The Ultimate Bar Graph is capable of monitoring up to sixteen channels, including many different functions, such as RPM, Manifold Pressure, Volts/Amps, Gyro Vacuum Pressure, Fuel Pressure and Oil Pressure.
These non-temperature functions are monitored by using Electronics International's Function Modules. The flexibility of the modules allow you to customize your instrument to include the features you most need and want, without having to pay for extras that you may not find useful.
All of the functions on the UBG-16 can be programmed to alert pilots of high and low limits, so you don't have to constantly watch these monitored functions; the UBG-16 will do it for you and will alert you immediately if anything is amiss.
The FM-RPM allows pilots to keep a close watch on their RPM through their UBG-16. The FM-RPM-X package includes the module, two Magneto Signal Isolators, two Signal Pickup Leads, a Wire Harness and Instructions.
