The 4501 has been designed to detect loose particles in electronic components - programmable to provide speedy and precise automatic testing in accordance with MIL-STD-883C Method 2020 for hybrids and MIL-STD 750C Method 2052.

• A flexible microprocessor-based controller with simple keyboard entry of all test parameters
• A specially designed shaker to shock and vibrate the device under test
• An oscilloscope for visual monitoring of signals created by loose particle impacts
• A speaker for audio monitoring of signals created by loose particle impacts
• Intensified oscilloscope display during threshold detector output
• An indicator lamp that lights each time a particle impact is detected
• An indicator lamp that lights and remains lit after a particle impact signal exceeds the failure threshold level
• Numerical  display of measured shock and vibration amplitudes
• Numerical display of programmed frequency and other test parameters
• Automatic frequency calculation from test package cavity height per MIL-STD 883C Method 2020 requirements
• Abort function will stop the test on the first detection  of a particle impact
• Keyboard lock with a fixed, code number program entry key prevents inadvertent alteration of the test program
• Test sequence program maintained in memory by battery power during primary power failure or equipment power off
• Overriding manual operation when desired
• Super low noise level for detecting micro-particles
• Simplified Sensitivity Test Unit (STU) checkout method that meets MIL-STD 883C Method 2020 and MIL-STD 750C Method 2052
