Frequently Asked Questions - NF-5310B Noyafa
How do I measure AC voltage with the NF-5310B?
Set the rotary switch to the AC voltage range (200V or 600V). Insert the black lead into COM and red lead into VΩmA. Connect the probes to the circuit. Read the display.
What does the 'OL' reading mean?
OL indicates overload or the measured value exceeds the selected range. Switch to a higher range if possible.
How do I replace the battery?
Turn off the meter and remove the test leads. Unscrew the battery cover screw, slide off the cover, replace the old 9V battery with a new one, and reattach the cover.
Can I measure current without disconnecting the circuit?
No, you must break the circuit and connect the meter in series. For currents up to 200mA, use the mA jack; for up to 10A, use the 10A jack.
What is the continuity test and how do I use it?
The continuity test verifies if a circuit is complete. Set the dial to the continuity symbol (like a sound wave). Connect probes to the circuit; an audible beep indicates continuity (<50Ω).
Why does the display show a low battery symbol?
The battery voltage is low and should be replaced soon. Replace with a fresh 9V battery to ensure accurate measurements.
What safety precautions should I take?
Always use the correct range and jacks. Do not exceed the maximum rated voltage (600V). Inspect test leads for damage. Do not use in wet conditions.
Can I measure capacitance with this multimeter?
Yes, set the dial to the capacitance mode (F). Insert the capacitor into the dedicated input jack and read the value. Ensure the capacitor is discharged before testing.
How do I use the data hold function?
Press the DATA HOLD button to freeze the current reading on the display. Press it again to release. Useful for recording measurements in hard-to-see locations.
What is the auto power off feature?
The meter automatically turns off after about 15 minutes of inactivity to save battery. To wake it, rotate the function switch or press any button.
