The Chadwick Helmuth Model 9600 Accutach Reader measures the frequency of most tachometer generator or magnetic pickup signals, giving exact RPM Measurements for each assembly.
This kit is for the C-130 aircraft and can be used on the P-3, E-2C and C-2A as well.
Complete kit with cables and padded carry case.
Measures & displays tachometer output frequency in Hz, RPM or %RPM
The Accutach is a versatile hand-held, battery operated instrument that can be used in a wide variety of aircraft measurement and calibration applications.
The following examples show its versatility:
- Measure the rotation of a turbine rated at 12,000 RPM at 100% that drives a 70Hz tach generator at 100%.
- Measure the speed of a rotor system rated at 450 RPM at 100% using a magnetic pickup with three single interrupters and one double interrupter.
- Measure propeller RPM using the 1-per-rev pulse from a synchrophasor.
The Model 9600 features a microprocessor that measures input signal period, computes the frequency, controls the display, monitors the keyboard, and stores settings. The keyboard consists of a power ON key, RESET key, display LIGHT key, display CONTRAST control, and four MODE keys for data entry and access to the software menu.
A CHANNEL knob is provided to select up to four input signals from connector J1 or a single input signal from connector J2.
