Honeywell AreaRAE Plus - Span Calibration; Three-Point Calibration for Enhanced Linearity with Extended-Range and Ppb PID Sensors

Note: You can abort the calibration at any time during the countdown by pressing [N/-].
Span Calibration
This procedure determines the second point of the sensor calibration.
Note: When a manual calibration is performed, the readings shown are in the equivalent units of
the calibration gas, and not the measurement gas.
Three-Point Calibration for Enhanced Linearity with Extended-
Range and ppb PID Sensors
For better linearity at higher concentrations when an AreaRAE Plus/Pro is equipped with a PID
sensor, a 3-point calibration can be performed.
IMPORTANT!
Three-point calibration is disabled by default, but can be enabled using Safety Suite Device
Configurator (SSDC) Data Management software on AreaRAE Plus/Pro instruments with 10.6eV
PID sensors, including high-range ppm and ppb PID sensors.
Default calibration gas settings for AreaRAE Plus/Pro PID sensors are as follows:
