Applications requiring very quick weight readings should reduce this setting to its
minimum. If the weight is unstable, increase the averages. The HI 6500 series instrument
does 110 updates per second, which translates to an update approximately every 9
milliseconds. If you average enough weight readings, the weight loss or gain remains
smooth. If you average the weight too much you can cause over filling.
Also see
WAVERSAVER for information on filtering unstable weight readings.
RANGE:1-255 (default 10)
On the
Web page
, select the Filter menu selection and enter the value for the number of
readings to factor into the average. Our example (for illustration only) has set 10 for
Number of Averages. Yours will vary depending on your application.
On the
HI 6500 series instrument display
, select the Filter menu and use the UP or
DOWN button to select the NumAverages menu item. The current value will be displayed,
press the ENTER or the RIGHT button if this value needs to be modified.
WAVERSAVER® Parameter
Typically, mechanical noise (from other machinery in a plant environment) is present in
forces larger than the weight variations you want to detect. WAVERSAVER® reduces the
effects of the vibratory forces that exist in all industrial weight control and measurement
applications so the device can better calculate the actual weight. WAVERSAVER enables
the Weight Processor to distinguish between actual weight data and mechanical noise, both
of which are typically conveyed in the load cell signal. WAVERSAVER can be configured
to ignore noise with frequencies as low as 0.25 Hz. One of three higher additional cut off
frequencies may be selected to provide a faster instrument response time. The function is
user selectable and can be turned off.
RANGE: 0.25 Hz, 0.5 Hz, 1.0 Hz, 3.50 Hz, 7.50 Hz, OFF (default 1.0 Hz)
Chapter 1 describes the benefits of using the WAVERSAVER feature.
