CHAPTER

The instrument is designed as a broadband VOC gas monitor and datalogger for work in
hazardous environments. It gives real-time measurements and activates alarm signals
whenever the exposure exceeds preset limits. Prior to factory shipment, the instrument is preset
with default alarm limits and the sensor is pre-calibrated with standard calibration gas.
However, you should test the instrument and verify the calibration before the first use. After the
instrument is fully charged and calibrated, it is ready for immediate operation.
Turning the instrument on
1. With the instrument turned off, press and hold [MODE].
2. When the display turns on, release the [MODE] key.
Note: The main display may show ppb or ppm and other features, depending on the instrument.
The Honeywell logo should appear first. (If the logo does not appear, there is likely a problem
and you should contact your distributor or Honeywell RAE Systems Technical Support.) The
instrument is now operating and performs self-tests. If any tests (including sensor and memory
tests fail), refer to the Troubleshooting section of this guide.
Once the startup procedure is complete, the instrument shows a numerical reading screen with
icons. This indicates that the instrument is fully functional and ready to use.
Turning the instrument off
1. Press and hold the [MODE] key for 3 seconds. A 5-second countdown to shutoff begins.
2. Once the countdown stops, the instrument is off. Release the [MODE] key.
3. When you see "Unit off..." release your finger from the [MODE] key. The instrument is now
off.
Note: You must hold your finger on the key for the entire shutoff process. If you remove your
finger from the key during the countdown, the shutoff operation is canceled and the instrument
continues normal operation.
