Frequently Asked Questions - BM235 Brymen
What is the maximum voltage the BM235 can measure?
The BM235 can measure up to 600 V in both AC and DC modes. It is rated CAT III 600V and CAT IV 300V for safety.
Does the Brymen BM235 have True RMS measurement?
Yes, the BM235 features True RMS AC coupled measurement, allowing accurate readings on non-sinusoidal waveforms.
What is the LoZ (Low Impedance) function used for?
The LoZ function helps eliminate ghost voltages by placing a low impedance load on the circuit, ensuring you measure only real voltages. It is ideal for troubleshooting in industrial environments.
Can the BM235 measure temperature?
Yes, with an optional K-type thermocouple (not included), it can measure temperature from -40°C to 1000°C (-40°F to 1832°F).
How do I replace the battery in the BM235?
Turn off the meter and remove the test leads. Use a screwdriver to remove the battery compartment screw on the back. Replace the 9V battery (NEDA 1604 or 6F22) and reattach the cover.
What safety features does the BM235 have?
It has overload protection on all ranges, a high-energy fuse on the 10A input, and meets IEC 61010-1 standards for CAT III 600V and CAT IV 300V.
Does the BM235 have a backlight?
Yes, it has a white LED backlight that automatically turns off after a short period to save battery. It can be activated by pressing the backlight button.
What is the accuracy of the BM235?
DC voltage accuracy is ±0.5% + 3 digits. AC voltage accuracy is ±1.0% + 5 digits (50-60 Hz). Other ranges have similar or better specifications.
How do I use the data hold function?
Press the HOLD button to freeze the current reading on the display. This is useful for capturing measurements in hard-to-see locations.
What accessories are included with the BM235?
The multimeter typically includes test leads, a 9V battery, a user manual, and sometimes a K-type thermocouple adapter. Check your package for specifics.
