Digital Meter Display: The meter display is a Light Emitting Diode
(LED) device that produces large, bright, 7-segment numbers that are
legible in any lighting. It produces a continuous readout from 0-999.9
ppb and then switches to a continuous ppm readout from 0-100.00 ppm.
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 0.1 to
2.0 standard liters per minute (SLPM) of nitrogen
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
