2 interference option if a carbon dioxide concentration of over 1% in gas phase, or 15 ppm in dissolved phase is present.

In the petroleum industry, the detection of oxygen is sometimes hampered by significant concentrations of hydrogen sulfide in the sample. Hach Lange recommends using the H

interference option if the hydrogen sulfide concentration exceeds 0.15% in gas phase, or 5 ppm in dissolved phase. To operate the oxygen sensor in these conditions requires using a di fferent sensor and electrolyte. When using this mode your system will experience sensitivity loss of about 50 times higher than the minimum sensitivity for the membrane.

The instrument can also compensate for the presence of high hydrogen levels in the sample.

• CO2 or H2S: Select CO

, H2S or All disabled.

• Chlorinity/Salinity: Select Chlorinity, Salt or All disabled. For chlorinity or salt, it is required to

enter the actual concentration in the sample.

•H2: Select H

partial pressure of H

enabled or disabled. It is required to enter the interfering gas pressure, which is the

in the sample.

When enabled, the H2 interference must be calibrated. See Interference calibration (EC sensor) on

page 64. A warning pop-up window is displayed to remind the user of this action.

Page 58

Measurement Menu

Interferences in hydrogen measurement

The presence of oxygen in the sample can have an effect on the hydrogen sensor to varying degrees, depending on the membrane being used. The oxygen correction option enables the instrument to correct for this condition.

• Temperature compensation: If there is a significant fluctuation in the sample temperature

• Interfering H2O: This only applies to measurements taken in 100% humid gases or in traces of

• Interfering O2: If the sample is known to contain oxygen, check this box.

The instrument can also compensate for the presence of helium in the sample.

• Temperature compensation: As described above.

• Interfering H2O: As described above

• Interfering He constant: If helium is the interfering gas enable this option to allow the instrument

• Interfering He: If the sample contains a known concentration of helium, check this box and enter

Interferences in nitrogen measurement

The presence of oxygen in the sample affects the nitrogen sensor. Oxygen produces about three times the effect of an equivalent amount of nitrogen in a TC sensor causing a comparably erroneous displayed value. For example, a properly calibrated nitrogen sensor, placed in air having 80% nitrogen and 20% oxygen would, uncorrected, display approximately 140% nitrogen (80% + 3*20%).

In the beverage application there is often little oxygen present, and this interference can be ignored. However, if this simplification cannot be made use this oxygen correction option to enable the instrument to correct for this condition.

• Temperature compensation: If there is a significant fluctuation in the sample temperature

• Interfering H2O: This only applies to measurements taken in 100% humid gases or in traces of

Measured data storage

There is one measurement file per channel which contains the data generated by the measurement cycle. The measurement files are updated in volatile memory, and regularly copied in non-volatile memory (file back-up). At start up, the measurement files in volatile memory are updated with the files from the non-volatile memory.

Note: When the measurement file is full, it is managed as a First in-First out buffer.

This dialog box allows adjustment of the parameters for recording and storing measurements. Two storage mode selections are available depending on the measurement mode selected (see Instrument

configuration on page 52).

Storage modes in continuous measurement mode:

• No storage

•Store once: When the volatile memory is full (10,000 positions), the recording of measurement stops

• Rolling buffer: When the volatile memory is full, the latest measurement set replaces the oldest one

continuously (first-in, first-out)

Storage modes in sample measurement mode:

• Only final measurement: The measurement when the stop criteria are met is saved (one per

sample)

• Only when sample mode started: The measurements when the sample mode is started are saved.

• All measurements: All the measurements are stored continuously.

Note: Data stored in volatile memory are lost when instrument is off, non-volatile memory is permanent. In case of an accidental power off event, the instrument resumes measurement storage after the last measurement stored in flash.

• RAM time (volatile memory): Delay in seconds between two recordings of measured data.

• FLASH time (non-volatile memory): Delay in seconds between two data file transfers from volatile

memory into non-volatile memory. The last data file erases the previous one. This field is only available if the Auto save in flash box is checked.

• Save in flash now: Press this button to store measurement data in flash (non-volatile memory)

immediately. After pressing this button, press OK to initiate the process. A warning screen appears informing you that the operation can take up to 30 seconds. Press Yes to continue with the process, or No to abort.

• Auto save in flash: Check this box to save measurements in flash (non-volatile memory)

automatically. Measurements are saved at regular time intervals as defined in the FLASH time box.

• Start logging measurement: Store once mode. Starts and stops the measurement recording

session. Measurement recording is stopped when the buffer is full.

• Purge data: Clear all data for all channels in the volatile and non-volatile memories.

• Open data 1, 2, or 3: Opens a table showing the measured values which are stored in the volatile

memory (RAM). Use the scroll bar at the right to move to another data range (the id range will be shown in the title bar). The page number being viewed and the total number of pages are shown at the bottom.

