Tipping Bucket Rain Gauge Calibration

• Enter zero in the Calibration Offset box
• Enter the Volume per Tip value as supplied by the manufacture of the rain gauge, into the Calibration Gain box. ~ for example:

• These Offset and Gain figures should now be written to the logger
• Click on the Write Unit, Scaling and Calibration values to the Logger button

To check the calibration

• Stop the logger, if it is running
• Select the Realtime screen
• Manually tip the bucket on the rain gauge 10 times
• Check that each tip shows as an increase in rain fall on the realtime screen

By default the Realtime screen updates every 2 seconds but this can be changed from the Options screen. You will have to wait for a Realtime screen update before the new rainfall values show on the rainfall gauge.
