Teledyne M300EM User Manual

11.5.10. FRONT PANEL INTERFACE 

The most commonly used method for communicating with the M300E/EM Analyzer is via the instrument’s front 
panel which includes a set of three status LED’s, a vacuum florescent display and a keyboard with 8 context 
sensitive keys.   

 

11.5.10.1. Analyzer Status LED’s 

Three LED’s are used to inform the user of the instrument’s basic operating status.  They are listed on Table 
11-5 as follows:

11.5.10.2. Keyboard  

A row of eight keys just below the vacuum florescent display (see Figure 11-15) is the main method by which the 
user interacts with the analyzer.  As the software is operated, labels appear on the bottom row of the display 
directly above each active key, defining the function of that key as it is relevant for the operation being 
performed.  Pressing a key causes the associated instruction to be performed by the analyzer.   

Note that the keys do not auto-repeat.  In circumstances where the same key must be activated for two 
consecutive operations, it must be released and re-pressed.
