Method Menu
Save up to ten channel-specific methods in the Method menu for fast and easy recollection of custom channel-specific measurement, calibration and alarm settings.
The default method (M100 or M200) is updated whenever the channel-specific measurement, calibration and alarm settings are changed in the Mode and Settings menu and the default method is not password protected.
The custom methods (M101-M110 or M201-M210) can be protected using a three to eight digit password. When a protected method is created, loaded and active in the measurement mode and a calibration is performed, that calibration will be saved to the method so every time the method is loaded, the corresponding calibration will also be loaded.
Protected methods are helpful when using two or more electrodes on one channel. For example, a pH electrode and an ion selective electrode (ISE) used on the same BNC input of the Star A214 pH/ISE meter or a low range conductivity sensor and standard range conductivity sensor used on the same 8 pin MiniDIN input of the Star A212 conductivity meter.

Buffer Group Setting
Orion Star A211 pH meters, Orion Star A215 pH/conductivity meters and Orion Star A216 pH/RDO/DO meters are capable of automatically recognizing pH buffer values within the selected buffer set during a pH calibration. During the pH calibration, the meter uses the selected pH buffer set and the raw mV reading of the pH electrode in the buffer to recognize and display the buffer value at the measured temperature. The raw mV reading of the pH electrode in the buffer must be within one pH unit (approximately ±59 mV) of the buffer’s theoretical mV value for the meter to recognize the buffer.

Testing a pH Electrode for Automatic Buffer Recognition
Use the following procedure to verify that the raw mV reading of the pH electrode is within one pH unit (±59 mV) from the theoretical mV reading of the pH buffer, and therefore verify that the pH electrode in use is capable of performing automatic buffer recognition.
1. Prepare the pH electrode according to the electrode manual. Set the meter measurement mode to mV.
2. Rinse the pH electrode with distilled water, blot it dry with a lint-free tissue and place the pH electrode into a pH 4.01 buffer at approximately 25 °C.
3. Wait for the measurement to stabilize and record the mV value of the pH 4.01 buffer when the measurement is stable.
4. Remove the pH electrode from the pH 4.01 buffer.
5. Rinse the pH electrode with distilled water, blot it dry with a lint-free tissue and place the pH electrode into a pH 7.00 buffer at approximately 25 °C.
6. Wait for the measurement to stabilize and record the mV value of the pH 7.00 buffer when the measurement is stable.
7. The mV reading of the pH electrode in pH 4 buffer should be +117 to +236 mV and in pH 7 buffer should be -59 to +59 mV. If the mV readings are in the correct ranges, the pH electrode is capable of performing automatic buffer recognition. If the mV readings are not in the correct ranges, manually enter the pH buffer values during a pH calibration.

Buffer Group Setting
Orion Star A214 pH/ISE meters are capable of automatically recognizing pH buffer values within the selected buffer set during a pH calibration. During the pH calibration, the meter uses the selected pH buffer set and the raw mV reading of the pH electrode in the buffer to recognize and display the buffer value at the measured temperature. The raw mV reading of the pH electrode in the buffer must be within one pH unit (approximately ±59 mV) of the buffer’s theoretical mV value for the meter to recognize the buffer.
Blank Correct Setting
Orion Star A214 pH/ISE meters offer the option to use blank (non-linear) correction for ISE measurements when a multi-point calibration is performed. The automatic blank correction feature uses an algorithm to compensate for the non-linearity of an ion selective electrode in low level standards and samples.
With the blank correction feature enabled, the meter decides whether blank correction is the best measurement strategy by analyzing the electrode response during a multi-point calibration.
A separate blank does not have to be run. Graphically, blank correction is equivalent to drawing a smooth curve through the lowest three points of the multi-point calibration and extrapolating to zero concentration based on the assumption of Nernstian electrode behavior.
Multi-point calibrations at the lower limit of detection are desirable when the response of an ion selective electrode is non-linear and cannot be characterized with a one or two point calibration.
This is usually seen as a low electrode slope. Generally, the electrode is behaving in a
Nernstian manner but the effect of a blank is being observed. See the figure below.
Thermo Scientific
This blank may be a true reagent blank, traces of analate ion in the reagents or it may be the
“mud” value of the electrode. It could also be an interference in the reagents that becomes apparent at low levels of analate ion, or it could be any combination of these effects. The expanded version of the Nernst equation traditionally used for blank correction is as follows:
E = E
0
+ S * log (C + b) where b is the blank
Orion Star A210 Series Benchtop Meter User Manual |

In a multi-point calibration, a set of equations is generated and the relationship between them evaluated. For example, the equations generated in a three point calibration would be:
E

