Note:
Calibration intervals and bump test procedures may vary due to national
legislation.
13.1. Bump Testing & Calibrating With An AutoRAE 2™
Bump testing and calibrating a ToxiRAE Pro CO
2
can be done with an AutoRAE 2
Automatic Test And Calibration Station. Follow all instructions in the AutoRAE 2 User’s
Guide for successful bump testing or calibration.
13.1.1. Bump (Functional) Testing
With the ToxiRAE Pro CO
2
in Normal Mode:
1.
Connect the calibration gas cylinder, flow regulator, and calibration adapter to the
ToxiRAE Pro CO
2
and start the gas flow.
2.
Make sure the unit goes into alarm and that the buzzer produces at least two beeps per
second, the LED lights flash on and off, and the vibration alarm functions. The
display backlight should illuminate and an alarm message should be shown in the
display.
3.
Turn off the gas flow.
4.
Remove the calibration adapter.
Note:
Bump testing and calibration can also be performed by using the RAE Systems
AutoRAE 2 Automatic Test And Calibration Station. Refer to the AutoRAE 2 User’s
Guide for instructions.
13.2. Calibration Adapter
The ToxiRAE Pro CO
2
is a diffusion monitor and must be calibrated using a fixed-flow
regulator with a flow rate between 0.5 and 1.0 liters per minute. The ToxiRAE Pro CO
2
is supplied with a special calibration adapter that covers the gas inlet. If the local air has
impurities that might interfere with zero (fresh air) calibration, the calibration adapter and
a cylinder of clean zero air should be used.
13.2.1. Connecting The Calibration Adapter
The supplied Calibration Adapter has a removable insert to allow bump testing and
calibration to be performed on the instrument regardless of whether it has a rubber boot
installed. Use the Calibration Adapter without the insert to calibrate the instrument in the
rubber boot, and with the insert to calibrate the instrument without the rubber boot on it.
