6. Operation and Parameter Settings
This section describes how to operate the meter and configure its various parameters using the front panel buttons.
6.1. Indicator Lights
- "RS485 version":
- R: Indicates data reception.
- T: Indicates data transmission.
- "Relay output version": The indicator light illuminates when the relay is closed.
6.2. Button and Display State Transition
The meter features a multi-level menu system for configuration. Use the SET, Up Arrow, Down Arrow, and OK buttons to navigate and adjust settings.
Figure 6.1: Button and digital tube display state transition diagram. This diagram illustrates how to navigate through the menu levels (Monitoring, First-level, Second-level, Third-level) using the SET and OK buttons, and how to modify parameters using the Up/Down arrows.
Special Note: When in the third-level menu, pressing the OK key saves the modified parameter values and returns to the previous menu level, with the parameter number automatically incremented by one. Pressing the SET key returns directly to the previous menu level without saving the modified parameter values. Holding down the Up or Down key allows the adjustment values to change rapidly.
6.3. Parameter Group F0: Attendant Array Display
These parameters relate to the display and monitoring of the input value.
| Parameter | Parameter Name | Scope and Description | Defaults | Read/Write |
|---|---|---|---|---|
| F0-0 | Collected value monitoring | Monitor the percentage of the current analog input value. Range: 0-100.0% | read-only | |
| F0-1 | Display value monitoring | In the display value in "Monitoring Menu" is calculated by F0-0, F0-2~F0-4. | read-only | |
| F0-2 | Display accuracy | The number of decimal places displayed in the "Monitor Menu", range: 0-3. | 1 | Read/write |

| F0-4 | Show maximum | In the "Monitoring Menu", the value corresponding to the "Acquisition Value" is 100.0%, the range: 1999~9999 | 1000 | Read/write |
| F0-5 | Offline status | 0: Not disconnected; 1: Disconnected. (Disconnection detection is set by F1-4) (starting from V2.10) | read-only |
6.4. Parameter Group F1: Analog Configuration Parameters
These parameters configure the analog input signal processing.
| Parameter | Parameter Name | Scope and Description | Defaults | Read/Write |
|---|---|---|---|---|
| F1-0 | Input type selection | 0: 0-10V or 0-20mA corresponds to 0-100.0%; 1: 2-10V or 4-20mA corresponds to 0-100.0%, and 0 when it is lower than 2V or 4mA. | 0 | Read/write |
| F1-1 | Input filter time | Analog input filter time, range: 0-10.000s. The longer the filtering time, the stronger the filtering. | 0.200 | Read/write |
| F1-2 | Input gain | Range: 0-1000.0%. | 100.0 | Read/write |
| F1-3 | Input offset | -99.9~99.9%, with 10V or 20mA as 100.0%. Range: 0.0-100.0%. This value is based on 0-10V or 0-20mA as 0.0-100.0% as a reference (and F1-0 and gain offset are not related). | 0.0 | Read/write |
| F1-4 | Drop detection threshold | The detection is not started if it is less than 0.5, and there is a hysteresis of ±0.3. When the input signal is lower than this value, the meter displays E.OfL. (Starting from V2.10) | 0.0 | Read/write |
| F1-5 | Enter the parameter setting selection | 0: Long press SET button for 3s to enter the parameter setting mode; 1: Keep pressing SET button for more than 3s, and Press OK to enter parameter setting mode | 0 | Read/write |
6.5. Parameter Group F2: Relay Output Dosing (with Relay Output version)
These parameters are applicable only to meters with relay output functionality.
| Parameter | Parameter Name | Scope and Description | Defaults | Read/Write |
|---|---|---|---|---|
| F2-0 | Relay output status configuration | When the output conditions are met, the relay output status: 0: No control (always open); 1: Relay closed; 2: Relay open (not satisfied Closed on condition) | 0 | Read/write |
| F2-1 | Condition type | 0: greater than comparison value 1; 1: less than comparison value 2; 2: greater than comparison value 1 and less than comparison value 2. | 0 | Read/write |
| F2-2 | Comparison value 1 | Range: 0-100.0%. | 50.0 | Read/write |
| F2-3 | Comparison value 2 | Range: 0-100.0%. | 50.0 | Read/write |
| F2-4 | Hysteresis interval | In order to prevent the relay output from operating frequently near the comparison value, hysteresis interval parameters are introduced. Range: 0.0%-80.0%. | 5.0 | Read/write |
| F2-5 | Relay status when offline | After setting F1-4, when the offline condition is reached, the relay output state. Note: This priority is higher than that of the comparison relay output. 0: Not used; 1: Relay is closed; 2: Relay is disconnected (starting from V2.10) | 0 | Read/write |
Example of Hysteresis Interval: For example, if F2-1 (Condition type) is set to "0: greater than comparison value 1", F2-2 (Comparison value 1) to 50.0%, and F2-4 (Hysteresis interval) to 5.0%. When the power is on, if the collected value gradually increases and exceeds 50.0%+5.0%/2, the output condition is satisfied. If the collected value decreases, it needs to be less than 50.0%-5.0%/2 to reach the non-output condition.
7. RS485 Communication (with RS485 Version)
This section details the communication parameters and networking for the RS485 version of the meter.
