3. Setup
Before first use, ensure the multimeter is properly set up and test leads are connected securely.
- Battery Installation: The Fluke 87V Max typically comes with batteries pre-installed. If not, refer to the battery compartment on the rear of the device for proper installation. Ensure correct polarity.
- Attaching the Holster: The removable holster provides protection and can be used as a test probe holder. Slide the multimeter into the holster until it fits snugly.
- Connecting Test Leads: Insert the banana plugs of the test leads into the appropriate input jacks on the multimeter. For most measurements, the black lead connects to the COM (common) jack and the red lead connects to the VÅHz or mA/µA jack, depending on the measurement type. For current measurements up to 10A, use the 10A MAX FUSED jack.
- MC4 Test Lead Bundle: For solar PV array measurements, connect the specialized MC4 test leads to the meter. These leads are designed for direct connection to MC4 connectors found on solar panels.

4. Operating the Multimeter
The Fluke 87V Max offers a wide range of measurement functions. Always select the correct function and range before making a measurement.
4.1. Basic Measurements
- Voltage (V): Turn the rotary switch to VÅHz. Select AC or DC voltage using the yellow function button if necessary. Connect leads in parallel with the circuit.
- Current (A): Turn the rotary switch to mA/µA or 10A. Select AC or DC current. Connect leads in series with the circuit. Ensure the correct input jack is used (400mA FUSED or 10A MAX FUSED).
- Resistance (Å): Turn the rotary switch to VÅHz and press the yellow button to select resistance. Connect leads across the component.
- Continuity: Turn the rotary switch to VÅHz and press the yellow button to select continuity. The meter will beep if there is a continuous path.
4.2. Advanced Features
- True-RMS: The 87V Max is a True-RMS meter, providing accurate readings for non-sinusoidal waveforms, which are common in modern electrical systems.
- Min/Max/Average: Press the MIN MAX button to capture minimum, maximum, and average readings over time.
- Peak Min/Max: Use this function to capture transient peaks as fast as 250 µs.
- Frequency (Hz) and Duty Cycle (%): Measure the frequency and duty cycle of AC signals.
- Capacitance: Measure the capacitance of capacitors.
- Temperature: Use the included temperature probe to measure temperature.
