Troubleshooting Common Issues
Issue #1: Display Shows “OL” or No Reading
Problem: The multimeter displays “OL” (Over Limit) or shows no value when trying to measure voltage or resistance.
Solution: First, verify you’ve selected the correct function on the rotary dial (e.g., DC Voltage for a battery). Ensure the test leads are firmly plugged into the correct jacks (COM and VΞ©mA). For resistance, make sure the component is not connected to any power source.
Prevention: Always double-check your function selection and lead placement before taking a measurement.
Issue #2: Inaccurate or Fluctuating Readings
Problem: Voltage or resistance readings jump around or seem inconsistent with expected values.
Solution: Check the health of the included 9V battery; a weak battery can cause erratic behavior. Ensure test lead probes are making solid contact with clean metal surfaces. For DC measurements, verify you have the red lead on positive and black on negative.
Tech Note: The 2000-count resolution provides more precise digits, so minor fluctuations on the last digit are normal.
Issue #3: Continuity Buzzer Not Sounding
Problem: The audible continuity buzzer does not sound when the probes are touched together, even in the continuity function.
Solution:
- Confirm the meter is set to the continuity symbol (diode symbol with sound waves).
- Check that the test leads are not damaged; try touching the metal tips of the leads directly together.
- Use the data hold function to freeze the display and see if a resistance value near 0.0Ξ© appears, which indicates continuity even without sound.
Issue #4: Backlit LCD Display is Dim or Off
Problem: The backlight does not turn on, making the screen hard to read in low light.
Solution: The backlight may have an auto-off feature to conserve the 9V battery. Consult the user manual for the specific button press or mode to activate it. If it still doesn’t work, replace the 9V battery, as a low battery often disables power-intensive features like the backlight first.
Safety Feature: The overload protection will not affect the display backlight function.
Issue #5: Meter Shows Strange Symbols or Resets
Problem: The display shows unfamiliar icons or the meter resets itself during use.
Solution: This is typically a sign of a nearly depleted 9V battery. Replace it with a fresh one immediately. Also, ensure you are not exceeding the meter’s measurement limits, as this could trigger protective functions. The compact design houses all electronics, so physical damage from a drop could cause this.

Frequently Asked Questions
What does “2000 Counts” mean for a multimeter?
This refers to the display’s resolution, not the maximum value it can measure. A 2000-count meter can display up to 1999 on its screen before rolling over. For example, on the 20V DC range, it can show values from 0.001V to 19.99V with three digits of precision. This provides more detailed readings than a basic 600-count meter, which would only show up to 5.99V on the same range.
Can I measure AC current with this multimeter?
No, the LJPXHHU is specifically listed as measuring DC Current only. The keyword specifies “Measures AC/DC Voltage, DC Current…” This means it can measure both types of voltage but only direct current (DC) for current. To measure AC current (like household appliance draw), you would need a clamp meter or a multimeter with AC current capability.
Is the 9V battery included, and how long does it last?
Yes, a 9V battery is included in the box, making the meter ready to use immediately. Battery life depends heavily on usage frequency, especially use of the backlit LCD display. With moderate use (a few hours per week), the included battery should last several months. The compact design makes battery replacement straightforward when needed.
What is the “Data Hold” function used for?
The Data Hold function freezes the current reading on the backlit LCD display. This is invaluable when you’re probing a circuit in a tight space and can’t look directly at the meter, or when you need to record a measurement. You press the button to capture the value, then you can safely look away to write it down or analyze the result without losing the reading.
What kind of overload protection does it have?
The keyword mentions “Overload Protection” as a key safety feature. This typically means the meter has internal fuses or circuits designed to protect it from damage if you accidentally connect it to a voltage or current beyond its rated capacity. For instance, if you select the resistance function but probe a live circuit, the protection helps prevent permanent damage to the meter’s internal components.
Can I test a car battery’s health accurately with this?
Yes, the ability to measure DC Voltage makes it suitable for basic car battery testing. You can check the resting voltage (should be ~12.6V for a charged battery) and the voltage while cranking (should not drop below ~10V). For a more comprehensive battery health test including cold cranking amps (CCA), you would need a dedicated battery load tester, but this meter provides excellent initial diagnostics.
