D. AQ EXPERT STARTING INSTRUCTIONS
1. Make sure the instrument is in a clean-air, room-temperature environment and
turn it on by pressing the
POWER
key on the keypad. The instrument will begin
to draw in air from the SAMPLE IN inlet at a rate of about 500 cc/minute.
2. If needed or in doubt of the contaminants in the Ambient Air, you can initiate the
ZERO CAL on ALL of the GAS sensors on the AQ Expert. Please refer to
CHAPTER 8 of this manual for ZERO & SPAN calibration on the AQ Expert.
3. Press the
MEASURE
key to view the ambient temperature, barometric pressure,
relative humidity and dew point. The toxic gas readings are also displayed: CO,
CO2, NO, NO2, SO2, H2S, O3, & VOCs.
4. If, at the end of the ZERO countdown, if the display shows an error message for
a particular sensor, see the troubleshooting table in section D of this chapter. The
instrument will measure correctly all sensors that do not show an error message.
