• Smart HP - (Smart High Pass) Typically this filter maps to a specific
high pass filter in the data collector and is available for magnitude,
spectrum, and time waveform measurements. In the Enpac Ex, it maps
to the Enpac filters shown in the table below, depending on the results
of comparing the filter choice to the formula below.
Emonitor uses the following formula.
Emonitor chooses an overall filter with one of the low frequency cutoffs
shown in the table below. It uses the filter whose cutoff is less than the
result of the formula.
• Overall - Typically this filter maps to a specific high pass filter in the
data collector and is available for magnitude, spectrum, and time
waveform measurements. In the Enpac Ex, it maps to the Enpac filters
shown in the table below, depending on the results of comparing the
filter choice to the formula below.
Emonitor uses the following formula.
Emonitor uses an overall filter with one of the low frequency cutoffs
shown in the table below. It uses the filter whose cutoff is greater than
or equal to the result of the formula.

EXAMPLE
Emonitor uses the 5.30 Hz (318 CPM) filter for an
integrated measurement. It uses the 2.67 Hz (160.2 CPM)
filter for a non-integrated measurement.
