5 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
stability.
6 SET POINTS
6.1 General Information
Set points are useful for tolerance checking (pass/fail), triggering an external device such as a motorized
test stand, or alarm indication in process control applications. Two limits, high and low, are specified and
stored in the non-volatile memory of the instrument and the primary reading is compared to these limits.
The results of the comparisons are indicated through the three outputs provided on the 15-pin connector,
thus providing “under”, “in range”, and “over” signaling. These outputs can be connected to indicators,
buzzers, or relays as required for the application.
6.2 Configuration
To configure set points, select
Set Points
from the menu. The screen appears as follows:
Either one, two, or none of the set points may be enabled. To toggle between the tension and
compression (or clockwise and counter-clockwise) directions, press the
DIRECTION
key.
