- Inspect sensor in bright light for cracks or flaws.

- Place 4.0 standard solution on sensor and attempt reading.  Failed sensors generally cannot read to the pH 4 solution. If so replace sensor.

- Test and/or replace batteries.  CR2032 3V Lithium batteries are available at most electronic retailers. Replace batteries when "B" shows on the display.

- Condition sensor.  Cover sensor in either standard solution and soak for 15 minutes.  Rinse and attempt calibration.
