പ്രധാനപ്പെട്ടത്: The meter supports either voltage input (AI) or current input (mA), but not both simultaneously. Connect your sensor output to the appropriate terminal.

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

5.1. Button Functions and Display States

The meter features four buttons for navigation and parameter adjustment: SET, UP (↑), DOWN (↓), and OK. The 4-digit digital display shows the measured value or parameter settings.

ബട്ടൺ പ്രവർത്തനങ്ങൾ:

• സജ്ജമാക്കുക: Enters parameter setting mode or cycles through parameter groups.
• UP (↑): Increases value or navigates up in menus.
• DOWN (↓): Decreases value or navigates down in menus.
• ശരി: Confirms selection or saves parameter changes.

Digital Tube Display State Transition Diagram:

The meter typically displays the measured value. Pressing the SET button allows entry into the parameter setting menu. Use UP/DOWN to navigate and OK to select/confirm. Pressing SET again will exit the parameter setting mode or move to the next parameter group.

5.2. പാരാമീറ്റർ ക്രമീകരണങ്ങൾ

The meter's functionality is configured through various parameters organized into groups. To enter the parameter setting mode, press the സെറ്റ് ബട്ടൺ. ഉപയോഗിക്കുക UP ഒപ്പം താഴേക്ക് മൂല്യങ്ങൾ ക്രമീകരിക്കാനുള്ള ബട്ടണുകളും OK സ്ഥിരീകരിക്കാൻ. അമർത്തുക സെറ്റ് to move between parameters or exit.

5.2.1. F0-0 Displayed Quantity Collection Parameters

കുറിപ്പ്: The displayed value is a default percentage. You can set your own display range using F0-2 to F0-4.

5.2.2. F1-0 Parameter Group Configuration Parameters

കുറിപ്പ്: By setting the polarization parameter (F1-2) and gain parameter (F1-3), the meter can be adapted to other input ranges within 0-10V or 0-20mA.

5.2.3. F2-0 Parameter Group Relay Output Parameters (for Relay Output Version)

കുറിപ്പ്: These parameters are only applicable to the version of the meter equipped with a relay output. The Standard Edition may not include this feature.

5.3. RS485 Communication Parameters (for RS485 Version)

This section applies only to the Digital Display Meter with RS485 interface. It uses the standard Modbus-RTU protocol for communication.

ചിത്രം 5.1: Comprehensive parameter tables including F0, F1, F2, and RS485 communication settings.

Modbus-RTU Protocol Details:

The meter supports standard Modbus-RTU protocol. The communication parameters (address, baud rate, data format) must be configured correctly to match the master device. The image also shows a table of Modbus register addresses for various parameters (e.g., F0-0, F0-1, F1-0, etc.) which can be read or written via Modbus commands.

For detailed Modbus register addresses and functions, refer to the provided diagram (Figure 5.1) or the official Modbus communication guide for this device. Example: To read F0-0, use Modbus function code 03 (Read Holding Registers) with the corresponding address.
