The value (data) is set through the use of the numerical keypad. Use
the data entry keys [0]-[9] to enter the new value. The [-] key can be
typed at any time to enter a negative value. The [.] key is used to
enter a decimal point for fractional values. The entered new value
can be edited by pressing the [backspace] key. This key will delete
the right most character (i.e. number, decimal point or negative sign)
shown on the screen. Press the [enter] key to accept the new value as
shown in Figure 3.82. If the new value that you entered is outside
the limits defined, the new value will be pegged at the closest limit.
For example: If you entered 900 when the minimum value was 1000,
the new value will show 1000.
Some data must be entered in HEX. To accomplish this, use the
cursor up/down keys to scroll through the values 0-F for the right
most digit. To accept the digit and enter to the right of the current
digit, press the right cursor key. Press the [Enter] key to accept the
value.
The value may be edited the same as a value entered from the
numeric keypad.
Figure 3.82 – Trigger Condition
Defining Sample Rate and Positioning
Pressing the [F4] key sets the rates at which the samples are taken.
This data field is then modified in the same manner as the trigger
data is entered. Rates can be set from 0 msec (collect as fast as
possible) to 20.000 seconds.
When samples are collected, part of the buffer will store values prior
to the trigger point and the remainder of the buffer will store values
after the trigger. Pressing the [F5] key will allow you to set the
percentage of the trend buffer, allocated to values collected, after the
trigger has occurred. This data field is modified in the same manner
as the trigger data is entered.
