2.5 Turning the Power On and Off
Before turning the instrument on, make sure the supply voltage matches
that indicated on the its power connector. Connection to an improper sup-
ply voltage may damage the instrument and present an electrical hazard.
To avoid damaging the power cord, grasp the plug, not the cord, when unplug-
ging it from the power outlet.
• Allow 10 minutes warming up after powering on.
The Remote Control Box, external I/O device, RS-232C interface, and GP-IB
interface are active only when they are connected prior to startup. If these
devices are connected after the power is turned on, thus causing a malfunc-
tion.
• After the power has been switched off, wait for about 5 minutes before turning
on the power again.
