3.1 About Calibration

The 600 series meters are factory calibrated and allows you to measure pH/mV/ion/conductivity/resistivity/TDS/salinity/DO(%)/DO(mg/L) respective to the model(s) you have purchased. Calibrate to all measurement ranges to ensure the highest accuracy in any given measurement range. This should be done before you make measurements for the first time and also each time a new electrode is attached to the meter or when you suspect that the meter/electrode is out of calibration.

3.2 About Conductivity/ Resistivity/ TDS/ Salinity Calibration

Before measuring conductivity, resistivity, TDS or salinity, you will need to calibrate the meter with known conductivity, resistivity, TDS or salinity values.

The meter is capable of performing either automatic or manual calibration.

In the automatic calibration mode, the meter automatically detects and verifies the appropriate known calibration standards solutions being calibrated before accepting these particular calibration standards as one of its calibration values in a specific measurement range. This automatic calibration mode frees you from cumbersome calibration procedure.

The meter can perform a single- or multi-point calibration. You will need to set your meter to single- or multi-point calibration in the Setup mode for conductivity, resistivity, TDS or salinity.

Refer to the setup section for the particular mode you will be measuring. Instead of calibrating for TDS directly using TDS calibration standard solutions, you can have TDS calibration by using the conductivity calibration method and enter the appropriate TDS conversion factor into the meter.

For more information regarding TDS Conversion Factor determination, please go to the ‘Appendix’ of this manual.

3.3 Preparing the Meter for Calibration

Before starting calibration, make sure the meter is in the appropriate measurement mode.

For pH

Connect the pH probe to the BNC connector of the meter.

Be sure to remove the protective electrode storage bottle or rubber cap of the electrode before calibration or measurement. If the electrode has been stored dry, wet the electrode in clean water for 10 minutes before calibrating or taking readings to saturate the pH electrode surface and minimize drift.

Wash your electrode in clean water after use, and store in electrode storage solution. If storage solution is not available, use pH 4.01 or 7.00 buffer solution. Do not reuse buffer solutions after calibration. Contaminants in the solution can affect the calibration, and eventually the accuracy of the measurements.

It is recommended that you perform at least a 2-Point Calibration using standard buffers that adequately cover the expected measurement range, prior to measurement.

For Ion

Connect the ISE to the BNC connector of the meter.

Remove plastic protective cap of ISE. Briefly rinse the electrode with clean water to remove any residues. Rinse ISE before and after each calibration or sample measurement to avoid cross-contamination. Ensure that you use new or fresh standard solutions during calibration. Do not reuse Ion standard solution as it may be contaminated and affect the calibration and accuracy of measurements.

For Conductivity

Connect the conductivity probe with built-in temperature sensor into the 8-pin connector of the meter.

For best results, select a standard value close to the sample value you are measuring. Alternatively use a calibration solution value that is approximately 2/3 the full-scale value of the measurement range you plan to use. For example, in the 0 to 2000 µS conductivity range, use a 1413 µS solution for calibration.

Perform calibration for all measurement ranges to ensure the highest accuracy throughout all measurement range.

If you are measuring in solutions with Conductivity lower than 100 µS/cm or TDS lower than 50 ppm, calibrate the meter at least once a week to ensure accuracy. If you are measuring in the mid ranges and you wash the electrode in de-ionized water and store it dry, calibrate the meter once a month. If you take measurements at extreme temperatures, calibrate at least once a week.

Ensure that you use new conductivity standard solutions or sachets during calibration. Do not reuse standard solutions as it may be contaminated and affect the calibration and accuracy of measurements. Use fresh calibration solution each time you calibrate your meter. Keep solutions in a dry and cool environment if possible.

For DO(%) and DO (mg/L) Calibration

Before starting calibration, make sure you are in the correct measurement mode and in the correct calibration sequence. The temperature and the %

Saturation calibration must be done first before attempting to do the mg/L (ppm) Concentration calibration.

Rinse the probe well in the de-ionized (DI) water or rinse solution and wipe the probe carefully taking care of the membrane.

Calibrate the meter in all the modes to ensure the highest accuracy throughout the DO measurement range. In % Saturation, the meter is able to perform either a one point calibration or a 2 point calibration. For one point calibration, it is recommended that you perform a 100% Saturation calibration in saturated air. If you opt for 2 point calibration, you can calibrate for 100% Saturation in saturated air and 0% Saturation using a zero oxygen solution.