7.1. Parameter Group F7: Communication Parameters and Software Version
| Parameter | Parameter Name | Scope and Description | Defaults | Read/Write |
|---|---|---|---|---|
| F7-0 | Local address | Range: 1-247 | 1 | Read/write |
| F7-1 | Baud rate | 0:1200bps; 1: 2400bps; 2: 4800bps; 3: 9600bps; 4:19200bps; 5: 38400bps | 3 | Read/write |
| F7-2 | Data Format | 0:8,1, None (8 data bits, 1 stop bit, no parity); 1:8,1, Even (8 data bits, 1 stop bit, even parity); 2:8,1, Odd (8 data bits, 1 stop bit, odd parity); 3:8,2, None (8 data bits, 2 stop bits, no parity) | 0 | Read/write |
| F7-3 | Response delay | Communication response delay time 0~500ms. Use above V1.02 | 5 | Read/write |
| F7-4 | Communication type | 0: The display table is a Modbus slave, and the user host can read the collected values of the display table; 1: The display table is a network slave between the tables, and can receive the display data of the display table set as the master; 2: The display table is the network host between the tables, and the display value is sent to the slave display table through the broadcast address; 3: The display table is the inter-table networking host, and the display value is sent to the slave by means of address polling. | 0 | Read/write |
7.2. Communication Protocol and Method
The meter uses a Modbus-like protocol for communication. The following describes how to interact with the meter as a slave device.
7.2.1. Reading Collected Values from the Display Table
The user host can read the collected values (F0-0) and display values (F0-1) from the meter. The meter's display range is determined by F0-2 to F0-4. The Modbus register address for F0-0 is 0000H, and for F0-1 is 0001H. The collected value is 0-1000, corresponding to 0-100.0%. The display value is 0-1000, corresponding to the display range set by F0-2 to F0-4. The host can also read and write other parameters (F0-2 to F0-4, F1-0 to F1-5, F2-0 to F2-5, F7-0 to F7-4).
Example: If the collected value F0-0 is 60.0%, the displayed value F0-1 is 60.0. The slave (HXDSBOXAI) response data for reading F0-0 and F0-1 would be:
- Slave address (F7-0): 01H
- Modbus function number: 03H
- Start address (high byte): 00H
- Start address (low byte): 00H
- Read word count (high byte): 00H
- Read word count (low byte): 02G
- CRC (low byte): C4H
- CRC (high byte): 0BH
In the above example, the read F0-0 and F0-1 are 0258H = 600, meaning the collected value F0-0 is 60.0%, and the displayed value F0-1 is 60.0.
7.3. Networking Description Between Tables
Through the network between meters, the display value of the data collected by the master meter can be transmitted to the slave meter for display through RS485. Only one master table can exist in a network, and there can be multiple slave tables. In use, only the master table needs to set the corresponding display range, and the slave table does not need to set the display range.
7.3.1. Main Table Sends Data Through Broadcast Mode Network Diagram
Figure 7.1: Main table sends data through broadcast mode network diagram. This diagram illustrates a master meter (Main table, F7-4 is 2) broadcasting data to multiple slave meters (From table, F7-4 is 1) over an RS485 total line.
7.3.2. Table Network Diagram of Sending Data Through Address Polling
Figure 7.2: Table network diagram of sending data through address polling. This diagram illustrates a primary master meter (F7-0 is 3, F7-4 is 3) polling data from multiple slave meters (F7-0 is 1, F7-4 is 1; F7-0 is 2, F7-4 is 1) over an RS485 total line.
Note: When the master meter sends data to the slave meter through address polling, only meters with the same address as the polled address will respond. All other meters will not respond. This ensures targeted communication in a multi-device network.
8. Maintenance
- Keep the meter clean and free from dust and moisture.
- Avoid exposing the device to extreme temperatures or direct sunlight.
- Do not use abrasive cleaners or solvents on the display or casing.
- Ensure all wiring connections remain secure. Periodically check for loose connections.
- If the device requires cleaning, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device.
9. Troubleshooting
- No Display:
- Check power supply connections (PWR, GND) and ensure the voltage is within the specified range (DC6~25V or DC8~25V depending on version).
- Verify that the power supply is active.
- Incorrect Reading:
- Ensure the input signal type (F1-0) is correctly configured for your sensor (0-10V, 2-10V, 0-20mA, 4-20mA).
- Check wiring for the analog input (Ai, mA, GND) to ensure it matches the sensor output.
- Review F1-2 (Input gain) and F1-3 (Input offset) parameters for proper calibration.
- Confirm the display range parameters (F0-3, F0-4) are set correctly.
- RS485 Communication Issues:
- Verify RS485 wiring (485+, 485-).
- Check F7-0 (Local address), F7-1 (Baud rate), and F7-2 (Data Format) parameters to ensure they match the master device settings.
- Ensure the communication type (F7-4) is correctly configured for your network setup (slave, broadcast host, polling host).
- Check the R and T indicator lights for activity.
- Relay Not Activating (Relay Output Version):
- Check F2-0 (Relay output status configuration) to ensure it's not set to "No control".
- Verify F2-1 (Condition type), F2-2 (Comparison value 1), and F2-3 (Comparison value 2) are set to trigger the relay under desired conditions.
- Consider the F2-4 (Hysteresis interval) which might prevent frequent switching.
- Check F2-5 (Relay status when offline) if the meter is in an offline state.
If issues persist after checking these points, consult the manufacturer's support or a qualified technician.
