1 Introduction Model 3000TA-XL-EU

•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 0-10,000 ppm and then switches to a continuous percent readout from 1-25%. 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
