1. Multi-Function Capability:
The Ultimate Analyzer has up to 16-channel capability, 8 for each of the displays. For a 6-cylinder single
engine aircraft, the first 6 channels on the left display should be used for EGT and the first 6 channels on the
right display should be used for CHT. For a twin-engine aircraft the first 6 channels should be left EGT and
right EGT. These channels are designated as analyzer channels. The Peak Locate, Hottest Cylinder Indica-
tor and Differential Warning features are only functional on the analyzer channels. The number of analyzer
channels is independently programmable from 1 to 8 for each display. The High-Temp and Low-Temp
features are functional on all channels and may be used to measure any temperature (TIT, Oil, EGT, CHT,
OAT, Carb, Induction Air, Cabin Air, Cowling Air, Intercooler, Water, etc.).
2. Mode Select Switch:
A) Manual Mode - With the Mode Select Switch in the center position, the Ultimate Analyzer will display
the temperatures on the channel designated by the green Channel Indicators. No other channels are being
monitored at this time. In the Manual Mode the Shock-Cooling and High-Temp warning features are enabled
for only the channel displayed. The Low-Temp and Differential warning features are disabled so you may
operate the aircraft at idle and taxi without getting warning lights.
B) Step Position - Each time the Mode Select Switch is pressed to the right, the Ultimate Analyzer will
advance to the next channel. When this switch is released, it will return to the center position (Manual
Mode). The Ultimate Analyzer can be programmed from the front panel to step through 2 to 8 channels.
C) Scan Mode - In the Scan Mode, the Ultimate Analyzer will scan through the channels, automatically
analyzing your engine. When the unit is first placed into the Scan Mode, it will switch to Channel One to
start its scan. This is done to establish a reference for the automatic engine analysis features.
In the Scan Mode the High-Limits, Low-Limits, and Differential warning features are enabled. The Shock-
Cooling feature is disabled (Shock-Cooling is only a problem during descents).
The Ultimate Analyzer may be placed in the Scan Mode during run up, takeoff, climb or cruise, as long as
the engine temperatures are increasing or stable and above the programmed lower limits. This unique
operating characteristic allows the Ultimate Analyzer to stand watch over your engine during most phases of
a flight. But if the engine temperatures are decreasing (which would occur on a descent) or low (which
would occur at idle, the Ultimate Analyzer should be placed into the Manual Mode of operation to eliminate
any false Low or Differential Condition problems it may find and to enable the automatic Shock-Cooling
detection feature.
3. Peak Locate Switch:
There are two Peak Locate Switches, one for the left display and one for the right. The Peak Locate feature
may be used in the Manual or Scan Mode of operation. Its purpose is to eliminate all of the mental calcula-
