Operating Information
NOTE: The Ultimate Analyzer will stop on the first channel on which it finds a problem and light the
appropriate “Temp Prob” warning light. If the problem corrects itself, the “Temp Prob” warning light will go
out and the Ultimate Analyzer will continue its scan.
6. Back Light and Green Channel Indicator Intensity:
The Ultimate Analyzer comes with 12 and 24 volt digital display back light control lines. The digital display
should be backlit all the time. This will allow it to be easily viewed in dim light. The digital display is best
viewed in high ambient light or direct sunlight.
Also provided is a Green Channel Indicator Intensity Control Line. If this line is connected to your Panel
Light Rheostat, the Green Channel Indicators’ intensity can be controlled for night operation. As the Panel
Light Rheostat is turned up the Green Channel Indicators will dim. If you find the Green Channel Indicators
to be too bright during daytime operation, turn the Panel Light Rheostat up slightly to control the intensity of
the Green Channel Indicators to suit your requirements.
Programming
Although programming may be new to some of you, programming the Ultimate Analyzer is simple. After a
few tries, you should have the hang of it. No matter which buttons you push or limits you set you cannot hurt
the Ultimate Analyzer and any limit can be reset.
Your objective is to set the limits on the Ultimate Analyzer just outside the normal operating temperatures for
each measured parameter (see “Selecting the Proper Limits” section of this manual). The 36 programmable
limits allow you to characterize the Ultimate Analyzer to your engine. That means trend analysis and prob-
lem detection is done automatically every 16 seconds and you are alerted as soon as a problem starts to occur
(i.e., if an engine temperature starts to drift high or low from its normal operating temperature range it will be
detected by a High, Low or Differential limit). This is a far better method of trend analysis than pouring over
pages of data every six months.
The golden rule for setting the limits on the Ultimate Analyzer is “No Red Light During Take-Off, Climb or
Cruise.” The following sections will describe how to program the Ultimate Analyzer.
1. Manual Programming Mode:
There are two programming modes: Manual and Scan. In the Manual Mode you can program the High
Limits, Low Limits, Differential Limits and Shock-Cooling Limits for both the left and right displays.
Before setting your limits it may be helpful to read the “Selecting the Proper Limits” section of this manual
to get an idea where the limit should be set.
