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 125 %. 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).
