Frequently Asked Questions - MBX300 MTM
How do I measure DC voltage with the MBX300?
Turn the rotary dial to the V DC position. Connect the black lead to COM and red lead to V/Ω. Touch the probes to the test points and read the display.
What does 'OL' mean on the display?
'OL' stands for Over Limit. It indicates that the measured value exceeds the selected range or the meter's maximum capacity. Switch to a higher range if possible.
How do I replace the battery?
Remove the screw on the back cover, slide off the battery compartment, replace the 9V battery with a new one of the same type, and reattach the cover.
Can I measure AC current with this multimeter?
Yes. Turn the dial to A AC (or mA AC for small currents). Connect the red lead to the 10A or mA/μA jack as appropriate, and break the circuit to insert the meter in series.
What is the continuity test function?
The continuity test checks if a circuit is complete. Turn the dial to the continuity symbol (looks like a diode with sound waves). The meter will beep if the resistance is below about 30 Ω.
How accurate is the MBX300?
Basic DC voltage accuracy is typically ±(0.5% + 5 digits). Refer to the manual for full specifications. Accuracy may vary by range and environment.
What safety precautions should I take?
Always use the correct input jacks and range. Do not measure voltages above 600V AC/DC relative to earth. Inspect test leads for damage before use. Remove test leads before opening the battery cover.
Does the MBX300 have auto-ranging?
Yes, it supports auto-ranging for most functions. You can also manually select a range using the RANGE button.
How do I use the data hold feature?
Press the HOLD button to freeze the current reading on the display. Press again to release.
Where can I find replacement test leads?
Replacement test leads can be purchased from electronics suppliers. Ensure they are rated for CAT II 600V or higher. Use only leads with shrouded banana plugs.
