TACHOMETER TESTER
- Compact, lightweight and quiet tachometer tester designed specifically for calibrating and troubleshooting aircraft and helicopter tachometer indicators and generator/alternator systems on the flight line in the workshop.
- Accurate to within ±0.02% of the set point value throughout its operating range of 1 through 6,500 RPM in 1 RPM increments.
- Calibration can be performed in the clockwise or counter-clockwise directions using RPM units, or as a percentage of full scale from 1% to 120% (42 to 5040 RPM) in 1% increments for jet engine tachometers.
