If the VMID point ID has been saved but not the K(t) start values, then this is the
next step. By pressing the ▼ key the currently measured RMS RMS(t) and peak
value Peak(t) are saved as K(t) the start value RMS(0) and Peak(0) (Figure 28).
When the sensor is newly placed on the VMID measuring point, the instrument au-
tomatically switches to the K(t) display. It then reads the start values from the mem-
ory and calculates the K(t) value from the currently measured RMS(t) and Peak(t)
values (Figure 29).
Press the ▼ key to save the K(t) values. Press F1 to view the graphic trend display.
(cf. Section 7.5)
Note: If the instrument displays OVERLOAD, it is not necessarily the result of a too
high acceleration value. It can also be due to a base value of zero, which causes a di-
vision through zero.
