4.5.2 6-wire connection method of load cell
In order to increase the stability of the weighing signal at a long distance,
the instrument and the sensor can be connected with a 6-wire system (long-line
compensation mode), and the sensor should adopt a 6-core shielded wire, and it
should be wired separately from the lines with strong interference (power equipment
wiring, etc.) and AC lines. (see figure 4.8 below)
4.5.3 Four-wire connection method of load cell
If the distance is close, 4-wire connection method can be adopted. At this
time, "E+" and "F+", "E-" and "F-" must be shorted on the interface terminals of
the host sensor respectively. If it is not short-circuited, the instrument will
not work normally, even sometimes it seems to work normally on the surface, but
it will actually produce a big error, so it must be connected strictly according
to Figure 4.9.

method of load cell
Note: In the above two figures, sensor 1# is taken as an example, and the
connection method of sensor 2# is the same.
4.6 Connection method of communication interface
such asSection 3.1As shown in the interface layout of the instrument host, there is a
communication port on both sides A and B of the instrument host.
Figure 4.10 Schematic diagram of two communication interfaces of the
instrument
The 1# communication port on the surface A is RS485 interface, which is fixed
to the standard Modbus RTU protocol with baud rate of 38400, and can be directly
connected (without any setting) to the display panel produced by our company or
the touch screen sold by our company.
B 2# communication port is a full-function communication port compatible with
RS485 and RS232 at the same time. The communication mode, address and baud rate
can be set. Top loose protocol, standard Modbus RTU protocol and a variety of
continuous transmission modes can be selected. It can communicate with computers,
PLC and other devices.
Note: When the 2# communication port is set to Modbus RTU protocol, it has
the same function as the 1# communication port.
Note: The first interface NC on the left of 2 # communication port is not
connected to any electrical node, and can only be used in special occasions.
4.6.1 Connection Method of Host and Display Panel
There are also two connections to the host display panel. The first one supplies
power to the host, as shown in connection 1 below. If the distance between the
display panel and the host computer is far, connection 2 can be adopted at this
time, and the external power supply is used, and the power supply voltage is 8-12V
DC.

Fig. 4.11 Connection Method between Host and Display Panel
4.6.2 Connection method between host and touch screen
The instrument can directly supply power to the touch screen, or it can be
externally supplied if the distance between the touch screen and the host is far.
Please refer to the relevant information of the touch screen for the power supply
voltage range and connection method.
V. Parameter setting
5.1 Function and operation of setting buttons on the display panel
such asFigure 3.3As you can see, there are 6 independent setting buttons on
the display panel. Each button has two names and performs different functions in
different situations. Each key has two operations: short press and long press.
When a key is pressed, the buzzer will sound short, and then releasing the key
is short press. If you press and hold a key for more than 2 seconds,It is a long

VI. Weighing and calibration of instruments
When the instrument is used for the first time or after using for a period
of time, the weighing error is large, so it is necessary to carry out weighing
calibration.The instrument can be calibrated in kind, and the calculation method
can be used in some cases where the physical calibration cannot be carried out.If
it is the initial calibration, the user needs to set the f parameters related to
weighing before entering the formal calibration step,The parameters involved are:

6.1 Physical calibration
The physical calibration is divided into two steps. The first step is zero
point calibration, and the second step is loading point calibration.Weighing
calibration operation is a user-1 level or above project, you must use the
corresponding password to log in.
The operation of zero point calibration is completed directly through the panel
buttons [reset 1] [set to zero 2]. If you do not log in with a password, the following
operations are performed manually.The specific steps are as follows:
