Frequently Asked Questions - AD3000 Adwa
How do I calibrate the AD3000 pH meter?
To calibrate, first rinse the probe with distilled water. Then dip it in pH 7.01 buffer solution and press CAL. The meter will automatically calibrate. Repeat with pH 4.01 and pH 10.01 buffers for a multi-point calibration.
Why does the meter display 'Err'?
The 'Err' message usually indicates a problem with the probe. Check if the probe is properly connected, clean, and not damaged. If the error persists, replace the electrode.
How often should I calibrate the meter?
It is recommended to calibrate before each use, especially if measuring high-accuracy samples. At minimum, calibrate once a day.
Can I use the meter in liquids above 50°C?
No, the operating temperature is 0 to 50°C. Using it above 50°C can damage the probe and affect accuracy.
How do I store the pH probe?
Store the probe in a storage solution (e.g., Adwa pH electrode storage solution) to keep it hydrated. Never store in distilled water.
What type of battery does the AD3000 use?
It uses a standard 9V alkaline battery. Replace when the battery indicator shows low.
Is the meter waterproof?
The meter has an IP65 rating, meaning it is splashproof but not submersible. Avoid immersing it in water.
How do I replace the pH electrode?
Simply unscrew the old electrode from the BNC connector and screw on a new one. Ensure the O-ring is seated properly to maintain waterproof seal.
Can I measure ORP with this meter?
No, the AD3000 is a pH meter only. It does not measure ORP (oxidation-reduction potential).
What is the warranty period?
The AD3000 comes with a 2-year warranty against manufacturing defects. The pH probe is consumable and not covered under warranty.
