Display Parameters
All display modes of operation have the following Acceleration display
parameters which are identified as Acceleration with a preceding ‘A’: -
Aeq
The Aeq is time averaged and weighted with a frequency filter that is either
set automatically or selected by the user depending on the mode of
operation.
Arms
The Arms is the weighted, running RMS (Root Mean Square) acceleration
value.
Amax
The Amax is the maximum Arms level reached.
Pmax
Pmax is the highest peak level of the weighted instantaneous acceleration.
Scrolling between these four parameter screens is achieved using the
Left
and
Right Arrow
Keys
.
The dominant axis is always identified by having the
>
character displayed next to
it.
In Single Axis mode or Cusotm mode either a single integration change from
Acceleration to Velocity or a double integration change from Acceleration to
Displacement is possible. Depending on the integral method chosen, the
selectable display parameters are shown below: -
Velocity
Veq Vmax Vrms Pmax
Displacement
Deq Dmax Drms Pmax