All new calibration values will automatically override the existing data. It is recommended to calibrate the meter periodically and or if it is suspected to be inaccurate.

Always rinse the probe with either DI water or rinse solution before and after each calibration/sample measurement. When calibrating in air, make sure that any water droplets from the probe’s membrane are removed.

3.4 Accessing Calibration mode

2. Temperature Calibration

2.1 About Temperature Calibration

It is important to ensure that temperature calibration is carried out prior to pH, conductivity and DO calibration since temperature readings affect the accuracy of pH, conductivity and DO measurements. You need to perform temperature calibration only if the temperature value displayed on the meter is different from that of a calibrated thermometer or if cell constant setting is changed. A temperature offset calibration of ± 5 °C/± 9 °F from the default reading is allowed for ATC mode.

The built-in temperature sensor of conductivity and DO probes are factory calibrated. The built-in ATC probe of the conductivity cells can be used for temperature readout and compensation of the pH values. DO in mg/L is dependent on temperature, so it is first necessary to calibrate or verify the temperature reading. Calibrate the probes only if you suspect temperature errors may have occurred over a long period of time or if you have a

replacement probe. This procedure offers offset adjustment of the probe to ensure more accurate temperature measurement.

Use a thermometer you are certain is accurate to measure the temperature of your sample.

2. pH Calibration

2.1 About pH Calibration

When you re-calibrate your meter, previous pH calibration points are replaced on a point by point basis. For example, if you previously calibrated your meter at pH 4.01, 7.00, and 10.01, and you have now re-calibrated at pH 7.00, the meter retains the old calibration data at pH 4.01 and pH 10.01. The meter shows previously calibrated points in the display when the meter is in pH measurement mode. To completely re-calibrate the meter, or when you use a replacement probe, it is best to clear the previous calibration and re-calibrate the meter at all points.

The meter supports four internationally recognized standard buffer groups: USA, NIST, DIN & PWB. The default buffer group is USA.

The meter is capable of calibrating up to 6 points, depending on the standard buffer selected. When completely re-calibrating the meter, the first point of calibration should be one of the following, depending on your choice of standard buffer group.

Buffer

Group

USA pH 7.00 pH 1.68, 4.01, 10.01, and 12.45

NIST pH 6.86 pH 4.01, 6.86, 9.18, and 12.45

DIN pH 6.79 pH 1.09, 3.06, 4.65, 9.23, and 12.75

PWB pH 6.97 pH 4.10

The meter automatically recognizes and calibrates to these standard pH buffer values, which makes pH calibration faster and easier.

4. About TDS

4.1 Calculating TDS Conversion Factor

You can calibrate your meter using TDS calibration standard solutions. The calibration standard only needs to give the TDS value at a standard temperature such as 25 °C. To determine the conductivity-to-TDS conversion factor use the following formula:

Factor = Actual TDS ÷ Actual Conductivity @ 25 °C

Definitions:

Actual TDS: Value from the solution bottle label or as a standard you make using

high purity water and precisely weighed salts.

Actual Conductivity: Value measured using a properly calibrated Conductivity/Temperature meter.

Both the Actual TDS and the Actual Conductivity values must be in the same magnitude of units. For example, if the TDS value is in ppm the conductivity value must be in µS; if the TDS value is in ppt the conductivity value must be in mS.

Check your factor by multiplying the conductivity reading by the factor in the above formula. The result should be in TDS value.

4.2 Calculating Temperature Coefficients

To determine the temperature coefficient of your sample solution use this formula:

Where:

tc = Temperature coefficient 25 = 25 °C

= Conductivity at Temp 1 CT2 = Conductivity at Temp 2

= Temp 1 T2 = Temp 2

Note: A controlled temperature water bath is ideal for this procedure

1. Immerse the probe into a sample of your solution and adjust the temperature coefficient to 0%

2. Wait for 5 minutes. Note T1 and CT1 (conductivity at T1).

3. Condition the sample solution and probe to a temperature (T2) that is about 5 °C to 10 °C different from T1, and note the conductivity reading CT2.

Note: Record your results for future reference. Ideally T1 and T2 should bracket your measurement temperature, and should not different by more than 5 °C.
