Description
The HVM100 is a hand-held instrument for measuring human exposure to vibration, performing the relevant calculations and providing overall results on the LCD display. The results may also be stored in the built-in data logger which can hold up to 100 separate time histories and be down loaded to a PC for further analysis and archiving
 
Measuring all three axis simultaneously simplifies the test setup, testing time and enhances the repeatability and correlation of the measurements. Both Peak and RMS levels of the 3-axis may be stored together with the important vector sum which the HVM100 also calculates.
 
The results, current and recalled from the memory may be downloaded to a PC - order the  HVM SW  utility software, if required. Alternatively Hyper-Terminal an 'Accessories' program in Windows will download HVM100 files one at a time.
 
The analyser provides AC and DC outputs for connecting to FFT analysers like the B&K 2250 for immediate detailed analysis or recording the 'raw data' for archiving or subsequent post processing.
