Electronics International CGR-30P - Manual (Page 16)

2.3 RPM and Manifold Pressure:
The RPM and M.P. instruments incorporate a digital readout and an
analog arc. The color of the digital readout will reflect the current range
in which the function is operating (i.e., if the RPM is operating in the red,
the digital readout will be displayed in red).
The digital display will blink when the RPM or M.P. operating level
reaches a yellow or red operating range. To stop the blinking, push the
Exit button. Also (if so equipped), acknowledging a voice warning using
the external “Voice Alarm Control Panel” will stop the blinking of any
digital display.
The CGR’s RPM Instrument provides a Mag Out feature in addition to
the arc and digital display. The CGR continually monitors both mag
signals. If one mag fails or is turned off, an appropriate “Mag Out”
warning will be displayed on the appropriate side of the RPM digital display.
2.4 Horizontal Strip Gauges:
The three Horizontal Strip gauges provide the following features:
A. The colored operating ranges shown on the Horizontal Strip can be set up for any aircraft.
B. Each Horizontal Strip Gauge features a pointer (triangle) marking the current operating level. Also, the
pointer allows the pilot to interpret rate and trend information and provides field of vision.
C. A digital display is provided with each Horizontal Strip Gauge.
D. The digits on the digital display will blink when a function’s operating level reaches a yellow or red
operating range. To stop the blinking, push the Exit button. Also (if so equipped), acknowledging a voice
warning using the external “Voice Alarm Control Panel” will stop the blinking of any digital display.
2.5 Bar Graph Analyzer:
The Bar Graph Analyzer has six operating modes: EGT/CHT, Normalized, Lean ROP, Lean LOP, EGT and
CHT. The CGR’s current mode of operation is displayed in the top left portion of the Bar Graph Display. The
SELECT knob may be used to change operating modes.
2.5.1 “EGT/CHT” Operating Mode: The vertical bars are arranged to show the EGT and CHT for
each cylinder. The operating ranges for the EGT bars may be set to match your engine’s operating
temperatures (i.e.; if your full rich low power EGT readings are around 1100’F, set your Low EGT Range
for 1000’F. If your peak EGT readings are around 1500’F, set your High EGT Range for 1525’F). The
high and low EGT ranges may be set in the “EGT/CHT Bar Graph Setup” screen (see section 6).
