BRYMEN’s warranty does not apply to accessories, fuses, fusible resistors, spark gaps, batteries or any product which, in BRYMEN’s opinion, has been misused, altered, neglected, or damaged by accident or abnormal conditions of operation or handling. The average value is then scaled upward calibrated to read the RMS value of a sine wave.

This protection characteristic also matches our meter nicely. It will also be turned off automatically after 30 seconds to extend battery life. Do not attempt a current measurement to any circuit where the open circuit voltage is above the protection fuse voltage rating. To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms.

Insert the banana plug K-type temperature bead probe Bkp60 standard accessory x 1 with correct polarities. However, if BRYMEN determines that the failure was caused brymne misused, altered, neglected, or damaged by accident or abnormal conditions of operation or handling, you will be billed for the repair. Replace the case bottom, and brymeh that all the gaskets are properly seated and the two snaps on the case top near the LCD side are engaged.


NMRR is typically specified in terms of dB decibel. In dBm function, power up default reference impedance will be displayed for 1 second before displaying the dBm readings.

Press and hold the button for 1 second or more to resume auto-ranging mode. That is, mV function has the highest and the V range has the lowest as in voltage function ranges. However, the continuity and Jack Beep input warning features remain. Most measuring functions through this terminal will then be open circuit.

It can also be loaded way beyond seconds at 1A, and has a fast acting characteristic of below 0.

Continuity function is convenient for checking wiring connections and operation of switches. An OL indicates an open diode defective.


Relative Zero mode B859cf Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. Press the button momentarily again to step through the ranges. It is excellent in detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments. The analog bargraph pointer will point at the selected trigger level range scale 1, 2, 3, or 4.

Press button momentarily to toggle between 5 bj859cf digits and 6 full digits Hz readings. Always set the instrument to the highest range and work downward for an unknown value when using manual ranging mode. Suspected open circuit voltage should be checked with voltage functions.



Line Level Frequency measuring function is designed especially for noisy electrical high voltage signals. Any other readings indicate the diode is resistive or shorted defective.

If any defects are found, replace them immediately.

Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not bm859xf abrasives or solvents. CMRR is the DMM’s ability to reject common mode voltage effect that can cause digit rattle or offset in voltage measurements.

Keep your fingers behind the finger guards of the test leads during measurement. In voltage brymenn current functions, press the Hz push button momentarily to activate or to exit Line Level Frequency measuring function. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may bbrymen impaired.

Do not operate with open case. Manual ranging mode feature is not available in Hz function. Large value capacitors should be discharged through an appropriate resistance load. The lower the measuring range the higher the sensitivity.
