7 DIGITAL FILTERS
Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.
To access digital filter settings, select
Filters
from the menu. The display appears as follows:
Two filters are available:
Current Reading
– Applies to the peak capture rate of the instrument.
Displayed Reading
– Applies to the primary reading on the display.
Available settings:
1,2,4,8,16,32,64,128,256,512,1024.
It is recommended to keep the current reading
filter at its lowest value for best performance, and the displayed reading filter at its highest value for best
visual stability.

8.1 Initial Physical Setup
The dynamometer should be mounted vertically to a test stand or fixture rugged enough to withstand a

used, along with appropriate mounting brackets and fixtures. Caution should be taken while handling
such equipment.
