4.1. Key Features

• Measures Voltage, Current, Frequency, Active Power, Reactive Power, Apparent Power, Power Factor.
• RMS measurement with accuracy class 0.5.
• Programmable 2, 3, or 4 rows of LED display.
• RS-485 digital interface with MODBUS-RTU protocol.
• 2 channels of energy pulse output (optocoupler isolation).
• Wide working range: AC, DC80~270V.

5. Setup and Installation

Proper installation is crucial for the accurate and safe operation of the meter. Follow these steps carefully:

5.1. Mounting the Meter

1. Prepare a panel cutout of appropriate dimensions for the meter (refer to specifications for exact size).
2. Insert the meter into the cutout from the front of the panel.
3. Secure the meter using the provided transparent mounting accessories and screws from the rear of the panel. Ensure it is firmly seated.

5.2. Wiring Connections

All wiring must be performed with the power supply disconnected. Refer to the wiring diagram for your specific application (e.g., 3-phase 3-wire, 3-phase 4-wire).

• Power Supply: Connect the AC/DC 80~270V power supply to the designated terminals.
• Voltage Inputs: Connect the phase voltages (L1, L2, L3) and neutral (N) to the corresponding voltage input terminals.
• Current Inputs: Connect the secondary of current transformers (CTs) to the current input terminals. Ensure correct polarity (P1/S1 and P2/S2). Do not open the secondary circuit of a CT while the primary is energized.
• RS-485 Communication: Connect the RS-485 A and B lines to the respective communication terminals for MODBUS-RTU protocol.
• Pulse Output: If using, connect the energy pulse output terminals to your monitoring system.

After all connections are made, double-check for correctness and security before restoring power.

6. Operating Instructions

Once the meter is powered on, it will display the measured parameters. The display can be navigated using the front panel buttons.

6.1. Display Navigation

• Left/Right Arrow Buttons: Use these buttons to cycle through different display screens, showing various electrical parameters (e.g., voltage, current, power, frequency, energy).
• Menu Button: Press the 'Menu' button to enter the configuration menu.
• Enter Button: Use the 'Enter' button (often combined with the right arrow) to confirm selections or enter sub-menus within the configuration.

6.2. Configuration (Advanced)

The meter allows for configuration of parameters such as CT ratio, PT ratio, communication settings (baud rate, address), and display modes. Access this through the 'Menu' button. Refer to the detailed programming guide (if provided separately) for specific menu structures and parameter adjustments.

Incorrect configuration can lead to inaccurate readings or communication issues. Proceed with caution when adjusting settings.

7. Maintenance

The Agatige 96-UIF Multi-Function Meter requires minimal maintenance to ensure long-term reliable operation.

• Cleaning: Gently wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Periodically inspect wiring connections for tightness and signs of wear or corrosion.
• Environment: Ensure the operating environment remains within specified temperature and humidity ranges.
