Eagle Ray Digital Water Tester Full FAQ List

If you're using the Eagle Ray Digital Water Testing Kit for your pool or spa, you already know how convenient and fast it makes testing your water. But like any tech, it comes with questions, especially the first time you use it.

Below, we’ve rounded up the most common questions and clear, friendly answers to help you get the most out of your device.

Eagle Ray Testing Device FAQs

Why am I getting a “Light Error” on the Eagle Ray?

The “Light Error” usually means the device is having trouble reading the strip. Here’s how to fix it:

• Press and hold the down arrow to remove the black table

• Gently clean the white reference pad using a soft, dry cloth

• Reinsert the black table by pressing the up arrow

• Retest with a new strip, and insert it quickly after dipping it into the water

This usually clears things up right away.

My test readings seem off or inconsistent. What should I do?

When your results don’t make sense, it's often due to a few fixable factors:

• Always use a new test strip and insert it into the device within 3 seconds of dipping

• Make sure your strips haven’t been exposed to air or moisture

• Clean the carrier stage and the reference pad to prevent buildup

• If you’re still getting strange results, try resetting the device

Why do my test readings vary slightly each time I use the Eagle Ray tester?

Small differences in readings are completely normal with any digital water tester. Factors like lighting, test strip age, and minor sampling differences can cause slight variations.

How do I reset or calibrate the Eagle Ray?

Resetting is simple:

• Take out the batteries and wait for at least 60 seconds

• Put the batteries back in

• Press and hold the small reset button on the back of the device

After it restarts, test with a new strip to complete the reset process.

How should I clean the white reference pad?

Use a soft, lint-free cloth and gently wipe the pad clean. Avoid using water, alcohol, or any cleaners. These can interfere with the accuracy of your readings.

My device won’t turn on. What should I check?

First, make sure you’re using a fresh 1.5V AA dry cell battery, ideally 1.63V or higher. Check for signs of water exposure, especially around the battery compartment. If the power button seems stuck, it might be due to tight internal screws near the switch. If that’s the case, reach out to support for help.

Can I use test strips from other brands?

No. Eagle Ray is calibrated specifically for its own test strips. Using third-party strips can lead to incorrect readings and error messages.

How long do the test strips last, and how should I store them?

They’re good for 12 months from the manufacturing date. Keep them in a tightly closed container in a cool, dry spot away from moisture, heat, or direct sunlight.

Device Error Messages

What does the "rec fulling" message mean?

This message simply means the device's internal memory is full and cannot store additional test results. Your test will still complete normally, but new results will not be saved unless memory is cleared.

How can I clear the "rec fulling" message?

To remove this message, you’ll need to clear stored results. Refer to your device’s manual for how to reset or manage stored data. If you prefer not to store test history, this message can be safely ignored. It won’t impact test accuracy.

Device Operation & Maintenance

The tray doesn't retract when I turn the device off. What should I do?

If the test strip tray doesn't retract on shutdown, try gently powering the device back on, waiting a few seconds, and then turning it off again. If it still doesn’t retract, manually guide it back into place without forcing it.

Can I manually adjust the strip holder tray?

Yes! If the strip holder isn’t aligned properly, you can gently move it back to the correct position. Make sure the device is powered off before adjusting.

How can I change how long the device stays on before shutting off?

You can adjust the auto shut-off time in your device settings. This helps conserve battery life if you prefer shorter or longer operating times between uses.

What is the mini USB port on the EagleRay tester for? Should I use it?

The mini USB port located at the top of your EagleRay device can be used to power the tester by plugging it into a USB power source like a wall adapter, power bank, or computer.

However, please note:

• The USB port does not charge the tester’s batteries
• It only powers the device while it’s actively plugged in
• Once unplugged, the device will shut off unless batteries are installed

While the USB port can be helpful for stationary use or in a pinch, we recommend using batteries as your primary power source so you can move freely and use the tester anywhere. No cords required.
