Instruments’
A. Dual-channel capability permits simultaneous measurements of amplitude
and phase at two locations.
B. Digital display readout in engineering units eliminates the need to convert
volts to displacement units or to double integrate acceleration signals.
C. A peak-to-peak display mode allows the MTI-2000 to be used as a self-
contained vibration measurement tool.
D. An easy-to-read
bargraph
display simplifies setup and gives an “analog feel”
to the instrument.
E. An out-of-range indicator notifies the user if a probe moves out of preset
range, preventing measurement error.
F. Pushbutton operation simplifies the calibration of fiber-optic probes.
G. Interchangeable probe modules allow the user to select from seven standard
fiber-optic probe designs for the sensitivity, range and frequency response they
need. Custom modules can be supplied to meet specific frequency response or
gain requirements.
