Filter Parameter Menu
There are two parameters in the Filter menu
 NumAverages (Number of Averages)
 WAVERSAVER
NumAverages Parameter
The value you enter for NumAverages (the Number of Averages) sets the number of weight readings used to compute a
sliding average of displayed weight. This helps reduce the effects of material impact and/or vibration if material does not
enter or exit the scale evenly. This setting helps the instrument ignore the effects of material impact and/or vibration.
Applications requiring very quick weight readings should reduce this setting to its minimum. If the weight is unstable,
increase the averages. The HI 6600 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:1-250 (default 10)
On the Web page Or Using the Front Panel Display: enter the value for the number of readings to factor into the
average.
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.
On the Web page Or Using the Front Panel Display: from the pull-down list, select the FILTER menu and
then select the value for WAVERSAVER.; Or select from the list of values supported using the arrow keys.
