Frequently Asked Questions

What is factory calibration mode?

Your meter is in the factory calibration mode and is set to measure water and water-like fluids if it shows FAC or PRESET in the top right corner.

What is the best way to test the accuracy of a meter?

Your calibration can be easily tested by filling up a container. Start by resetting your batch total to zero. Then, start the flow and fill up the container. You should see '5.00 gallons' on your display if you filled up a 5-gallon container.

What is the expected lifespan of the lithium batteries of G2, A1 and TM meters?

Approximately 9000 hours.
