The RH60-A RPM / ENGINE HOURS / ELAPSED TIME GAUGE, is a four digit digital display of engine RPM's, total engine hours, and elapsed time. The RH60-A works with any engine and can be driven from a wide range of Tacho signal frequencies and amplitudes. Front panel calibration is provided for spot-on accuracy to +/- 1 RPM. A separate engine hours countdown alarm can be set to remind you of upcoming oil changes or 100 hour maintenance due. A high RPM alarm can be set, and the RH60-A keeps track of the maximum RPM seen. When activated, the RH60-A built-in 85dB alarm will sound and the display will flash. Five different levels of internal backlighting can be selected from and thirteen levels of display dampening. All calibrations, alarms values and Max RPM are saved to a nonvolatile memory. Terminal "C", can be programmed as an External Alarm output if so desired.
