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.
Flowmeter: Monitors the flow of gas past the sensor. Readout is 0.1 to
2.0 standard liters per minute (SLPM) of nitrogen
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.
