2.3 Connecting the Power Supply and Turning the Power Switch On and Off
Note
If you turn off the main power switch while the front-panel power switch is turned on (while the power switch
is illuminated in green), you can start the instrument the next time by simply turning on the main power
switch. However, if you turn off the main power switch while the front-panel power switch is turned on, the
setup data immediately before the power switch is turned off will not be stored properly.
Power-on Operation
When the power switch is turned on, calibration start automatically. When the instrument starts
normally, the waveform display screen appears. Check that the instrument has started normally before
you use it.
If the Instrument Does Not Start Normally When the Power Is Turned On
Turn off the power switch, and check the following items.
• Check that the power cord is securely connected.
• Check that the correct voltage is coming to the power outlet. See page 2-7.
If the instrument does not operate properly after checking the above, turn on the power switch while
holding down the RESET key. The settings will be returned to their factory default values.
Note
• After turning the power off, wait at least 10 seconds before you turn it on again.
• It may take a few seconds for the startup screen to appear.
• If the instrument still does not start properly even when you turn on the power switch while holding down
the RESET key, contact your nearest YOKOGAWA dealer for repairs.
Turning Off the Power Switch
CAUTION
Abruptly turning off the main power switch or unplugging the power cord while data is being
saved or the internal printer is printing may corrupt the media on which data is being saved or
damage the built-in printer. Also, the data being saved is not guaranteed. Always turn the main
power switch off after data has been saved.
