Turning the Unit On
Press the Down Key for 3 seconds, until the
buzzer beeps and the red LED flashes. After a warm
up and self-test sequence, the unit enters normal
reading mode, showing real time gas concentrations.
Turning the Unit Off
In normal reading mode, press and hold the Down
Key for a 5-second count down, until “Unit Off”is
displayed.
Charging
Always fully charge the battery before use. Plug
the charger to the bottom of NEO. The battery icon
on the LCD shows the charge status. During active
charging, the icon cycles from empty to full.
Charging/Comm Cable
The USB Charging/Communications cable allows
charging the unit on a personal computer. A locally-
purchased cable can work as well for charging, but
mPower’s cable must be used for proper data transfer
when communicating with mPower Suite.
Water-trap Filter
Water-trap filters (P/N: M490-0004-010) are used
to protect the sensor from dust and aerosols in dirty
environments. The filter should be twisted on to the
gas inlet before the instrument is used and
replaced once its surface is dirty.
Testing the Alarms
Important! Test the alarms prior to performing a
bump or span calibration test. If any alarm does not
respond, check the Alarm Settings in Config Mode to
make sure all alarms are enabled (Config Mode →
Alm Setting →Alarm Settings →Both Enabled). If
any alarms are enabled but are not functional, do not
use the instrument.
Under normal operation mode and non-alarm
conditions, the buzzer, LED and backlight can be
tested anytime by pressing the Right Key once.
Normal Mode
After warm-up is complete, the unit enters normal
reading mode and displays the instantaneous gas
concentration continuously.
Other values like STEL, TWA, and temperature,
etc. can be checked by pressing the Up/Down Key to
cycle through these screens one by one.
Configuration Mode
In Config Mode, the user can perform a sensor
calibration, change the alarm limits and set up other
parameters.
