Turning the Power On
Hold down the power switch on the instrument’s front panel for at least 2 seconds. When the instrument starts normally, the power
switch (POWER LED) lights, and the start screen appears.
When the Power-on Operation Does Not Finish Normally
Turn off the power switch, and check the following items.
• Is the USB-AC adapter connected correctly? See page 27.
• Are you holding down the power switch for at least 2 seconds?
If the instrument still does not work properly after checking these items, contact your nearest YOKOGAWA dealer for repairs.
Warm Up
To enable more accurate measurements, allow the instrument to warm up for at least 5 minutes after it is turned on.
Power-off and Sleep State
When the instrument is running normally with the power switch turned on, you can temporarily turn the power off to a sleep state.
The operation varies depending on how long you hold down the power switch.
• Turning the Power Off
If you hold down the power switch for 3 seconds or longer, a shutdown message appears on the screen, the power is turned off
completely, and the power switch (POWER LED) turns off.
• Sleep State
If you hold down the power switch for less than 3 seconds and release it, the screen turns off, and the instrument enters the sleep
state. In this case, the power switch (POWER LED) remains on. To release the sleep state, hold down the power switch. In the sleep
state, the instrument consumes the minimum amount of power. In the sleep state, the setup screen that you were using, the character
input screen, or the like is retained. When you turn on the power switch again, the original screen is restored. If the sleep state
continues for 2 hours, the power is turned off automatically.