= E
0
+ S * log (C

+ b)
E

= E

+ b)
The meter evaluates the relationships between the three potentials E
1
, E
2
and E
3
and the three concentrations C
1
, C
2
and C
3
. If the relationships indicate that blank correction is desired, a blank will automatically be calculated and the non-linearity will be corrected for in a Nernstian manner. If the appropriate conditions are not met, the blank is set at zero and each segment of the multi-point calibration is treated independently.
When all three of the following conditions are met, blank correction is invoked.
1. The concentration of the first standard is zero, or the slope of the electrode between the first and second standards is less than the slope between the second and third.
2. Potential differences between points are significant. For example, E
3
- E
1
> 10 mV
3. The blank correction algorithm converges at reasonable blank and slope values. Conditions in steps 1 and 2 prevent failure to converge in most situations. However, the slope will attain any value necessary for convergence to a calculated blank value of 3 x C
3
.
When blank correction is implemented, the slope value for the electrode may be outside the range of values normally considered acceptable during an ordinary calibration. For best results, calibration standards should be close in range to the expected sample concentrations and should bracket the expected sample concentration. When conditions 1, 2 and 3 are not met, the calibration data is handled by the multi-point calibration method described earlier.
In calibrations with more than three points, a combination of methods is utilized. Automatic blank correction is used if the lowest three points satisfy the criteria and multi-point calibration is used for the other points. The slope calculated in the automatic blank correction algorithm and the slopes for each additional segment are used to calculate the average slope.
Low Level Stability Setting
Orion Star A214 pH/ISE meters offer the option to use the low level stability feature when calibrating ion selective electrodes. The low level stability feature improves the accuracy of low concentration ISE measurements by adjusting the timing for calibration points of low level standards, allowing a longer stabilization time for the electrode in the calibration standards. The stabilization time is typically extended to about three to five minutes per calibration point, but will vary based on the actual readings from the electrode during calibration.

Reference Temperature, Temperature Compensation and Coefficient Settings
Orion Star A212 conductivity meters and Orion Star A215 pH/conductivity meters offer several options for temperature compensated conductivity measurements. Temperature has a large effect on the conductivity value of a solution. The temperature compensation feature allows the meter to use the sample conductivity and temperature readings to calculate and display the conductivity that the sample would be expected to have at a selected reference temperature, such as 25 °C. To accurately use the temperature compensation feature, select the proper type of temperature compensation for the samples to be measured; set the required reference temperature as 5 °C, 10 °C, 15 °C, 20 °C or 25 °C; and use a conductivity sensor with built-in
ATC temperature probe. The options for temperature compensation are:
·
Linear – uses the temperature coefficient value to apply a constant percent correction factor to every degree change in temperature. A few common linear coefficient values are:

· nLFn (non-linear ultra pure non-degassed water) – applies a non-constant correction factor to pure water samples that have a varying response to changes in temperature. This mode is for temperature compensated readings of low conductivity waters that are in equilibrium with the carbon dioxide in air, such as pure waters reading near 1 μS/cm at 25 °C and natural waters having a composition comparable to natural ground, well or surface waters.
· nLFu (non-linear ultra pure degassed water) – applies a non-constant correction factor to pure water samples that have a varying response to changes in temperature. This mode is for temperature compensated readings of ultra pure water that contains no air and no carbon dioxide, such as ultra pure water (18 megohms resistance or higher) directly from the source without aeration.
· EP – no temperature correction is applied (temperature compensation turned off) and a warning is displayed if the measured conductivity value is over the EP requirement for pure water at the measured sample temperature.
·
Off - no temperature correction is applied and the actual conductivity value is displayed at the measured sample temperature.

Salinity Type Setting
Orion Star A212 conductivity meters and Orion Star A215 pH/conductivity meters offer two salinity types: practical salinity and natural sea water. Practical salinity measurements are based on relating the sample measurement to the reading of a standard potassium chloride
(KCl) solution at 15 °C. Orion Star A210 series conductivity meters will automatically temperature compensate and report the expected practical salinity result as practical salinity units (psu) at 15 °C when using a conductivity sensor with built-in temperature. Natural sea water measurements use a historic convention known as UNESCO 1966 and Orion Star A210 series conductivity meters will report the expected natural sea water result as parts per thousand (ppt).
TDS Factor Setting
Orion Star A212 conductivity meters and Orion Star A215 pH/conductivity meters measure TDS as the total amount of dissolved inorganic material in a solution. The dissolved inorganic material carries a current that is measured by the conductivity sensor. Since there is a direct relationship between conductivity and TDS, conductivity readings are used to estimate the presence of inorganic material using the TDS factor entered in the setup menu.
The standard method of determining TDS involves evaporating a sample to dryness at 180 °C and weighing the residue. The TDS factor is calculated by taking the residue weight and dividing it by the sample conductivity. Subsequent conductivity readings are multiplied by the
TDS factor to determine the TDS value of the sample.
Cell Type Setting
Orion Star A212 conductivity meters and Orion Star A215 pH/conductivity meters accept 2-cell and 4-cell conductivity sensors and allows the type of conductivity sensor to be set as Standard
(most conductivity sensors) or USP (for the ultra pure water conductivity sensor, Catalog
Number 013016MD, when disabling temperature compensation).

Temperature Calibration
When using Orion Star A210 series benchtop meters, a temperature calibration can be performed on an ATC probe, conductivity sensor with built-in temperature or polarographic dissolved oxygen sensor with built-in temperature when the probe or sensor is connected to the meter. Use the temperature calibration function only when necessary, since the meter has a relative temperature accuracy of ±0.1°C and ATC probes have varying accuracies, usually
±0.5°C to ±2°C. Since the temperature offset calculated during the calibration is applied to all future temperature measurements, recalibrate the temperature if a different ATC probe is used.

