Hand-Arm Vibration – Monitoring Operator HAV
Model VC431 Vibrometer (HA Mode) + HA Tri-axial accelerometer by CESVA Instruments
Monitoring Operator HAV
The VC431 triaxial vibrometer (in accordance with the regulation ISO 804) is an ideal instrument for field vibration measurements of hand-arm vibration levels.
The hand-held instrument is ideally suited to the field assessment of hand-arm vibration (HA) due to it’s compact size and low weight, and ease of use.
The vibrometer has great storage capacity and saves the time history of all measurements. The vibrometer has USB connectivity and power.
The VC431 has a user-friendly display which simultaneously measures vibration in three axes and displays all relevant parameters for hand arm vibration exposure assessment.
The functions available for HA measurements are shown in the following table:
|Description of HAND-ARM (HA) Mode functions
|Rms value of acceleration in the x axis with Wh weighting
|Total value of acceleration
|Daily exposure to vibration
|Projected daily exposure to vibration
|Projection time (programmable)
The tri-axial accelerometer (AC031) is fitted to the handle of the work equipment using the optional handle adaptor
The free CESVA Capture Studio software (included with the vibrometer) enables the measurements conducted with the VC431 to be easily downloaded via USB and the results analyzed quickly and simply.
