1.GENERAL DESCRIPTIONS
WEI uses high reliability, good accuracy weighing devices, including wireless weighing indicator, high
precision load cell and the most advanced ∆-∑ type A / D converter.
WEI Wireless indicator is a wireless industrial weighing indicator that can communicate up to 100
meters in an open area designed especially for axle scales, cranes and dynamometers.
WEI, which can be connected to 16 different load cells, can display all incoming weight information
individually and in total on the graphic display.
8 load cells (350 Ohm) can be connected to the wireless transmitter module it works with.
Tensile and breakout tests can be performed with the Peak hold feature.
When more than one balance is connected, it can zero and tare each scale separately.
It can be connected to computers and printers with RS232 output.

value can be deleted with the Clear key.
Performs zero calibration in weighing condition.
Each time it is pressed, it sends the weight information to the printer.
It is used to enter the menus and to switch the menus.
Enters the Peak menu. Keeps the current peak value of the weighing. The desired scale can
be selected with the up arrow or down arrow.
Deletes total weighing record or deletes tare in Tare menu.
Turns the screen backlight on or off.
Enters the tare menu. It is used for net weight display. The desired scale is selected with the

4. USE OF THE DEVICE
1) This icon indicates the wireless signal strength. If there is more than one transmitter, it shows the
signal strength of the farthest transmitter. If no transmitter sends a signal, a no signal sign will
appear.
2) The display of the STB icon indicates that the weight weight data has become steady state.
3) Displaying the Tare icon shows the net weight of the weigh weight data.
4) The display of the M + symbol indicates that the weighing weight data has been saved.
5) This icon shows the battery status.
6) This value shows the sum of weighing weight data.
7) This icon shows the unit of the weighing weight data.
8) Shows the time.
9) Shows the date.
10) M + key gathers the weight value on the screen and keeps it in memory.

4.2 SINGLE SCREENING FORM
Press the key to switch from the main display to the single display.
In single display, the transmitter number and the load value are displayed opposite it. If the
transmitters do not work or there is no signal, the line is shown.
4.3 RESET SCREEN
Press the key to enter the reset menu.
Group reset or single reset is selected to reset the weighing. If group reset is selected, all of the scales
are reset. If single reset is selected, the desired scale can be reset. Press * ESC + key to exit the menu
and return to the main display.
In group reset, the total of weighing weight data of the scales is displayed. In this menu if you press
the key resetting is done in all scales. Press * ESC + key to exit the menu and return to the main
display.

In the single reset menu, the desired scale is selected with the up arrow or down arrow and the
weighing weight data of the selected scale is displayed on the screen.In this menu if you pres the
key, resetting is done in the selected scale. Press * ESC + key to exit the menu and return to the
main display.
4.4 PEAK SCREENING
Press the key to enter the Peak menu.
The Peak weight menu keeps the peak value of the current weighing weight data. Scales can be
selected with up arrow or down arrow. *Clear + key brings the value on the screen to the current
weight value. Press * ESC + key to exit the menu and return to the main display. After exiting this
menu, the captured peak value will not be lost.
4.5 TARE SCREENING
Press the key to enter the tare menu.
The taring menu is used to display the net weight. Scales can be selected with up arrow or down
arrow. If the key is pressed, the weight value of the selected scale is taken as tare and the screen
is reset. If * Clear + is pressed in this menu, Tare is canceled. After taring, the Tare icon is shown in
the main display. If you want to cancel the tare while in main display, press * Clear + key after
entering this menu and selecting the desired scale. Press * ESC + key to exit the menu and return to
the main display.

4.6 RS232 Output Connection and Printer Format
