The King Nutronics Model 3800 is a 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 and in the workshop. The Model 3800 exceeds current U.S. Navy specifications. The Model 3800 is 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.
Model 3800 Tachometer Tester
Description:
Features:
- Calibrates 2 and 4-pole generators, as well as RPM and % indicators.
- Calibrates optical tachometers from 500 to 65,000 ROM with the (optional) optical tachometer kit.
- Calibrates jet engine tachometers as percentage of full scale from 1% to 120%.
