LFM 1010  Low frequency Electrical/magnetic field monitor

    The LFM1010 electric and magnetic fields meter allows to measure and analyze easily and
    accurately low frequency fields generated by appliances and power lines. Its wide frequency
    range from 10 Hz to 100 kHz covers interferences generated directly from the 50/60Hz mains
    network and its harmonics, but also the higher frequency signals generated by switching power
    supplies, devices with microprocessors or low energy light bulbs.
    Portable and ergonomic thanks to many innovative features, it can quickly diagnose the sources
    of disturbances and help to provide solutions.
    This device will find wide scope to the equipment engineer wishing to verify the level of
    interference emitted by them, as well as in the individual concerned to verify the quality of their
    home or place of work. It will be very helpful to determine the influence of a power line or to
    optimize the wiring of an electrical installation.

    Alarm Mode:
    It is possible to set an alarm threshold at a given
    level of electrical or magnetic fields, beyond which
    the device will beep. This alarm mode can remain
    active even with the device in standby mode
    (display off), allowing greater autonomy. It is thus
    possible to detect levels of field emitted
    intermittently, or by leaving the device at a given
    location, to test different configurations or to enable
    different devices to determine those likely to
    generate fields above a threshold.
    The LFM1010 can have an autonomy of 1000h in
    standby mode with alarm mode active.

    Switchable filter:
    A low pass filter cutoff frequency of 1 kHz can be
    activated to limit the scope of exploration at very low
    frequencies (eg mains network) and not be
    disturbed by the signals at higher frequencies
    generated by switching power supplies and energy
    saving bulbs for example.

    Dosimeter mode:
    This method integrates the measurements over a
    prolonged period, even with the device in standby
    mode, to determine the amount of electric and
    magnetic radiation received by unit (and thus by the
    wearer) over the same period in his daily trip.
