9600 Accutach
 |
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. |
