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 multimeter.
Reading Memory
The multimeter can store up to 512 readings in internal memory.
Readings are stored in first-in-first-out (
FIFO) order. The first reading
returned is the first reading stored. The reading memory feature is
available only from the front panel.
• 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. Be aware, however, that the function labels
(
VDC, OHM, etc.) are not stored with the reading.
• Readings taken while reading memory is enabled are stored in
volatile memory; the multimeter 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 auto trigger, single trigger,
external trigger, and reading hold. If you configure the multimeter for
multiple readings per trigger, the specified number of readings are
stored in memory each time a trigger is received.
• Front-Panel Operation:
1: RDGS STORE (SYS MENU) store readings in memory
2: SAVED RDGS (SYS MENU) read the stored readings
Reading memory is automatically turned off when you go to the
“parameter” level in the menu to recall the readings. See also “To Use
Reading Memory,” on page 46.
• Remote Interface Operation: The INITiate command uses reading
memory to store readings prior to a FETCh? command. You can query
the number of stored readings in memory by sending the
DATA:POINts? command from the remote interface.
