Recalling readings
To recall the data stored in a reading buffer, press the
RECALL
key.
NOTE (Models 2601A/2611A/2635A) Pressing the
RECALL
key toggles
between the two dedicated reading buffers for Channel A. (Models
2602A/2612A/2636A) Pressing the
RECALL
key cycles through the
reading buffers for each channel. Channel A, Buffer 1 is always the
first buffer displayed.
The reading display is on the top left, while the buffer location number is on the right. The source
values are positioned at the lower left side of the display (if enabled), while the time stamp (if used)
is positioned at the lower right side. When toggling between buffers with
RECALL
, the source
display field will identify the buffer: SrcA1 (Buffer 1, Channel A), then SrcA2 (Buffer 2, Channel A);
followed by (Model 2602A/2612A/2636A only) SrcB1 (Buffer 1, Channel B) then SrcB2 (Buffer 2,
Channel B).
Buffer location number
The buffer location number indicates the memory location of the source-measure reading. For
example, location #000001 indicates that the displayed source-measure reading is stored at the first
memory location.
Time stamp
If the time stamp is enabled, the first source-measure reading stored in the buffer (#0000001) is
time stamped at .000 seconds. Subsequent readings are time stamped relative to when the first
measurement was made. The interval between readings will depend on the reading rate.
Displaying other buffer readings
Turn the
navigation wheel
to increment and decrement the selected digit of the location number
by one. Press the
navigation wheel
or
CURSOR
keys to move to the next digit that the
navigation wheel
will change.
To exit from the reading buffer recall mode, press
EXIT
.
Working with reading buffers in the remote state
Readings can be obtained in multiple ways including synchronous or overlapped measurements.
Routines that make single point measurements can be configured to make multiple measurements
where one would ordinarily be made. The measured value is not the only component of a reading.
The measurement status (for example, “In Compliance” or “Overranged”) is also an element of
data associated with a particular reading.
All routines that return measurements can return the measurements in the reading buffers.
Overlapped measurements always return readings in a reading buffer. Synchronous measurement
functions can return single-point measurement values or store multiple values in a reading buffer.
