3 Operation
The calibration of all newly purchased RAE Systems instruments
should be tested by exposing the sensor to a known concentration
calibration gas before the instrument is used or put into service. Prior
to factory shipment, the RAEGuard 2 PID is calibrated and tested.
However, the user should calibrate the instrument before the first use.
Kit Accessories include: RAEGuard 2 Magnet Key, and User’s
