Basic Measurement Techniques
Mastering fundamental measurements is key to utilizing the Fluke 87V effectively. This section details voltage, current, resistance, and continuity testing procedures.
Proper probe connection and range selection are crucial for accurate readings. Always prioritize safety when performing electrical measurements.
Voltage Measurement (AC/DC)
Measuring voltage with the Fluke 87V requires selecting the appropriate function on the rotary dial – either DC Voltage (VDC) or AC Voltage (VAC). Ensure the test leads are connected to the correct input terminals: black to COM and red to VΩmA.
For DC voltage, observe polarity; a negative reading indicates reversed leads. When measuring AC voltage, the polarity is irrelevant. Always begin with the highest range and decrease for better resolution, observing safety precautions.
Be mindful of the measurement category rating (CAT III 600V) and use appropriately rated probes. Incorrect range selection or probe usage can lead to inaccurate readings or damage to the meter.
Current Measurement (AC/DC)
Measuring current with the Fluke 87V necessitates a different connection setup than voltage measurements. The test leads must be rearranged: black to COM and red to the mA or A input terminal, depending on the expected current level;
Select the appropriate current function (DC Amps or AC Amps) on the rotary dial. Always break the circuit before connecting the meter in series to measure current; never short-circuit the meter directly.
Start with the highest current range and decrease it for improved accuracy. Exceeding the meter’s current rating can blow the fuse and potentially damage the instrument – replace fuses carefully.
Resistance Measurement
To measure resistance with the Fluke 87V, ensure the circuit is de-energized. Power off the circuit and discharge any capacitors before connecting the test leads.
Select the resistance (Ω) function on the rotary dial. Begin with the highest range and decrease it for a more precise reading, observing the display.
High resistance values may take longer to stabilize. Note that body resistance can affect low-resistance measurements; avoid touching the metal parts of the probes during testing.
Continuity Testing
The Fluke 87V’s continuity test quickly checks for unbroken electrical paths. Select the continuity function (diode symbol with a sound wave) on the rotary dial.
Touch the probe tips to the points you want to test. A beep indicates a closed circuit (low resistance), signifying continuity. If no beep sounds, the circuit is open.
Ensure the circuit is de-energized before testing. Be aware that stray capacitance can sometimes trigger a false continuity indication; verify results if uncertain.
Advanced Features and Functions
The Fluke 87V offers diode testing, frequency measurement, capacitance checks, and temperature readings. These functions expand diagnostic capabilities beyond basic measurements.
Utilize these tools for in-depth circuit analysis and component verification. Explore FlukeView Forms for data logging and detailed analysis options.
Diode Test Mode
The Fluke 87V’s diode test mode efficiently checks the forward voltage drop of diodes. This function verifies diode functionality by applying a small current and measuring the voltage across the diode.
A forward-biased, good diode typically displays a voltage drop between 0.5V and 0.8V. An open diode will show “OL” (Over Limit), indicating no conduction, while a shorted diode will display 0V.
This test is crucial for identifying faulty diodes in circuits. Remember to disconnect power from the circuit before testing and isolate the diode if possible for accurate results.
Frequency Measurement
The Fluke 87V’s frequency measurement function determines the number of cycles per second (Hertz) of an AC signal. This is vital for analyzing waveforms and identifying signal characteristics.
To use this feature, select the frequency measurement range on the function dial. Connect the test leads to the signal being measured, ensuring proper polarity isn’t critical for frequency.
The display will show the frequency value. Note that the accuracy depends on the signal’s amplitude and waveform shape; clean sine waves yield the best results.
Capacitance Measurement
The Fluke 87V accurately measures capacitance, the ability of a component to store an electrical charge, in Farads. This function is crucial for testing capacitors and verifying circuit performance.
Select the capacitance range on the function dial and disconnect power from the circuit before connecting the test leads. Connect leads to the capacitor’s terminals, observing polarity if applicable.
The display shows the capacitance value. Ensure the capacitor is discharged before measurement to avoid damage and obtain accurate readings; larger capacitors may take time to stabilize.
Temperature Measurement
The Fluke 87V, when used with a compatible temperature probe (sold separately), accurately measures temperature in Celsius or Fahrenheit; This function is vital for HVAC, industrial maintenance, and various scientific applications.
Connect the temperature probe to the meter and select the temperature function on the dial. Ensure the probe is properly positioned for accurate readings, avoiding direct contact with electrical circuits.

Troubleshooting Common Issues
This section addresses typical problems with the Fluke 87V, including power failures, inaccurate readings, and continuity beep malfunctions. Fuse replacement guidance is also provided.
No Power/Display Issues
If the Fluke 87V fails to power on, first verify the battery’s condition. Replace with a fresh battery, ensuring correct polarity. Check the battery compartment for corrosion or damage.
Next, inspect the fuse located on the rear panel. A blown fuse indicates a potential internal fault; replace it with the specified type and rating only. If the issue persists, there may be a problem with the power supply circuitry, requiring professional service.
A dimly lit or blank display could also signal a low battery or internal component failure.
Incorrect Readings
If the Fluke 87V provides inaccurate measurements, begin by verifying probe connections. Ensure probes are firmly seated in the correct input terminals. Check for damaged or low-quality test leads, as these can introduce errors.
Confirm the function selection dial is set to the appropriate measurement type (AC/DC voltage, current, etc.). Recalibration may be necessary if readings consistently deviate from known standards.
Internal component drift or damage can also cause inaccuracies, necessitating professional repair and calibration.
Continuity Beep Not Working
If the continuity beep fails to sound, first ensure the function dial is correctly positioned to the continuity test setting. Verify the test leads are securely connected to the appropriate terminals, and that the probes are making good contact with the circuit under test.
A discharged battery can sometimes suppress the beep; replace the battery to rule this out. Internal issues with the buzzer or associated circuitry may require professional service.
Check for open circuits or high resistance in the test leads themselves.
Fuse Replacement Procedures
Before replacing any fuse, disconnect all test leads and power sources. Always use only Fluke-approved replacement fuses with the correct current and voltage ratings to prevent damage or safety hazards. Locate the fuse compartment, typically on the rear panel.
Carefully remove the old fuse and insert the new one, ensuring proper orientation. Never attempt to bypass or bridge a fuse – this is extremely dangerous.
If the new fuse blows immediately, a more serious internal fault exists, requiring professional repair.
Safety Precautions and Guidelines
Always follow general safety rules and measurement category ratings (CAT III 600V). Use proper probes and inspect for damage before each use.
