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.

The new settings will be saved automatically to bm859f non-volatile memory as power up default. Any other readings indicate the diode is resistive or shorted defective.


Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. Continuity function is convenient for checking wiring connections and operation of switches.

CMRR is the DMM’s ability to reject common mode voltage effect that can cause digit rattle or offset in voltage measurements. Press the HOLD momentarily to activate or to exit the hold function. The new setting will be saved automatically to the non-volatile memory as power up default. In reality, complex waveforms, noise and distorted waveforms contain bm859ct higher frequency spectrum than its fundamental.

Press the button momentarily bm859f activate and to exit Relative Zero mode. Do not attempt a current measurement to any circuit where the open circuit voltage is above the protection fuse voltage rating.

If any defects are found, replace them immediately. Reverse the test leads connections reverse biased across the diode. Relative Zero mode Relative Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value.


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. Press and hold the button for 1 second or more to resume auto-ranging mode.

RSC PC computer interface capabilities The instrument equips with an optical isolated interface port at the meter back for data communication. If the Hz reading is unstable, select lower sensitivity to avoid electrical noise. However, the continuity and Jack Beep input warning features remain. However, DC component plays an important role in the distorted non-symmetrical waveforms, and will also be of interest sometimes. A continuous beep tone indicates a complete wire.

Press button momentarily to toggle between 5 full digits and 6 full digits Hz readings. The meter beeps when new maximum or minimum reading is updated. In other words, the meter will intelligently avoid entering the APO mode when it is under normal measurements.

Do not operate with open case. Fuse replacement and also Battery replacement for splash proof version without battery access door: Note — Examples include switches in the fixed installation and some equipment for industrial use with permanent connection to the fixed installation.

Most measuring functions through this terminal will then be open circuit. This technique is to obtain the average value by rectifying and filtering the AC signal. Line Level Frequency measuring function is designed especially for noisy electrical high voltage signals. Replace the case bottom, and ensure that all the gaskets are properly seated and the two snaps on the case top near the LCD side are engaged.


The analog bar-graph remains the mA current value to alert the user. Large value capacitors should be discharged through an appropriate resistance load.

If the instrument voltage-resistance input terminal has subjected to high voltage transient caused by lightning or mb859cf surge to the system by accident or abnormal conditions of operation, the series brumen resistors will be blown off become high impedance like fuses to protect the user and the instrument. Only replace the blown fuse with the proper rating as specified in this manual. 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.

Brymen BM859CF Manuals

If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired. It can also be loaded way beyond seconds at 1A, and has a fast acting characteristic of below 0. Refer to the explanation in this Manual! Lift the end of the case bottom nearest the input jacks until it unsnaps from the case top. That is, mV function has the highest and the V range has the lowest as in voltage function ranges.

Note — Examples include household, office, and laboratory appliances. Auto Power Off feature will be bm895cf automatically in this mode.
