The ENDEVCO Model 4830A is a battery operated instrument that is used to electronically simulate a
variety of outputs from vibration transducers. Also provided is a tachometer output that provides a TTL level
output signal. The output signals can be set-up in actual pC or millvolts. All parameters are entered via a
front panel key pad that is sealed per IP65.
The following simulated sensor outputs are available from the Portable Simulator:
• Acceleration
• Displacement
• Velocity
• Tachometer
Output signals are provided that simulate voltage mode accelerometers (IEPE, ISOTRON, etc) and charge
mode accelerometers, both single-ended and differential types. While the 4830A provides an accurate and
repeatable signal, it is not a substitute for the manufactures recommended calibration intervals.
All units are provided with a padded carrying case, charger, snap-on filter for the battery charger and a
twinax BNC connector. Optional cables are available from Meggitt Sensing Systems. Please contact the
factory or your local representative/reseller for further information.
This manual covers the basic operation on the 4830A along with a section on servicing and calibration.
