Frequently Asked Questions

Q: How do I calibrate the EC/TDS-TRA-600 transmitter?

Enter the CAL- menu, select your standard solution value (e.g., 1413 uS), immerse the electrode for 5 minutes, and save the value once the display stabilizes.

Q: What is the best way to install the conductivity probe?

Install the probe facing the flow direction and deep into the flow to avoid air bubbles or stagnant water, which can cause measurement inaccuracies.

Q: Can this instrument be used for high-purity water?

Yes, but high-purity water requires airtight, flow-through cells because exposure to air allows CO2 to dissolve, which drastically alters conductivity.

Q: How do I resolve unstable display readings?

Check for air bubbles in the pipeline, verify that the electrode connections are secure, and ensure the water quality source is stable.

Q: How should the electrodes be maintained?

Avoid wiping the platinum black coating. For cleaning, soak the electrode in 10% dilute hydrochloric acid briefly, then rinse thoroughly with pure water.

Q: What output signals does the TRA-600 support for automation?

It supports 4-20mA current output for analog control and RS485 for digital communication, allowing integration with most industrial PLCs.
