    This section shows how to verify that the system is operating properly, adjust the
    system, and identify parts of the system that are not working properly.
    The transmitter system does not require verification at regular intervals. You should,
    however, verify operation by using the scale factor verification on page 10 if any of the
    following conditions occur:
    ! components of the system are replaced or disturbed
    ! the performance of the system changes or becomes erratic
    ! you suspect that the transmitter is not calibrated correctly
    The adjustment procedures on pages 11 thru 16 are included for your information. For
    target materials other than 4140 steel and for other special applications, contact your
    local Bently Nevada office.
    The scale factor verification procedure, the scale factor adjustment procedure, and the
    zero/span adjustment procedure require the following instruments:
    digital multimeter (2)
    spindle micrometer
    power supply
