Model 3800 Tachometer Tester
Description:
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.
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%.
- Calibrates electrical and cable-driven tachometers.
- Accurate to within ±0.02% of set point value.
- Normal operating range from 1 to 6,500 RPM.
- Intuitive front panel controls for efficient testing.
- Manual Adjust mode for easy tachometer troubleshooting.
- Standard AND 20005 drive pad.
- Internal Wye-connected and delta-connected load banks.
- Quiet operation.
- Stores up to 4 user-programmable test scenarios for both Tacho-Gen and Tacho-Indicator (in addition to the standard scenario).
Specifications:
- Accuracy: ±0.02% of the set point value in all operating modes
- Resolution: 1% or 1 RPM (10 RPM in 10:1 multiplier mode)
- Setpoint stability: ±0.01% IV throughout operating range
- Operating Range:
RPM mode: 1 to 6,500 RPM in 1 RPM increments
% (Percent) mode: 1 to 120% in 1% increments
Optical mode: 500 to 65,000 RPM in 10 RPM increments - Display Units: RPM or %
- Tachometer Drive Pad Type: Standard ¼” square female coupling in accordance with AND 20005, Type XV-B
- Input Power:
Voltage: 120 (or 220) ±10% VAC, 50 to 60 Hz
Current (max.): 4 Amps
Fuse type (2 required): 1 Amp and 5 Amps - Case Dimensions & Weight:
13.25”L x 9.2”W x 11.5”H
19 lbs. (8.62 kg.)
