2. Safety Information

Please read and understand all safety instructions before operating the MATRIX MPM-1010B power meter. Failure to follow these instructions may result in electric shock, fire, or damage to the instrument.

• Always connect the instrument to a properly grounded power outlet.
• Do not operate the meter in wet or damp conditions.
• Ensure the power supply voltage switch (110V/220V) on the rear panel matches your local power supply before connecting the power cord.
• Do not exceed the maximum input voltage of 300V or maximum current of 10A.
• Disconnect power to the device under test before making or changing connections.
• Refer all servicing to qualified personnel. There are no user-serviceable parts inside.
• Keep the instrument away from strong electromagnetic fields.

4. Setup and Connection

Follow these steps to set up your MATRIX MPM-1010B power meter:

1. Power Supply Voltage Selection: Locate the power supply voltage switch on the rear panel (Figure 4, item 5). Ensure it is set to match your local power supply (110V or 220V).
2. Connect Power: Connect the provided power cord to the "Power Input" port on the rear panel (Figure 4, item 4) and plug the other end into a grounded AC outlet.
3. Connect Device Under Test (DUT):
   • Connect the AC power source for your DUT to the "AC SOURCE Input" port on the rear panel (Figure 4, item 1).
   • Connect the DUT itself to the "LOAD Output" port on the rear panel (Figure 4, item 2).
4. RS-232 Connection (Optional): If you wish to connect the meter to a computer for data logging or control, use an RS-232 serial cable to connect the "RS-232 Port" (Figure 4, item 3) on the rear panel to your computer's serial port or a USB-to-serial adapter.

5. Power On: Press the "POWER" button on the front panel (Figure 3, item 6) to turn on the instrument.

5. Operating Instructions

Basic Measurement:

Once powered on and connected to a load, the MPM-1010B will automatically display the measured values on its four-window display:

• Voltage (V): Top-left display.
• Current (A): Top-right display.
• Power (P): Bottom-left display.
• Apk / PF / F: Bottom-right display, cycling between Peak Current (Apk), Power Factor (PF), and Frequency (F).

Setting Upper and Lower Limits (Alarm Function):

The MPM-1010B allows you to set upper and lower limits for Current (A) and Power (P) to trigger sound and light alarms.

1. Press the SETUP button (Figure 3, item 5) to enter the setting mode.
2. Use the Up/Down Arrow buttons (Figure 3, item 3) to navigate through the parameters (e.g., A-High, A-Low, P-High, P-Low).
3. Once the desired parameter is selected, press OK (Figure 3, item 7) to edit its value.
4. Use the Up/Down Arrow buttons to adjust the numerical value.
5. Press OK again to confirm the new value.
6. Press SETUP to exit the setting mode.

When a measured value exceeds the set upper limit or falls below the set lower limit, the corresponding "High" or "Low" LED indicator (Figure 3, item 8) will illuminate, and an audible alarm will sound (if enabled).

Lock/Unlock Display:

Press the Lock/Unlock button (Figure 3, item 2) to freeze the current readings of Voltage, Current, Power, and Power Factor on the display. Press it again to unlock and resume real-time measurements.

Adjusting Volume:

Use the Volume Output Switch (Figure 3, item 4) to enable or disable the audible alarm sound.

RS-232 Communication:

For detailed data logging and analysis, connect the MPM-1010B to a computer via the RS-232 port. Refer to the separate RS-232 communication protocol document (if provided by MATRIX) for software requirements and command sets.