Use the keys at the bottom to move directly to the first page, previous page, next page or last page.

Note: If TPO or TPA calculation is enabled, a ”TPO data” or a ”TPA data” button will be available underneath the “Open data” button described above. Pressing this button will display the TPO or TPA calculated data in a screen similar to that for standard data.

7.1 Definitions

Definitions

We define 2 types of calibration:

• the calibration of the gas to measure (e.g. O

• the calibration of interferences (e.g. H2O for a CO2 sensor)

To calibrate the gas to measure (main gas), the user usually puts the sensor in the main gas without any interfering gas.

To calibrate the interferences, the user usually puts the sensor in the interfering gas without any of the main gas.

Calibrations can only be performed once the instrument has been installed, configured and each channel has been set up. You must also ensure that you have the correct access rights to access the calibration menu (minimum of level 2 for sensor calibrations and level 3 for barometric pressure calibration).

Select sensor calibration from the calibration menu, then select the channel to calibrate. There are two types of gas sensor calibration available, depending on the gas being measured and the

type of sensor being used:

1. In Air: For Oxygen and Ozone with an EC sensor.

2. Direct value: Any gas with either an EC or TC sensor. This calibration exposes the sensor to a gas

Note: All the calibration information for a smart EC Sensor is stored in the sensor’s memory. When a smart sensor is connected to the instrument for the first time, a calibration report (see example in

Calibration reports on page 66) is automatically generated giving the details of the last calibration.

If the sensor being calibrated is an EC sensor, follow the instructions in the next section entitled EC gas

sensor calibration. For TC sensors, refer to TC gas sensor calibration on page 63.

Note: When calibration is started, a calibration event is set, and the analog output and relay are put on hold (if selected below) to avoid unwanted alarms or potential process problems. This resumes when calibration is finished.

• Calibration mode: 2 types available, depending on the gas being

measured:

• Direct value: Any gas

•In Air (default): For O

•Medium: Select liquid or gas (direct calibration only)

• Concentration unit type: Partial, fraction or dissolved (dissolved is

• Concentration unit: The list of available units depends on unit type

selected above.

•Liquid: Select as appropriate, available when liquid has been selected in medium (above).

• Enter the gas concentration according to the value in the calibration media, when direct value is used

• Hold during calibration: On by default, this stops any output from the instrument during the calibration process to avoid sending invalid information to any connected device.

• Interference enabled : If selected, this takes into account the influence of interferences (see settings below) during calibration. By default the same interference as during measurement is selected.

which is continually refreshed. The value “% ideal current” is a percentage of the current against the ideal

current for the membrane type selected. If this percentage is not within the accepted range, an error message is displayed and the calibration process fails (see Calibration errors (EC and TC sensors) on page 64). A warning message can be displayed when this value is close to the boundaries, but when calibration can be accepted.

The message is first displayed in the result box. The dialog box with the error message or the warning is displayed when the finish button is pressed.

The value “% last calibration” shows the ratio between the current measurement and the previous sensor calibration.

The value “% variation” indicates the variation during the last 3 measurements, which is the stability of the measurements. A variation as low as possible is needed for a precise calibration.

The display shows the actual calibration parameters, and the actual readings (temperature, barometer, current).

Note: In case of calibration failure, consider replacing the membrane. See the sensor maintenance manual for details.

7.2.1 O2 sensor calibration

O2 sensor calibration

The O2 sensor needs to be calibrated after each sensor service. Wait at least 30 minutes after mounting a new membrane before recalibrating. The sensor is in contact with either:

• Air at atmospheric pressure (In Air) at known concentration (Direct value). The gas can be dissolved or not.

• O

In air calibration This calibration procedure places the O2 sensor in water-saturated air, to

water. Shake off any excess water, but leave a few drops inside the cap. Verify that the screw-on protection cap is in place on the sensor head. If you use a Dacron mesh inside the protection cap, make sure it is dry before attempting to calibrate. Then, loosely place the storage cap back on the sensor, holding it in place with a few turns of its collar.

Set the calibration parameters accordingly (see Modify calibration

parameters on page 61), and press calibrate.

Similarly, if only the calibration value has changed, then this can be updated directly instead of pressing the Modify button.

• Gas Phase: Select liquid or gas (direct calibration only)

• Gas unit type: Partial, fraction or dissolved (dissolved is for

calibration in a liquid only)

•Gas unit: The list of available units depends on unit type selected

above.

•Liquid: Select as appropriate.

• Enter the gas concentration according to the value in the calibration

media.

• Hold during calibration: On by default, this stops any output from the

instrument during the calibration process to avoid sending invalid information to any connected device.

• Automatic calibration stop: If selected, when the stability criteria is

reached, the calibration process stops automatically.

• Interferences enabled: If selected, this takes into account the influence

of interferences during calibration. By default the same interferences as during measurement are selected.
