Inserting Sensors
Important! Always make sure your hands are clean and dry before handling sensors.
Place a sensor into a socket, aligning it with the matching keyways and the multi-pin connector at the bottom. Once a
sensor is plugged in, its corresponding green LED flashes once and if it requires warm-up, then warm-up begins. Below
are approximate times for sensor warm-up.
Non-EC sensor: 0 hours (no warm-up required)
Non-biased EC sensor: 6 hours
Biased EC sensor: 24 hours
If the green LED does not blink, the sensor is not inserted properly.
Note: If the sensor is properly seated and you remove it at any time during its warm-up, it must be returned to its socket
within 20 seconds, or the SensorRAE 4R+ will restart the warm-up cycle from the beginning.

Removing Sensors
Always lift sensors out with your fingers, gripping around the sides.
Checking Sensor Status
You can check the status of a sensor being warmed up by pressing the power button. If the green LED next to the
sensor glows, it is fully conditioned and ready for use.
