I communication connection
1. As shown in Figure 1, first select the correct port, then select the correct
baud rate (default 9600) and address according to the wiring diagram
identification printed on the meter side, at last click “open the serial port”.
Figure 1
If Figure 2 pop-up, you need to check whether the selected port exists or is
occupied.
Figure 2
2. Click communication, observe until the times of sending and receiving are
equal (like Figure 3), which indicating that the communication between PC and
meter is normal. Other parameters can be modified at this time.
Figure 3
II Modify address
As shown in Figure 4, when the meter communicates normally, input the
address to be set in the text box on the right side of "set address", then click
"set address" to set the parameters.
Figure 4
When the dialog box as shown in Figure 5 pops up, the setting is successful.

If the setted general addresses get lost, it can be read through universal
address 255 (when networking communication, must use general address).
III Modify baud rate
As shown in Figure 6, when the meter communicates normally, select the
required baud rate in the drop-down box on the right side of "set baud rate",
and click "set baud rate" button to save the baud rate after selection.

The transformation ratio is corresponding from top to bottom:
CT1— Hall sensor No.4 No.5
CT2— Hall sensor No.6 No.7
CT3— Hall sensor No.8 No.9
CT4— Hall sensor No.14 No.15
CT5— Hall sensor No.16 No.17
CT6— Hall sensor No.18 No.19
The value of the transformation ratio is determined by the hall sensor
accessed into the channel. Fox example, if port 4 and 5 connect 200A/5V hall
sensor, the ratio is 40. Port 6 and 7 connect 100A/5V, the ratio is 20.
After the change ratio of the corresponding channel is correctly filled, click the
"set change ratio" button to modify the parameters. After modification, click
read ratio to check whether modification is completed.

VI Zero Calibration
1.Preparation
Before performing the hall sensor zero calibration, the hall sensor must be
removed from the power line to ensure the hall sensor is in an unload state.
Then tighten the screws, ensuring that the hall sensor corresponding to the
channel to be calibrated is in a normal working state.
2.Hall Sensor zero calibration
As shown in Figure 1, select the correct channel number according to the
corresponding channel of the Hall to be calibrated; for example, the hall sensor
corresponding to the terminal number 4 and 5 needs to be calibrated, select
"Channel 1", and then click “Zero Calibration" to enter the channel 1 zero point
calibration mode (as shown in Figure 3). If all channels need to be zeroed,
select "Channel All", and then click "Zero Calibration" to enter the zero point
calibration mode for all channels (as shown in Figure 3). When the pop-up
"Zero Calibration Failed" means the Hall zero calibration failed, when the
pop-up "Zero Calibration Successfully" means the Hall zero calibration was
successful;
