Diesel Engine Tachometer
GE-1400
Both analog (switchable between analog and monitor output) and pulse outputs are provided; enabling to use analog output for data recording (monitor output for sensor waveform checking or analysis input signal of FFT analyzer), and to use pulse output for tracking analysis signal of FFT analyzer.
The GE-1400 may not be able to measure depending on the engine type. For engines that have not been measured before, please confirm with a demo machine. For demo machines, please contact your nearest distributors or sales office nearby.
Features
Built-in memory function
20 data (MAX) can be saved to memory.
Three outputs (analog, monitor and pulse) provided as standard
Use the analog output function to record the number of rotations, the monitor output function to check the sensors detection waveform, and the pulse output function to output rotation synchronization signals.
Large LCD with backlight
(Character height: 10.2 mm)
Trigger adjustment function provided
Can be mounted on a tripod
The tachometer can be fixed to a tripod for continuous measurement.
