The CGR-30P Premium Engine Monitor’s Main Screen displays the Tachometer and Fuel Flow in large analog arcs at the top of the instrument, providing immediate and quick reference values. The digital display provides accuracy in monitoring engine functions. The CGR Main Screen also features a complete, primary replacement EGT/CHT Bar Graph Engine Analyzer. Each cylinder is monitored by the CGR. If any EGT or CHT temperature rises above or below-programmed limits, the CGR provides an immediate alert. The EGT/CHT Bar Graph Analyzer features both Lean-of-Peak and Rich-of-Peak Modes for easy engine leaning. The CGR-30P will let you know as each cylinder peaks, at what temperature each cylinder peaks, and how far below Peak Temperature each cylinder is operating. To the right of the EGT/CHT Bar Graph Analyzer, the CGR-30P can display three more primary functions to monitor.

The CGR-30P Engine Monitor features a state-of-the-art, full-color bar graph to assist with ROP/LOP leaning. Additionally, the bar graph provides both “normalized” and digital readout screens. No other bar graph in the industry comes close to providing the number of options the CGR-30P offers.

Monitor: Lean-of-Peak Mode

For Lean-of-Peak Operations, the CGR-30P Premium Engine Monitor informs the pilot as each cylinder peaks, at what temp each cylinder peaks, and how far from peak temp each cylinder is. For quick reference, every cylinder’s peak information is constantly displayed and “tattletale bars” are shown above each cylinder, indicating where each cylinder peaked.

Fuel Flow is displayed during the entire leaning process to assist in finding the optimal fuel-to-air mixture.

Monitor: Rich-of-Peak Mode

The number of degrees below Peak EGT is displayed on the first cylinder to Peak. Fuel Flow is displayed during the entire leaning process to assist in finding the optimal fuel-to-air mixture.

The Secondary Screen, on the CGR-30P Premium Engine Monitor, is intended to display functions which do not need to be displayed continuously. This Screen will display a red (warning) and/or yellow (caution) numerical value for a Primary Function of your choice. This function will also annunciate between the arcs on whichever Screen you’re viewing if a limit is violated. The red and/or yellow range annunciators directly under the arcs on the Secondary Screen will blink to alert the pilot of any potential problem with a primary function on the Main Screen.
