Three-Point Calibration For Enhanced Linearity With Extended-Range And Ppb Pid Sensors - Honeywell MultiRAE Series User Manual

Three-Point Calibration for Enhanced Linearity with Extended-
Range And ppb PID Sensors
For better linearity at higher concentrations when a MultiRAE is equipped with a PID sensor, a
3-point calibration can be performed.
It is recommended to use a 3-point calibration using a high-range PID sensor in a multi-gas
monitor when a specific gas of interest concentration is required. For more information review

IMPORTANT!
Three-point calibration is disabled by default, but can be enabled using Safety Suite Device
Configurator (SSDC) software on MultiRAE and MultiRAE Pro instruments with 10.6eV PID
sensors, including high-range ppm and ppb PID sensors. The MultiRAE Lite PID sensor does
not support three-point calibration.
Default calibration gas settings for MultiRAE PID sensors are as follows:
