STATUS LEDs

 

Active Green 

OFF 

Unit is operating in 

STANDBY mode. 

This LED glows green when the instrument is actively 
producing calibration gas.

 

Auto Yellow  OFF 

This LED only glows when the calibrator is performing an automatic 
calibration sequence. 

Fault Red BLINKING 

The calibrator is warming up and therefore many of its subsystems 
are not yet operating within their optimum ranges.  Various warning 
messages will appear. 

 

A row of eight keys just below the vacuum florescent display (see Figure 9-10) is the main method by which the 
user interacts with the calibrator.  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 calibrator.   

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.   

The main display of the calibrator is a vacuum florescent display with two lines of 40 text characters each.  
Information is organized in the following manner (see Figure 9-10): 

  MODE FIELD: Displays the name of the calibrator’s current operating mode. 
  MESSAGE FIELD: Displays a variety of informational messages such as warning messages, operation 

data and response messages during interactive tasks. 

  KEY DEFINITION FIELD: Displays the definitions for the row of keys just below the display.  These 

definitions dynamic, context sensitive and software driven.
