Troubleshooting Common Issues
Issue #1: Display Shows “OL” or No Reading
Problem: The 3½-digit backlit LCD displays “OL” (Overload) or shows no value when testing a known live circuit or component.
Solution: First, ensure the rotary dial is set to the correct function (e.g., V~ for AC voltage, V⎓ for DC). Check that the test leads are firmly plugged into the correct jacks (COM and VΩmA). The overload protection feature may be active if the input exceeds the selected range.
Prevention: Always start with the highest range setting and work down for unknown values.
Issue #2: No Sound from Continuity Buzzer
Problem: The audible continuity buzzer doesn’t beep when touching the test leads together, even when the dial is set to the continuity symbol.
Solution: Verify the dial is correctly set to the continuity/diode position. Check the 9V battery included with the unit; a weak battery can cause buzzer failure. Ensure the test leads are making good contact—try using the included alligator clips for a more secure connection.
Tech Note: The buzzer only sounds when resistance is very low (typically <50Ω), indicating a complete circuit.
Issue #3: Inaccurate or Fluctuating Readings
Problem: Measurements seem wrong or the numbers on the 1999 count display jump around erratically.
Solution:
- Use the Data Hold function to freeze a stable reading.
- Check for poor probe contact; corroded or dirty test lead tips can cause resistance.
- Ensure you’re not testing near strong magnetic fields or other interference sources.
Issue #4: Backlit LCD Display is Dim or Off
Problem: The backlit LCD display is too dim to read or won’t turn on in low light.
Solution: This is almost always a battery issue. Replace the 9V battery. The included battery is for initial use but may not be a long-life type. Confirm the meter is powered on (dial turned from OFF position).
Safety Feature: A dim display is the meter’s way of indicating low power before complete failure.
Issue #5: Meter Won’t Power On
Problem: The multimeter shows no signs of life when the dial is turned from OFF.
Solution: Replace the 9V battery. Ensure the battery contacts inside the compartment are clean and making connection. Inspect the fuse (if accessible) related to the function you were using when it stopped working, though the overload protection is designed to prevent fuse blows from common errors.
