23 The | (On) key turns the analyzer on, while the Standby key turns most of the
analyzer off. An analyzer alignment is performed (if
Auto Align is on) every time
the analyzer is turned on. After turning on the analyzer, allow 5 minutes of
warm-up time to ensure the analyzer will meet all specifications.
NOTE The analyzer continues to draw power even if the line power switch is in standby.
The detachable power cord is the analyzer disconnecting device.
It disconnects the mains circuits from the mains supply before
other parts of the analyzer. The front-panel switch is only a
standby switch and is not a LINE switch (disconnecting device).
