Calibrate and Select Gas
WARNINGS
The calibration of all newly purchased RAE Systems
instruments should be tested by exposing the sensor(s) to
known concentration calibration gas before the instrument
is put into service for the first time.
For maximum safety, the accuracy of the MiniRAE 2000
should be checked by exposing it to known concentration
calibration gas before each day’s use.
In the first menu of the programming mode, the user can
perform functions such as calibration of the MiniRAE 2000
Monitor, select default cal memories, and modify cal memories
(see Table 4.4).

Calibrating the MiniRAE 2000 monitor is a two-point process
using “fresh air “ and the standard reference gas (also known as
span gas). First a “Fresh air” calibration, which contains no
detectable VOC (0.0 ppm), is used to set the zero point for the
sensor. Then a standard reference gas that contains a known
concentration of a given gas is used to set the second point of
reference.
