Troubleshooting Common Issues
Issue #1: Inaccurate Voltage Readings or “Ghost Voltage”
Problem: You’re getting a voltage reading on a circuit you believe should be dead, leading to confusion or unsafe assumptions.
Solution: This is exactly what the low-impedance (LoZ) mode on the Fluke 117 is designed to solve. Switch to the LoZ voltage function. It places a load on the circuit, collapsing any induced or capacitive coupled “ghost” voltage and showing you the true state.
Prevention: Get in the habit of using LoZ mode first when verifying a de-energized circuit for safety.
Issue #2: Clamp Meter Shows Zero on a Live Circuit
Problem: The Fluke 323 clamp is on a conductor you know is carrying current, but it reads zero or near-zero amps.
Solution: First, ensure you’re measuring AC current, as the 323 does not measure DC. Second, verify the clamp is fully closed around a single conductor—if it’s around multiple wires carrying current in opposite directions, the fields cancel out. Third, check that the dial is set to the proper AC Amps range.
Tech Note: The Fluke 323 measures AC current only, up to 400A. It will not read DC current from batteries, automotive systems, or DC power supplies.
Issue #3: Display is Hard to Read or Backlight Won’t Activate
Problem: The digital display on the Fluke 117 is dim, or the backlight doesn’t turn on in low-light conditions.
Solution:
- For the Fluke 117, press and hold the “Hold” button to activate the white LED backlight. It has a timed auto-off to conserve battery.
- Check the battery compartment. Weak batteries can cause display contrast issues. Replace with fresh batteries.
- Ensure the dial is not positioned between two functions, which can cause erratic display behavior.
Issue #4: Meter Readings Seem Inconsistent on Modern Electronics
Problem: When measuring voltage on equipment like VFDs, LED drivers, or UPS systems, readings fluctuate or don’t match expected values.
Solution: Ensure you are using the True RMS function of the Fluke 117. Standard meters give inaccurate readings on non-sinusoidal waveforms. The True RMS function provides the correct heating value of the complex wave, which is the accurate measurement for diagnostics and safety.
Safety Feature: Using True RMS ensures you have accurate data for lockout/tagout procedures on modern non-linear loads.
Issue #5: Accessories Are Missing or Don’t Fit
Problem: You can’t find the TPAK hanger or the test leads don’t seem to make good contact.
Solution: All accessories have a specific place in the included carrying case. Refer to the molded compartments. For test lead issues, ensure the banana plugs are fully inserted into the meter jacks and that you’re using the included TL75 test leads designed for Fluke meters. The TPAK attaches securely to the back of either meter’s holster.

Frequently Asked Questions
Does the Fluke 323 clamp meter measure DC current?
No, the Fluke 323 in this combo kit measures AC current only, up to 400A. It is designed for measuring alternating current in residential and commercial electrical systems, such as motor loads, HVAC compressors, and branch circuit currents. For automotive, battery, or DC power supply work requiring DC current measurement, you would need a different clamp meter model with DC amp capability.
What is the difference between True RMS and a standard multimeter reading?
A standard multimeter calculates voltage based on an average of a perfect sine wave, which can be inaccurate by up to 40% on distorted waveforms. The True RMS (Root Mean Square) function in the Fluke 117 measures the actual heating value of any AC waveform, including the complex, non-sinusoidal waves produced by modern electronics like VFDs, LED drivers, and computer power supplies. This provides accurate, reliable readings essential for professional diagnostics and safety.
Can I buy the Fluke 117 and 323 meters separately, or is this kit a better deal?
You can purchase each meter individually, but the Fluke 117/323 Combo Kit typically offers significant value. Beyond just bundling the two tools, it includes the TPAK magnetic hanger and a dedicated carrying case that are not always included in individual purchases. The kit ensures you have a complete, organized system ready for the job site, often at a lower total cost than buying each component separately.
What does “low-impedance ghost voltage detection” actually do?
This feature (LoZ mode on the Fluke 117) places a low-impedance load (approximately 3kΩ) across the test leads when measuring voltage. This load collapses any induced or capacitively coupled “ghost” voltage that may be present on a de-energized wire running parallel to live conductors. It reveals the true voltage state, which is critical for safely verifying a circuit is dead before working on it, preventing potentially dangerous false readings.
Is this kit suitable for industrial three-phase power work?
Yes, for many industrial applications. The True RMS capability is essential for accurate measurements on variable frequency drives common in three-phase systems. The Fluke 323’s CAT IV 300V rating makes it suitable for measurements on the primary supply side. However, for very high-voltage three-phase systems, always verify that the meter’s voltage and category ratings exceed the system’s potential.
What type of batteries do these meters use, and are they included?
The Fluke 117 typically uses a 9V battery, and the Fluke 323 uses AA batteries. Most Fluke meters do not include batteries in the box, as shipping regulations restrict lithium batteries. You will need to purchase common alkaline or lithium batteries separately. The instruction manual provides specific battery requirements and installation instructions.
