Model 200E Instruction Manual 

Theory of Operation 

queries for operation data about the instrument. During interactive tasks, such as instru-

ment calibration or certain diagnostic procedures, the instrument’s response messages are 
also displayed here. 

Concentration Field: The far right portion of the top line of text displays the concentration of 
the sample gas currently being measured by the analyzer. The number reported here is the 

actual concentration of the sample gas reported in whatever units the user selects 
(Section 6.5.6). This number remains unaffected, regardless of how the ranges of the 
instrument’s analog outputs are configured.  

Key Definition Field: The bottom line of text displays is reserved for defining the test 
function of the row of keys just below the display. These definitions change depending on 

which part of the software menu tree is currently being displayed.  

10.3.7.3. Keypad 

The row of eight keys just below the vacuum florescent display are the main method by 

which the user interacts with the analyzer. These keys are context sensitive and are 
dynamically re-defined as the user moves around in the software menu structure. 

10.3.7.4. Front Panel States LED’s 

There are three status LED’s located in the upper right corner of the M200E’s front panel:

10.3.7.5.   Display / Keyboard Interface Electronics 

The display of the analyzer is a vacuum fluorescence display with two lines of 40 text 
characters each. Information is organized as shown in Figure 3-2. Figure 10-17 shows the 
electronic diagram of the display / keyboard circuitry. 

Through the keyboard/display interface electronics, the M

2

00E Analyzer captures the status 

of the eight front panel keys, alerts the CPU when keys are depressed and manages 

communications between the keyboard, the CPU and the front panel display. Except for the 
keyboard interrupt status bit, all communication between the CPU and the keyboard/display
