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.

Keep your fingers behind the finger guards of the test leads during measurement. In many cases the suspected component must be disconnected from the brymeb to obtain an accurate reading.


It will also be turned off automatically after 30 seconds to extend battery life. To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. However, if BRYMEN determines that the failure was caused by misused, altered, neglected, or damaged by accident or abnormal conditions of operation or handling, you will be billed for the repair. Line Level Frequency measuring function is designed especially for noisy electrical high voltage signals.

Distorted waveforms with the presence of DC components and harmonics may cause: Only replace the blown fuse with the proper rating as specified in this manual.

If the meter is not to be used for periods of longer than 60 days, remove the battery and store it separately. This technique is to obtain the average value by rectifying and filtering the AC signal. Per IEC 2nd Ed. However, the continuity and Jack Beep input warning features remain.


If the reading shows zero, select higher sensitivity. In measuring non-sinusoidal waveforms, however, significant errors can be introduced because of different scaling factors relating average to RMS values. Loosen the 4 screws from the case bottom. NMRR nm859cf typically specified in terms of dB decibel.

In other words, the meter will intelligently avoid entering the APO mode when it is under normal measurements. If the instrument voltage-resistance input terminal has subjected to high voltage transient 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. It is excellent in detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments.

You can also use a plug adapter Bkb32 Optional purchase with banana pins to K-type socket to adapt other standard K type mini plug temperature probes. These voltage levels pose a potential shock hazard to the user.

CMRR is the DMM’s ability to reject common mode voltage effect that can cause digit rattle or offset in voltage measurements. It is not the frequency measurement function, and is the frequency response of the AC functions. Unlike the Line Level Frequency measuring function as previously stated, this Logic Level Frequency function is set only at the highest input sensitivity to measure digital type electronic signals.

In reality, complex waveforms, noise and distorted waveforms contain much higher frequency spectrum than its fundamental. Any other readings indicate the diode is resistive or shorted defective.


Press and hold the button for 1 second or more to resume auto-ranging mode. Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle.

Most measuring functions through this terminal will then be open circuit. Lift the end of the case bottom nearest the input jacks until it unsnaps from the case top. A continuous beep tone indicates a complete wire.

The new impedance value will be saved automatically to the non-volatile memory as power up default. Auto Power Off feature will be disabled bm859cff in this mode. This protection characteristic also matches our meter nicely. In voltage or current functions, press the Hz push button momentarily to activate or to exit Line Level Frequency measuring function. Press the button momentarily to bm859cg and to exit Relative Zero mode.

A zero reading indicates a shorted diode defective. The new settings will be saved automatically to the non-volatile memory as power up default. However, DC component plays an important role in the distorted non-symmetrical waveforms, and will also be of interest sometimes.

In dBm function, power up default reference impedance will be displayed for 1 second before displaying the dBm readings. Reverse the test bm59cf connections reverse biased across the diode.
