Please follow up below steps to proceed
the calibration:
Option1: Using TDS standards
1.
2.
Insert the probe into demineralized
or distilled water for about 30 minutes
to rinse the probe.
Select the TDS standard for calibration.
The factory default setting of the TDS
conversion factor is 0.50. If your
solution has a different TDS factor,
you can improve the calibration
accuracy by setting the TDS factor
before starting the calibration.
To converse the TDS factors to the
correct value, please see Appendix
B or refer to the value provided by
standard solution manufacturer.

5. Rinse the probe into one of the
containers. Gently stir the probe.
6. Dip the rinsed probe into the other
container. Tap the probe on the bottom
of container to remove air bubbles.
Let the probe stabilize to the solution
temperature.
