The R200/R250 Replaceable Sensor was carefully tested and calibrated before being
shipped from the factory. For greatest accuracy, we recommend replacing the sensor
every 6-12 months (does not include N400 and N450).
When your new Replaceable Sensor arrives, simply turn off the recorder, remove and
discard the old sensor, plug in the new one and power the recorder back on. Your
recorder will continue to record temperature and humidity without interruption.

If you have an accurate standard to compare against, the Replaceable Sensor calibration can be
adjusted at one point. This will not adjust the span and is not as accurate as replacing the
Replaceable Sensor with a newly calibrated one.
