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.

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.
The new settings 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. Do not measure any current that exceeds the current rating of the protection fuse.

It will also be turned off automatically after 30 seconds to extend battery life. However, DC component plays an important role in the distorted non-symmetrical waveforms, and will also be of interest sometimes.
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.
Always turn the rotary switch to the OFF position when the meter is not in use. It’s a community-based project which helps to repair anything. 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.

Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents.
CMRR is the DMM’s ability to reject common mode voltage effect that can cause digit rattle or offset in voltage measurements. Loosen the 4 screws from the case bottom. In measuring non-sinusoidal waveforms, however, significant errors can be introduced because of different scaling factors relating average to RMS values.

Relative Zero mode Relative Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. Reverse the test leads connections reverse biased across the diode. An OL indicates an open diode defective. Press the button momentarily to activate and grymen exit Relative Zero mode.
Note — Examples include household, office, and laboratory appliances. A reading higher than that indicates a leaky diode defective. If the meter is not to be used for periods of longer than 60 days, remove the battery and store it separately.
If the Hz reading is unstable, select lower sensitivity to avoid electrical noise. Refer to the explanation in this Manual! Note — Examples include electricity meters and primary over-current protection equipment. The digital display shows OL if the diode is good.
This technique is to obtain the average value by rectifying and filtering the AC signal. In dBm function, power up default reference impedance will be displayed for 1 second before displaying the dBm readings.
This protection characteristic also matches our meter nicely. Battery replacement for models with battery access door: It is not the frequency measurement function, and is the frequency response of the AC functions. Do not attempt a current measurement to any circuit where the open circuit voltage is above the protection fuse voltage rating.
Inspect test leads, connectors, and probes for damaged insulation or bk859cf metal before using the instrument. The meter is intended only for indoor use.
Any other readings indicate the diode is resistive or shorted defective. The series fusible resistors and the spark gaps should then be replaced by qualified technician. Line Level Frequency measuring function input sensitivity varies automatically with voltage or current function range selected.
