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.

Distorted waveforms with the presence of DC components and harmonics may cause: Always set the instrument to the highest range and work downward for an unknown value when using manual ranging mode.

In other words, the meter will intelligently avoid entering the APO mode when it is under normal measurements. Do not attempt a current measurement to any circuit where the open circuit voltage is above the protection fuse voltage rating.
Auto Power Off feature will be disabled automatically in this mode. It can also brumen loaded way beyond seconds at 1A, and has a fast acting characteristic of below 0. Reverse the test leads connections reverse bryjen across the diode. If any defects are found, replace them immediately. Keep your fingers behind the finger guards of the test leads during measurement. This protection characteristic also matches our meter nicely.
Lift the battery access door and thus the battery compartment up. Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents.
The new impedance value will be saved automatically to the non-volatile memory as power up default. Per IEC 2nd Ed.
Battery replacement for models with battery access door: In voltage or current functions, press the Hz push button momentarily to activate or to exit Line Level Frequency measuring function.
The series fusible resistors and the spark gaps should then be replaced by qualified technician. Press the button momentarily again to step through the ranges. Dual brjmen T1-T2 readings require 2 probes. In reality, complex waveforms, noise and distorted waveforms contain much higher frequency spectrum than its fundamental. Loosen the 2 screws from the battery access door of the case bottom. 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 Activities are specified as: Manual ranging mode feature is not available in Hz function.
Any other readings indicate the diode is resistive or shorted defective. The meter beeps when new maximum or minimum reading is updated.
Relative Zero mode Relative Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. Only replace the bm859cv fuse with the proper rating as specified in this manual. It will also be turned off automatically after 30 seconds to extend battery life.
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. The analog bargraph pointer will point at the selected trigger level range scale 1, 2, 3, or 4. That is, mV function has the highest bm89cf the V range has the lowest as in voltage function ranges.

In measuring pure sinusoidal waveform, this technique is fast, accurate, and cost effective. Continuity function is convenient for checking wiring connections and operation of switches. The new setting will be saved automatically to the non-volatile memory as power up default. These voltage levels pose a potential shock hazard to the user.
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. 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. If the instrument voltage-resistance input terminal bm859ccf subjected to high voltage transient caused by lightning or switching surge to the system by accident or abnormal hrymen of operation, the series fusible resistors will be blown off become high impedance like fuses to protect the user and the instrument.
Note — Examples include electricity meters and primary over-current protection equipment. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired.
This technique is to obtain the average value by rectifying and filtering the AC signal.

Suspected open circuit voltage should be checked with voltage functions. The digital display shows OL if the diode is good. Install only the same type of fuse or equivalent Trouble Shooting If the instrument fails to operate, check battery, fuses, leads, etc. 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.
Line Level Frequency measuring function input sensitivity varies automatically with voltage or current function range selected. Inspect test leads, connectors, and probes for damaged insulation or exposed metal before using the instrument.
The average value is then scaled upward calibrated to read the RMS value of a sine wave. Press and hold the button for 1 second or more to resume auto-ranging mode. 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.
If the meter is not to be used for periods of longer than 60 days, remove the battery and store it separately.
