Front Panel Operation
3-84
CLEAR-ALL
This action can be used at any time to clear the data buffer of
all stored readings and buffer statistics. Since the MEM1 and
MEM2 memory options are non-volatile, clear-all is the only
way for the operator to clear the reading buffer.
COUNT
With this menu selection, you specify the number of read-
ings to store. Highlighting it and pressing ENTER yields the
following display:
SET BUFFER SIZE
ENTER-COUNT USE-TRIGGER-MODEL
ENTER-COUNT: This item allows you to specify the buff-
er size in number of readings.
USE-TRIGGER-MODEL: This selection lets you default
to the measure count in the present trigger configuration, as
long as the measure count is a finite value.
FEED
This selection allows you to select the source of readings to
be placed in the buffer. It has the following submenu:
CHOOSE BUFFER FEED
AFTER-CALC BEFORE-CALC NONE
AFTER-CALC: With this item, readings are stored in the
buffer after any enabled math operations are performed
(mX+b or percent).
BEFORE-CALC: With this item selected, readings are
placed in the buffer before any math is performed (mX+b or
percent).
NONE: With NONE selected, no readings are placed in the
buffer when storage is performed. Pressing the STORE key
changes NONE to the AFTER-CALC selection.
3.8.3 Storing and recalling readings
Tables 3-33 through 3-35 detail the sequence of steps for the
various modes of buffer control. The tables assume the buffer
is configured as explained in paragraph 3.8.2.
Note that during data storage, the reading number on the bot-
tom line of the display is one ahead of the reading on the top
line.
There are “multiple displays” available when recalling buff-
ered readings. These are explained in paragraph 3.8.4.
