APW Optimization – Since the weight of each piece varies slightly, APW Optimization may be used to increase the
accuracy of the count. The balance automatically recalculates the Average Piece Weight when the number of parts
on the pan is less than three times the original sample size. The display shows [APwW.OPT] each time the APW is
optimized.
– Use this mode to measure the weight of a sample as a percentage of a reference weight.
3.3 Percent Mode
To access the Percent Mode, press Unit until the display shows [PErCEnt].
Establish a new Reference Weight - With Clear reference [CLr.rEF] displayed, Press No to use the previously
saved Reference Weight. Press Yes to establish a new Reference Weight. Put the reference sample on the pan
and press Yes to accept or No to abort.
Percent – Place the object(s) to be compared to the reference weight on the pan.
– Use this mode to weigh an unstable load, such as a moving animal.
3.4 Dynamic Mode
To access the Dynamic mode, press Unit until the display shows [Dyn].
Two different start/reset modes can be selected: Manual (start and stop via key press), Automatic (start and stop
automatically).
The default Averaging Time is 5s.
After accessing this mode, the two "0/T" buttons will have different functions as shown in below picture.
Set up Averaging Time-The default Averaging Time is 5s.The initial display shows [t 5].
The time "t5" is blinking. Press No to scroll the time selection 5, 10, 15, 20 and 30. The time unit is s (second).
Press the right 0/T button to select the desired option. After time is set, dynamic weighing will begin.
Begin Dynamic Manual mode-If there is no weight (less than 10d), the display shows [PUt] and [wWeigHt]
alternately. Place object(s) on weighing pan (more than 10d), the display shows the current weight value. Press
the left 0/T button to zero or tare if needed. Press the right 0/T button to start the dynamic weighing. The count
down is shown on the display, eg: "t 5", "t 4",... "t 1". Once the averaging is finished, the result is displayed
(blinking).
Press the right 0/T button to stop the blinking and go back to ready status.
Begin Dynamic Auto mode-If there is no weight (less than 10d), the display shows [PUt] and [weigHt] alternately.
Place object(s) on weighing pan (more than 10d); the dynamic weighing will be started automatically. The count
down is shown on the display, eg: "t 5", "t 4",... "t 1". Once the averaging is finished, the result is displayed
(blinking).
Remove the object(s), or press the right 0/T button, to clear the result and go back to ready status.
-- Use this mode to determine an object's density.
3.5 Density Mode
A density determination kit is needed to use this mode. For liquid density determination, one more sinker is
needed.
To access the Density mode, press Unit until the display shows [Density].
After accessing this mode, the two "0/T" buttons will have different functions as shown in below picture.
Begin Density Solid mode-The display shows [Air] and [weigHt] alternately. Place object(s) on the density
determination kit (in the air), the display shows the weight value.
Press the right 0/T button to accept the weight as air weight.
The display shows [Liguid] and [wWeigHt] alternately. Place object(s) on the density determination kit (in the
liquid), please make sure that the entire object is submerged in the liquid, the display shows the weight value.
