TOOLS key and then use the

In the process of calculating the sum quantities (the data that
appears under the
∑
menu) the HVM100 multiplies the
instantaneous acceleration for each channel by a scaler fac-
tor (sometimes called a k-factor). The HVM100 allows the
user to select a different k factor for each channel. The
default setting is 1.00; however; some applications may
require different settings.
NOTE: To change the Sum Factor
parameter, press the
c
key, use the
u
and
d
arrows to select the desired
value, and then use the
r
and
l
arrows to move to the next position.
Once all positions are set press the
c
key or move to any other part of the
HVM100 to accept the entry.
The applications that require the Sum Factor to be altered
are specified in certain ISO standards. If you are not trying
to measure according to any specific standard, the appropri-
ate setting for this parameter is 1.00.
AC/DC Output
Hint:
This setting is in the Tools menu. To access the Tools menu press the
TOOLS

u
and
d

through the menu items.
