Operating Description
System Version
3.0 CORRECTED: When setting the following parameters OffRoute and applying a 60 Hz sine wave at 100 mV Pk with a -1V DC offset:
• Accel (g), DC Coupling, Peak Detection, Filter OFF, 400 Hz Fmax
You will get these results:
• Overall - 23.1 g
• 0 Hz bin - 20.1 g
• 60 Hz bin - 1 g
CORRECTED: Orders-based measurements collect as if the Fmax is based on the speed downloaded from the Emonitor software, so changing the actual speed
does not change the Fmax used for the measurement.
CORRECTED: Measurements are collected with the wrong Fmax for Orders points with speed set by a Control Point. If a point is set up as Orders but with the
speed coming from a Control Point, then (in many cases) the measurement is taken with the incorrect Fmax that makes the frequencies labeled incorrectly.
CORRECTED: Downloading a route where the first point is unsupported and can give TourDB errors even though the invalid point is not downloaded and
require a soft restart.
CORRECTED: If there is a point with a Magnitude and Spectrum collection, and you are using an Analog Filter, then it is possible for the Spectrum Peak to be
much larger than the Overall - especially if the measurement is Integrated.
2.0 CORRECTED: The WinserDL download utility program did not correctly store the memory address labels in the registry.
CORRECTED: Intermittently the Enpac 2500 did not recognize the memory card.
CORRECTED: The data collector did not store the orbit measurements when the number of lines in the collection specification was greater than 400.
CORRECTED: Orbit readings taken from a Bentley Nevada panel did not display on the Enpac 2500 screen when you set the Auto Advance parameter to ON in
the Instrument Configuration screen.
CORRECTED: The data collector displays two time waveforms instead of an orbit plot when reviewing off route orbit data.
CORRECTED: Improved the data collection performance.
1.03 CORRECTED: The Enpac 2500 may choose an incorrect full-scale range when scaling the data for storage in the database.
CORRECTED: If the battery level was extremely low, the Enpac 2500 would not power off.
CORRECTED: The full scale does not adjust fast enough at the low frequencies range on slow moving machines with low amplitude levels (< .006 ips).
CORRECTED: For AC/DC panel measurements, the Enpac 2500 would apply a load to the panel if the DC bias is < -2 volts.
CORRECTED: The Enpac 2500 takes too long to settle when Trig Level is set to Auto and IEPE power is first applied to the instrument.
CORRECTED: Turning the Enpac 2500 off and on while viewing a route on the PCMCIA card would cause a tuple error.
