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 However, DC component plays an important role in the distorted non-symmetrical waveforms, and brymem also be of interest sometimes. In voltage or current functions, press the Hz push button momentarily to activate or to exit Line Level Frequency measuring function.

Suspected open circuit voltage should be checked with voltage functions. Line Level Frequency measuring function is designed especially for noisy electrical high voltage signals. 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.

Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. Do not touch test lead tips or the circuit bm859vf tested while power is applied to the circuit being measured. Most measuring functions through this terminal will then be open circuit. The digital display shows OL if the diode is gm859cf.

Manual ranging mode feature is not available in Hz function. Insert the banana plug K-type temperature bead probe Bkp60 standard accessory x 1 with correct polarities. If any defects are found, replace them immediately. When measuring a 3-phase system, special attention should be taken to the phase to phase voltage which is significantly higher than the phase to earth voltage.


BM857 BM859CF

A reading higher than that indicates a leaky diode defective. Note — Examples include household, office, and laboratory appliances.

If the Hz reading is unstable, select lower sensitivity to avoid electrical noise. The series fusible resistors and the spark gaps should then be replaced by qualified technician. Replace b8m59cf case bottom, and ensure that all the gaskets are properly seated and the bryken snaps on the case top near the LCD side are engaged.

The new impedance value will be saved automatically to the non-volatile memory as power up default. The bm859cc the measuring range the higher the sensitivity. 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.

A continuous beep tone indicates a complete wire. In many cases the suspected component must be disconnected from the circuit to obtain an accurate reading. Note — Examples include switches in the fixed installation and some equipment for industrial use with permanent connection to the fixed installation.

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. Relative Zero mode Relative Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value.

Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. This technique is to obtain the average value by rectifying and filtering the AC signal.

Always turn the rotary switch to the OFF position when the meter is not in use. Keep your fingers behind the finger guards of the test leads during measurement. To avoid exceeding the voltage rating of the protection fuse s accidentally, always consider the phase to phase voltage as the working voltage for the protection fuse s.


An OL indicates an bm859cg diode defective. Any other readings indicate the diode is resistive or shorted defective. Auto Power Off feature will be disabled automatically in this mode. The new settings will be saved automatically to brymeen non-volatile memory as power up default.

The meter beeps when new maximum or minimum reading is updated. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired.

RSC PC computer interface capabilities The instrument equips with an optical isolated interface port at the meter back for data communication. 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 bm89cf like fuses to protect the user and the instrument.

Refer to the explanation in this Manual! Always set the instrument to the highest range and work downward for an unknown value when using manual ranging mode. In reality, complex waveforms, noise and distorted waveforms contain much higher frequency spectrum than its fundamental.

That is, mV function has the highest and the V range has the lowest as in voltage function ranges.

It will also be turned off automatically after 30 seconds to extend battery life. It’s a community-based project which helps to repair anything. 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.
