1 Introduction
1.5.1 Displays
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 0-9999 ppm and from 1-
25 %. It is accurate across all ranges without the discontinuity of analog
range switching.
Alphanumeric Interface Screen: The backlit 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).
