BMs – Top class digital multimeter made by Brymen. counts (5 4/5 digit), High Performance, User-oriented innovative features. Unbeatable 1µV. USER’S MANUAL BM BMCF 1 1) SAFETY This manual contains .. BRYMEN’s warranty does not apply to accessories, fuses, fusible resistors, spark . Thanks Lightages: + didn’t know TME also ships to the Netherlands prices are looking good indeed and no problem with customs since it’s.

However, the continuity and Jack Beep input warning features remain. Always set the instrument to the highest range and work downward for an unknown value when using manual ranging mode. Inspect test leads, connectors, and probes for damaged insulation or exposed metal before using the instrument.

Do not measure any current that exceeds the current rating of the protection fuse. Refer to the explanation in this Manual! Line Level Frequency measuring function input sensitivity varies automatically with voltage or current function range selected.

A full wave rectified sine waveform is a good example, and the AC true RMS function will only give the AC component reading which is at That is, mV function has the highest and the V range has the lowest as in voltage function ranges.

Install only the same type of fuse or equivalent Trouble Shooting If the instrument fails to operate, check battery, fuses, leads, etc. Suspected open circuit voltage should be checked with voltage functions.

The digital display shows OL if the diode is good. The meter is intended only for indoor use. Press the button momentarily to activate and to exit Relative Zero mode. Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents.



Press the HOLD momentarily to activate or to exit the hold function. Manual ranging mode feature is not available in Hz function. The new setting will be saved automatically to the non-volatile memory as power up default.

Lift the end of the case bottom nearest the input jacks until it unsnaps from bryemn case top.

Most measuring functions through this terminal will then be open circuit. In other words, the meter will intelligently avoid entering the APO mode when it is under normal measurements.

Do not operate with open case. If the meter is not to be used for periods of longer than 60 days, remove the battery and store it separately. If the instrument voltage-resistance input terminal has subjected to high voltage brymn caused by lightning or switching surge to the system by accident or abnormal conditions of operation, the series fusible resistors will be blown off become high impedance like fuses to protect the user and the instrument.

Large value capacitors should be discharged through an appropriate resistance load.

When activated from voltage function, you can brymsn press the RANGE button momentarily to select another trigger level range manually. A reading higher than that indicates a leaky diode defective. However, DC component plays an important role in the distorted non-symmetrical waveforms, and will also be of interest sometimes.

Note — Examples include household, office, and laboratory appliances. Any bm589cf readings indicate the diode is resistive or shorted defective. The lower the measuring range the higher the sensitivity. The new impedance value will be saved automatically to the non-volatile memory as power up default.

Line Level Frequency measuring function is designed especially for noisy electrical high voltage signals. Per IEC 2nd Ed. Activities are specified as: 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.


In reality, complex waveforms, noise and distorted waveforms contain much higher frequency spectrum than its fundamental. These voltage levels pose a potential shock hazard btymen the user. It is excellent in detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments.

Brymen BM859CF Manuals

It is recommended to first measure the signal voltage or current level then activate the Hz function in that voltage or current range to automatically get the most appropriate trigger level.

Only replace the blown fuse with the proper rating as specified in this manual. In dBm function, power up default bm859cd impedance will be displayed for 1 second before displaying the dBm readings. To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms.

You can also use a plug adapter Bkb32 Optional purchase with banana bm859f to K-type socket to adapt other standard K type mini plug temperature probes. Brymej your fingers behind the finger guards of the brjmen leads during measurement. Do not touch test lead tips or the circuit being tested while power is applied to the circuit being measured. Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle.

Note — Examples include electricity meters and primary over-current protection equipment. Distorted waveforms with the presence of DC components and harmonics may cause: The new settings will be saved automatically to the non-volatile memory as power up default.
