4.4 Calibration of ToxiRAE Unit
CALIBRATION 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 used or put into service.
For maximum safety, the accuracy of the ToxiRAE should
be checked by exposing the sensor(s) to known
concentration calibration gas before each day’s use.
In programming mode, the user may re-calibrate the
ToxiRAE Unit. This is a two-point calibration process
using "zero gas" and the standard reference gas. First, a
"zero gas" which contains no detectable organic gases or
vapors is used to set the zero point. Then a standard
reference gas, which contains a known concentration of a
given gas, is used to set the second point of reference (also
known as span gas). The two-point calibration procedure
is detailed below. Table 4.2 shows the sub-menus for
calibration operations.
