Product Overview
Main Screen

The CGR-30C provides several full-color strip gauges and/or arc gauges (see the alternative configuration below). These give pilots a quick reference view of critical parameters, along with digital readouts for the pinpoint accuracy expected from Electronics International products.
Main Screen Alternative Configuration

The CGR-30C offers an alternative Main Screen configuration with MP and RPM arcs.
CGR-30C Secondary Screen

The Secondary Screen is intended to display functions which do not need to be displayed continuously. This screen can display up to 6 secondary functions or additional primary functions that will not fit on the Main Screen. These primary functions will all annunciate to whichever screen you’re viewing if a limit is violated. The red and/or yellow range annunciators on the Secondary Screen will blink to alert the pilot of any potential problem with a primary function on the Main Screen.
Checklists Feature
Valuable Tool for Safe Flights
- Checklists can help ensure critical steps are followed in any phase of flight.
- Store up to 50+ custom checklists.
- Checklists can be created in a text editor, then uploaded via USB to the CGR-30C.

CGR-30C Data Recording
Data Recording
This CGR-30C Cluster Gauge Replacement screen allows you to download Flight Data to a USB flash drive and set the Data Sample Rate. The Data Sample Rate is the time interval between recorded data. The CGR-30C can record up to 1500 flights before it records over the oldest flight first.
The USB port may be found mounted in the instrument panel or hanging under it. Flight Data is recorded and downloaded in a comma-delimited format. This allows the file to be ported directly into Excel.
