EU Label
Choose the Engineering Units Label for the selected input. The displayed units change
from Volts to the EU Label when Engineering Units are On. Choose USER for the user
defined User Label.
Input units of acceleration (m/s
2
, in/s
2
, or g), velocity (m/s or in/s), and displacement (m
or in) may be converted in the frequency domain using Transducer Convert. For
example, the FFT of an input configured for an accelerometer with Engineering Units of
m/s
2
may be displayed in displacement (meters) using Transducer Convert.
The two inputs may have different EU Labels. For instance, if Ch2 has EU Label set to
m/s
2
, and Ch1 has EU Label set to dyne, then the units of the frequency response
measurement will be m/s
2
/dyne.
Note that this softkey applies to an input channel, unlike most softkeys which apply to a
specific display.
Command: EU1L (?) {i}
Command: EU2L (?) {i}
EU / Volt
Set the Engineering Units per Volt scale factor for the selected input. This factor is used
to scale the display units from Volts to Engineering Units when Engineering Units are
On. The displayed units change from Volts to the EU Label.
The EU scale factor may be entered in EU/V, V/EU, or dB(EU/V).
Note that this softkey applies to an input channel, unlike most softkeys which apply to a
specific display.
Command: EU1V (?) {x}
EU2V (?) {x}
EUs at Marker
Calculate the EU/Volt scale factor for either the selected input based upon the marker
reading in the active display. Enter the desired calibrated value for the marker reading (in
the display units).
The active display measurement must be a single channel measurement and Engineering
Units must be On.
This feature is normally used for the input channel which is being measured in the active
display. In this case, the active display marker reading changes to the calibrated value.