Using the DO/RDO Channel
Use the Orion Star A213 RDO/DO meter or Orion Star A216 pH/RDO/DO meter to measure dissolved oxygen as percent saturation or mg/L and temperature using either Orion RDO optical or polarographic dissolved oxygen sensors. The following chapter provides instructions on connecting sensors, calibrating the system and measuring these parameters.
Meter and Sensor Preparation
1. Familiarize yourself with general meter operation and prepare the meter and accessories
according to the instructions in Chapter 2 Meter Basics .
a. It is recommended that sensors be placed in the meter-attached electrode stand for easy movement in and out of containers during calibration, measurement and storage.

Using the DO/RDO Channel
Dissolved Oxygen Calibration Procedure
Note: A polarographic dissolved oxygen sensor must be polarized prior to use. The polarographic dissolved oxygen sensor is continuously polarized when connected to the meter.
If the polarographic dissolved oxygen sensor is new, has been serviced or has not been connected to the meter – connect the sensor to the meter, power on the meter and wait 30 minutes for the sensor to polarize.
Orion Star A213 RDO/DO meters and Orion Star A216 pH/RDO/DO meters can perform the following calibrations:
·
Air (water-saturated air) – This is the simplest and most accurate method and uses the calibration sleeve included with most dissolved oxygen sensors. For best accuracy, the calibration temperature should match the expected sample temperature. Moisten the sponge in the calibration sleeve with distilled water and insert the sensor into the sleeve.
Alternatively, a BOD bottle can be used with just enough distilled water to cover the bottom without touching the sensor.
·
Water (air-saturated water) – This method uses water that is 100% saturated with air.
Bubble air into a water sample for an extended period, preferably overnight.
·
Manual (Winkler) – This method uses a water sample with a known concentration of dissolved oxygen and is typically used to calibrate the DO sensor to the value achieved by a Winkler titration. Due to possible titration errors, this method is inherently less accurate.
· Set Zero – This method uses an oxygen free solution to add a zero point to an existing
Water Saturated Air or Air Saturated Water calibration. This calibration is generally recommended when measurements are below 10% saturation or 1 mg/L.
Prepare the dissolved oxygen sensor according to the instructions in the sensor manual.
Connect all sensors to be used to the appropriate meter inputs.
Make sure the meter measurement mode is set to dissolved oxygen (DO or RDO). For Star
A216 meters, press the f3 (channel) key until the dissolved oxygen channel is shown in the measurement mode.

Troubleshooting Tips
If an issue is encountered while using the Orion Star A210 Series meter, ensure the correct power adapter is being used and try power cycling the meter: disconnect the power adapter from the meter, wait 15 seconds and reconnect the power adapter to the meter.
Meter Issue
The measurement value is flashing 9999 and displaying Over Range or
Under Range
The meter locks up while connected to a computer via the USB cable
The meter keypad is unresponsive when using the Star Com computer software
The measurement value freezes and will not change
Recommended Action
The measurement is outside the allowable measurement range. Verify that the correct channel is shown on the meter display. Make sure the electrode or sensor is fully connected with the meter.
Disconnect the USB cable from the meter and computer and then disconnect and reconnect the power adapter from the meter. Reestablish the meter and computer USB connection.
The keypad lock option is enabled in the Star Com computer program. To disable the keypad lock: in the Star Com program click the Settings icon, uncheck the box next to Keypad Lock and press the Save icon.
The meter display goes blank, shows random lines or intermittently freezes
The meter does not automatically recognize the pH buffer during calibration
The meter does not recognize the conductivity standard during calibration
The meter does not recognize an RDO optical or polarographic dissolved oxygen sensor
The read type is set to Auto-Read mode (AR icon shown on the display).
Press the measure (esc) key to take a new measurement or use the setup menu to change the read type to continuous.
Ensure the correct power supply for the Star A series meter is being used.
This power supply is different from the one supplied with Thermo Scientific
Orion Versa Star meters. The use of a surge protector or uninterrupted power supply (UPS) is also recommended. Perform a factor reset on the meter.
Verify the correct buffer set was selected in the setup menu. The meter uses raw mV readings to recognize the buffer. As the electrode ages or becomes dirty, its mV readings will drift. Check the buffers and clean the electrode according to the instructions in the electrode manual.
Verify that the correct nominal cell constant is entered in the setup menu for the conductivity sensor being calibrated. The cell constant is typically printed on the cable of the conductivity sensor. Verify that the conductivity standard is one that can be automatically recognized by the meter.
Recalibrate the conductivity sensor using new conductivity standard.
Make sure the dissolved oxygen sensor is fully connected with the meter and verify the correct channel is shown on the meter display. Wait about 15 seconds after connecting a dissolved oxygen sensor for the meter to recognize the DO sensor type. Press the measure (esc) key to initiate a new measurement and update the meter display.
