    Function Selection:
    Frequency and Rotate speed display Set
    (Please d
    isconnect the input signal
    before setting when the input signal is
    High level voltage signal)
    Open the back cover
    of the meter, you will find two keys switch " S1" and "S2"
    Press
    "
    S2
    " key to enter "SET" model and then press "S1" to change display mode
    ,
    "0"
    means
    Frequency display
    with filter ;
    "1"
    means
    rotate speed
    with
    filter;
    "2
    "
    means
    Frequency display
    without filter ;
    "3"
    means
    rotate speed
    without

    Divider
    concept
    :
    The number of the singal the
    gears get for one circle
    .
    For example
    ,
    a
    gear
    can take
    20
    pulse signal
    for one circle ,
    the
    divider
    value
    could be
    set to
    20.
    High and Low voltage
    signal input
    switch
    (
    Please d
    isconnect the input signal
    before setting when the input signal is
    High level voltage signal)
    The
    default set for this meter is
    the
    low voltage input
    ,
    if you need
    high-voltage input
    ,
    you
    need
    to
    open  the back cover
    the more the short jumer from the "L
    "
    part.
    Enter
    the
    high voltage directly
    will
    damage
    the
    meter
    if the
    short jumper is not removed.
    We are not responsibility for this damage. Please
    carefully
