System-Related Operations
This section gives information on topics such as reading memory, errors,
self-test, and front-panel display control. This information is not directly
related to making measurements but is an important part of operating
the meter.
Reading Memory
The meter can store up to 1024 readings in internal memory. Readings
are stored in first-in-first-out (
FIFO
) order. The first reading returned is
the first reading stored. See also “To Use Reading Memory,” on page 50.
•
You can use reading memory with all functions, math operations, and
also reading hold. After you have enabled reading memory, you can
change the function or input channel.
Be aware, however, that the
function labels and channel labels (
V
,
OHM
, etc.) are not stored with the
reading.
•
Readings taken while reading memory is enabled are stored in volatile
memory; the meter clears the stored readings when reading memory is
turned on again, when power has been off, after a self-test, or after a
remote interface reset.
•
You can use reading memory with autotrigger, single trigger, external
trigger, and reading hold. If you configure the meter for multiple
readings per trigger, the specified number of readings are stored in
memory each time a trigger is received.
