Digital Meter Display: The meter display is a LED device that

produces large, bright, 7-segment numbers that are legible in any lighting
environment. It produces a continuous readout from 0-100 %. It is accurate
across all ranges without the discontinuity of analog range switching.

Alphanumeric Interface Screen: The VFD screen is an easy-to-use

interface from operator to analyzer. It displays values, options, and
messages that give the operator immediate feedback.

Flowmeter: Monitors the flow of gas past the sensor. Readout is 0.2

to 2.4 standard liters per minute (SLPM).

Standby Button: The Standby turns off the display and outputs,

but circuitry is still operating.

CAUTION: The power cable must be unplugged to fully

disconnect power from the instrument. When
chassis is exposed or when access door is open
and power cable is connected, use extra care to
avoid contact with live electrical circuits.

Access Door: To provide access to the Micro-Fuel Cell and the front

panel electronics, the front panel swings open when the latch in the upper
right corner of the panel is pressed all the way in with a narrow gauge tool.
