Frequently Asked Questions - BM252s Brymen
How do I measure DC voltage with the BM252s?
Turn the rotary switch to the DC voltage range (Vdc). Connect the black test lead to COM and red to VΩ. Probe the circuit and read the display. For higher accuracy, use auto-ranging.
What safety precautions should I take?
Always observe the CAT III 1000V rating. Use proper test leads, inspect for damage, and never exceed the rated voltage. Disconnect power before measuring resistance or continuity.
How do I replace the battery?
Remove the tilt stand and unscrew the battery compartment. Replace the 9V battery (NEDA 1604A) with a new one, observing polarity. Reattach the cover.
Can I measure AC current with this multimeter?
Yes, turn the rotary switch to the AC current range (Aac). For currents up to 10A, connect the red lead to the 10A input jack. For smaller currents, use the mA/µA jack. Always select the correct range.
What is the purpose of the HOLD button?
The HOLD button freezes the current reading on the display, allowing you to record measurements in hard-to-see places. Press again to release.
How do I measure temperature?
Connect a type K thermocouple to the COM and VΩ inputs (using an adapter if needed). Set the rotary switch to the temperature range. The display shows the temperature in °C or °F, depending on setting.
What does the continuity test do?
The continuity test produces a beep when the resistance between probes is less than a threshold (typically 50Ω). It is useful for checking fuses, wires, and circuit paths. Ensure the circuit is de-energized before testing.
How do I clean the BM252s?
Turn off the meter and remove leads. Wipe the casing with a damp cloth. Do not use abrasives or solvents. Keep the input jacks clean and dry.
Why does the display show 'OL'?
OL stands for Overload or Open Loop. It indicates the measurement exceeds the selected range, or the circuit is open. Switch to a higher range or check connections.
Can I measure capacitors with the BM252s?
Yes, set the rotary switch to the capacitance range. Discharge the capacitor fully before connecting it to the test leads. The meter will display the capacitance value after a few seconds.
