Set the value (data) using the data entry keys [0]-[9]. Use [-] to indicate a negative
value. Use [.] to enter a decimal point for fractional values. Edit the field value by

.

If you attempt to enter a new value outside the value’s defined limits the interface
defaults the value to the nearest limit. For example: if you enter 900 when the
minimum value is 1000, the new value will be 1000.

Defining Sample Rate and Positioning

Press [F4]to configure sample rates, from 0 msec (maximum collection speed) to
20.000 seconds.

When the drive collects samples, it uses part of the buffer to store values prior to
the trigger point, and the remainder of the buffer for values after the trigger. Press
[F5] to define the percentage of the trend buffer to allocate to values collected
after the trigger occurrence. Edit this data field in the same manner as the trigger
data.
