1 Introduction Model 6000A
Teledyne Analytical Instruments
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 is accurate across all analysis ranges. The 6000A models
produce continuous readout from 0-10,000 ppm and then switch to
continuous percent readout from 1-100 %.
Alphanumeric Interface Screen: The backlit VFD screen is an easy-
to-use interface between operator and analyzer. It displays values, options,
and messages for immediate feedback to the operator.
Power Button: The button switches the instrument power
between
I
(ON) and
O
(a Keep-Alive state). In the
O
state, the instrument’s
circuitry is operating, but there are no displays or outputs.
CAUTION: The power must be disconnected 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 electronics and interface panel, the front
panel swings open when the latch in the panel is pressed all the way in with
a narrow gauge tool. Accessing the main circuit board and other electronics
requires unfastening the rear panel screws and sliding the unit out of the
case.
1.5 Control Unit Interface Panel
The Control Unit interface panel, shown in Figure 1-2, contains the
electrical terminal blocks for external inputs and outputs. The input/output
functions are described briefly here and in detail in the
Installation chapter of
this manual.
