PR/SR balances
5 Applications
5.1 Dynamic weighing with statistics – " Dynamic "
In dynamic weighing you obtain stable weighing results even if the weighing sample or the balance itself moves, e.g. in animal
weighing or if the balance is wobbling.
After start of the weighing, around ten weighing results per second are determined until a preset weighing time has elapsed. The
balance then determines the mean value and displays this as the weighing result "dw".
You can also statistically evaluate your dynamic weighings.
Applications – Dynamic weighing
In dynamic weighing you have the following functions and information available in
the bottom line of the display:
"Start" for starting the weighing manually
"n=..." item counter with number of weighings performed
"dw=…" result of the last dynamic weighing or one of the selections specified
under "Results"
"Results" selection of one of the 5 results that should always be shown in the
bottom line during dynamic weighing
"Clear" sets item counter and all results to zero, ends the weighing series
"WghTime" duration of the dynamic weighing, selectable between 1 s and 20 s
extended basic functions (see section 4) if activated in the menu

Requirement
For dynamic weighing, "Dynamic" must be selected under "APPL" in the menu (section 6.1). Further, you can use the menu to
select whether dynamic weighing should start manually or automatically when a load is placed on the balance ("Start ->
Manual" or "Start -> Auto") and what minimum weight ("MinWeight") has to be exceeded for the weighing to start
automatically.
If the application is active, "DYNAMIC WEIGHING" and the , symbol appear in the display after return to the weighing mode.
Press SmartBar under "WghTime".
Select desired duration, e.g. 2 seconds.
Press H to confirm selection.
1. Setting duration of weighing time
The factory setting corresponds to a duration of 3 seconds. If a different setting of the
weighing time is required, proceed as follows:
Press SmartBar under "/" to obtain further selections.
