Digital Meter Display: The meter display is a LED device that
produces large, bright, 7-segment numbers that are legible in any
lighting. It produces a continuous readout from 0-10,000 ppm and then
switches to a continuous percent readout from 1-25%. It is accurate
across all analysis ranges without the discontinuity inherent in 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 button 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: For access to the Micro-Fuel Cell, 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. Accessing the main circuit board
requires unfastening rear panel screws and sliding the unit out of the
case.
