It is suitable for monitoring all kinds of vibrating mechanical facility, specially the vibration measurement of rotating and reciprocating machinery. The unit can measure acceleration, velocity and displacement, which is widely used in mechanical manufacture, electric power metallurgy and general aviation, etc.Features:1. Visually displays measurement value and state.2. Support acceleration, velocity and displacement measurement.3. Different vibration frequency selection.4. High sensitivity probe for accurate measurement. Provides long and short probe head, each one is suitable for different situation measurement.5. Equipped with AC signal output interface.6. Support low power indication function and auto power-off function.7. Simple to use, the structure is compact, portable for carrying along with measurement.Note:1. Using short probe (S) can take measurement of vibration both in high (HI) and low (LO) frequency.2. Long probe (L) is only suitable for low frequency measurement. When taking velocity measurement, also the frequency is over 1KHz, please replace with the short probe.3. When switching acceleration (HI high frequency) measurement mode to velocity or displacement mode, the high frequency (HI) will be changed to low frequency (LO) automatically. 4. High / low frequency selection is only available in acceleration measurement.5. Due to manual measurement, the size may be slightly different. Thank you for your understanding.6. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.Specifications:Brand: SMART SENSORModel: AS63AColor: GreyShell Material: ABSVibration Pickup: Piezoelectric ceramic accelerometer ( shear-type )Measurement Range Of Acceleration: 0.1-199.9m/s² peakMeasurement Range Of Velocity: 0.1-199.9mm/s rmsMeasurement Range Of Displacement: 0.001-1.999mm p-p ( Velocity and displacement range is limited by acceleration 199.9m/s² )Measurement Accuracy: ±10% + 2 digitsMeasurement Frequency Range Of Acceleration: 10Hz-1KHz (LO), 1KHz-15KHz (HI)Measurement Frequency Range Of Velocity: 10Hz-1KHz (LO)Measurement Frequency Range Of Displacement: 10Hz-1KHz (LO)Displays Update Cycle: 1 secondsLCD Display: 3 1/2 digits displaySingle Output: AC output 2V peak (display full scale), load impedance 10KΩ or more earphones can be connectedPower Supply: 1.5V AAA battery ( not included )Static Current: ≤20uAOperating Current: ≤25mAAuto Power-off Function: Turns off automatically after 60 secondsLCD Backlight Function: 7 secondsOperating Temperature Range: 0~40℃Operating Humidity Range: 30~90% RHLow Battery Indication: 2.2V ± 0.2VStorage Case Size: 23.5*18*5cm / 9.25*7.09*1.97in Vibration Meter Size ( with Short Probe ): 6.7*3*18.3cm / 2.64*1.18*7.20in Vibration Meter Weight: 147g / 5.19ozPacking Size: 25.5*21*5.8cm / 10.03*8.27*2.28inGross Weight: 610g / 21.52ozPackage List:1 * Vibration Meter ( without battery )1 * Long Probe1 * Short Probe ( Equipped on the main unit )1 * Storage Case1 * User' s Manual ( English )Package List:1 * Vibration Meter ( without battery )1 * Long Probe1 * Short Probe ( Equipped on the main unit )1 * Storage Case1 * User' s Manual ( English )
