Calibrate your meter

A step-by-step guide to get your meter reading accurately.

Step 1 of 4
Which meter do you have?
Find the model number printed on the front of your meter and tap it below.
Step 2 of 4
Your starting calibration setting
Before you run your first test, confirm your meter is set to this value.
Model:
Starting Calibration Setting
1.000
This is the factory default. All meters ship set to 1.000.
💡
How to check your current setting: Press and hold DISPLAY for 3 seconds to open the settings menu. Press CALIBRATE to cycle through to the calibration coefficient field. The current value will flash on screen. Wait 5 seconds without pressing anything to exit without making changes.

Run a test and enter your readings
Pump a measured amount through your meter, then enter both numbers below.
Model:
Current setting:1.000

Before pumping: Press CALIBRATE for 1 second to reset the batch counter to zero. Pump at least 5 gallons (or 20 liters) for the most accurate result.

Want to fine-tune further?

Run another test with your new setting active. If the meter still reads a little off, you can calibrate again — your new setting becomes the starting point for the next pass.
