1-41 Introduction Model Ultra Trace 3000
Teledyne Analytical Instruments
•Alarms Set the alarm setpoints and attributes.
•Range Set up the 3 user definable ranges for the instrument.
Data Entry Keys: Six touch-sensitive membrane switches are used to
input data to the instrument via the alphanumeric VFD display:
•Left & Right Arrows Select between functions currently
displayed on the VFD screen.
•Up & Down Arrows Increment or decrement values of
functions currently displayed.
•Enter Moves VFD display on to the next screen in a series. If
none remains, returns to the
Analyze
screen.
•Escape Moves VFD display back to the previous screen in a
series. If none remains, returns to the
Analyze
screen.
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 ppb and then
switches to a continuous ppm readout from 0-9999.9 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.
NeedleValve: To adjust flow of gas sample
Flowmeter: Monitors the flow of gas past the sensor. Readout is 0.2 to
2.4 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
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
