Instrument Basic Functions
The NEO gives real-time measurements or single-point benzene measurements and activates alarm
signals whenever the reading 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, the instrument should be tested and the calibration verified before the first use. After the
instrument is fully charged and calibrated, it is ready for immediate operation.
Turning The Instrument On
Press and hold the Mode (Down) key
until the display, beep buzzer & LEDs turn on.
If the mPower logo does not appear first, there is likely a problem and a distributor or mPower
Technical Support should be contacted. The instrument then performs self-tests after the screen
displays the firmware version and serial number.
Self-tests include:
After self-tests, the instrument will show sensor information and instrument configuration
information in sequence. Once the startup procedure is complete, and a numerical reading screen
with icons is displayed, the instrument is fully functional and ready for use.
Turning the Instrument Off
Press and hold the Down key
for 3 seconds, and continue to hold for a 5-second countdown
until “Unit off...” is displayed.
Integrated Sampling Pump
The instrument includes an integrated, diaphragm-type sampling pump that can operate at low or
high speed, ranging from about 300 to 430 cc/min, respectively, with no filters, 260 to 390 cc/min
with a standard 0.45 µm filter in place, and about 240 to 350 cc/min with both a benzene tube and
0.45 µm filter. Flow will decrease if the 0.45 µm filter accumulates particulate matter, or if a filter is
not used and particles get caught in the pump diaphragm. Connecting Teflon tubing with 1/8" inside
diameter to the gas inlet port, this pump can pull air samples from 200' (61 m) away horizontally, or
