2. Measurement in Vibration Meter Mode
①
Selecting the analysis function to “Vibration meter mode” after common setups.
Press the VM/TIME/FFT key to select the Vibration meter mode. The analysis function can be selected to each
mode as shown in the following figure by pressing the VM/TIME/FFT key.
The five kinds of vibration values are measured and displayed simultaneously and updated in one second
intervals. The bar graph indicates a selected data by the ACC/VEL/DIAP key. Acceleration, Velocity, and
Displacement are selectable.
②
Input range setting
Set the input range to the optimal setting. The optimal setting is to use the lowest range where an overload
does not occur. The key changes to the higher range, the key changes to the lower range.
By changing input range, an electric transient noise occurs and overload may be displayed.
In t
his case, it is
not an excessive input of vibration. When an overload is displayed immediately after changing input range,
please wait for a while. The overload may disappear.
