Meggitt's REF2500 handheld shaker checks operation and set-up of accelerometers and velocity sensors in the field. Check acceleration and velocity measurements with no imperial-metric conversions - no extra steps and no calculations. Frequency and measurement type (peak or RMS) can be selected at the push of a button.
- 61.4 Hz for imperial measurements: 1 g (acceleration) equivalent to 1 in/sec (velocity)
- 100 Hz to simulate standard calibration conditions
- 159.2 Hz for metric measurements: 9.81 m/sec2 (acceleration) equivalent to 9.81 mm/sec (velocity)
LED indicators activate if battery levels are low or if the unit is overloaded. A built-in reference accelerometer maintains a 1 g test level for sensors weighing up to 250 grams.
