3. Calibration Mode For All Meters

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 singleor multi-point calibration. You will need to set your meter to singleor 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.

17

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.

18

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.
