Field checking using a reference instrument - RFL100

You can perform a field check of the RFL100 using any humidity and temperature measurement instrument with a display. Typically field checking is done with a recently calibrated portable instrument.

1. Place the probe of the reference instrument (or the entire instrument) in the same environment as the probe of the RFL100. The environment should be as stable as possible.
2. Wait for 30 minutes for humidity and temperature to stabilize. Verify that measurements are no longer changing at the end of the stabilization period.
3. Record the readings from both instruments.
