USING SCALE
WEIGHING
Switch on the scale using key. The diagnostic scale
self-check is performed and the software version is displayed.
The „0,00 kg” weight displays on the screen, now the scale is
ready for weighing.
Place a person in the middle of the scale. Wait until the scale
stabilizes and stable sign (ο) shows on the screen
Direction:
If a person is heavier than the scale capacity, the display will show
the „Err” prompt (= overload).
USING TARE FUNCTION
Tare allows the user to zero the instrument to cancel the weight of a
container/ clothes from the reading of the instrument, thus giving the
true weight of the animal being tested.
Place the object need to be tare on the tread platform.
Press TARE key after the weight stabilizes and stable sign
displays.
Move the animal need to be weighed on the scale
platform(without removing the tare object)
To delete the saved tare value, remove the tare object from the tread
platform and press [TARE] key.

USING HOLD FUNCTION
AW-300P is provided with the integrated hold function (determination
of average value). It enables animal to be weighed accurately
although they are not still on the scale plate. Once the HOLD key is
pressed, the weight reading will remain on the display even after the
animal has been moved from the scale platform, so the reading can
easily be read.
Note: Determination of average value is not possible if the animal is
moving too much.
Switch ‘ON’ the scale using [ON/OFF] key. The diagnostic
self-checks is performed. The scale is ready for weighing when
the „0.0 kg” displays on the screen.
Place animal in the center of the scale plate.
Press the [HOLD] key. When the triangle is flashing on the
display, the scale records the fluctuating weight values and then
calculates average weight and displays the result on the screen.
Move the animal from the scale platform, the weight reading will
remain on the display.
Press the [HOLD] key again to return the scale to the normal
weighing mode.
HOLD function can be activated before or after putting the
weight on the tread platform. But in case of weighing unstable
animal it is recommended to press HOLD key before the animal
moves on the tread platform.
