Route Option Menu
The Route Option menu is accessed by pressing FREQUENCY dial then using the
dial to highlight and click on Test Settings, then using the dial to highlight the text
next to Cal Route: and clicking on it. The menu has the following functionality and
the FREQUENCY dial is used to navigate and select:
• Back – returns to Test Settings menu
• Activate Route – activates the calibration test stored in memory
• Deactivate Route – returns the 699A07 to manual operation, de-activates semi-
automated test
• Load File From USB – shows a list of up to six pre-programmed tests (routes) read
from Calibration_Route folder on USB drive
• Delete Route – returns the 699A07 to manual operation and also deletes the pre-
programmed test from memory
• File Information – displays name of semi-automated test, number of test points
and date it was created. If no test is active pressing file while this option is
highlighted does nothing.
• Eject USB – allows user to safely remove the USB drive from 699A07
Definition of Frequency Units
• Hertz (Hz) is defined as the number of periodic cycles per second and it is a
standard unit for measuring signal frequency.
• CPM stands for Cycles Per Minute. CPM is commonly used for testing industrial
sensors that monitor rotational vibration. 1 Hz=60 CPM
Definition of Amplitude Units
• Root Mean Square (RMS) is a calculation that takes the square root of the average
of the squared amplitudes from a set of data. This type of measurement takes all
amplitudes of a signal into account rather than just one, making it an accurate tool
for an overall calculation.
• Peak (pk) bases calculations on the highest value of the signal generated during
testing. For a sinusoidal wave (as is produced by the 699A07), the peak value is
calculated by RMS*
2. The 699A07 does not measure a true peak value, but
instead estimates the value mathematically based upon the RMS value.
• Peak to Peak (p-p) is a calculation of the difference between the highest positive
peak and the lowest negative peak of a recorded sine wave. The
p-p value is calculated as two times the peak value.
• Gravitational acceleration (g) is the acceleration experienced naturally by objects in
earth’s gravitational field. It is approximately equal to
9.80665 m/s
