15.4.1 VOC Zero Calibration Procedure For Enhanced Linearity With Extended-
Range And ppb PID Sensors
You will need a VOC Zeroing Tube Adapter (P/N: 025-3002-000) and a VOC Zeroing Tube (P/N: 025-
2000-010).
1. Inspect the external filter on the instrument and replace it if it appears to be dirty.
2. Break the two ends of a VOC Zeroing Tube by putting the ends into the small hole near the bottom of
the tube box and snapping them off.
3. Connect the VOC Zero Tube Adapter to the external filter on AreaRAE Pro/Plus, and then insert one
end of the VOC Zeroing Tube into the adapter. The arrow on the tube indicates the correct direction.
4. Run the zeroing calibration procedure for the instrument.
5. After zero calibration, properly dispose of the used VOC zeroing tube (it is designed for single use
only), and remove the VOC Zeroing Adapter.
