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 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.
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.
