Real-Time System Clock
During a scan, the instrument stores all readings and alarms with the
current time and date (based on a 24- hour clock).
• When shipped from the factory, the instrument is set to the current
time and date for Greenwich Mean Time (GMT).
• The clock setting is stored in non- volatile memory, and does not change
when power has been off, after a Factory Reset (
*RST
command),
or after an Instrument Preset (
SYSTem:PRESet
command).
Front Panel Operation:

Remote Interface Operation:
The following commands show how to set the
time and date.
Internal DMM Disable
You can scan through the configured channels using either the internal
DMM (an optional accessory with the 34980A) or an external instrument.
For externally- controlled scans, you must either disable the internal DMM
or remove it from the instrument.
• For information on controlling a scan with an external instrument,
refer to
“Scanning With External Instruments” on page 65.
• With the internal DMM disabled, any command received that is directed
to the DMM or requires its use (e.g., configuring a multiplexer channel
for a DMM measurement), will generate an error.
• When you change the state of the internal DMM, the instrument issues
a Factory Reset (
*RST
command).
• If you ordered the internal DMM, it is enabled when shipped from
the factory.
• The internal DMM setting is stored in volatile memory and will
be enabled (ON) when power is turned off or after a Factory Reset
(
*RST
command).
