Turning On and Off the Power Switch
Before Turning On the Power, Check That:
• The instrument is installed properly. → section 3.2, "Installing the 2560A"

Turning On and Off the Power Switch
The power switch is a push button. Press the button once to turn the instrument on and press it again
to turn the instrument off.
Operations Performed When the Power Is Turned On
When the power switch is turned on, a self-test starts automatically. When the self-test completes
successfully, the instrument will be configured with the settings that were in use immediately before
the power was turned off. For the settings that are retained even when the power is turned off, see
appendix 7.
Check that the instrument has started normally before you use it.
If the 2560A Does Not Start Normally When the Power Is Turned On
Turn off the power switch, and check the following items.
• The power cord is securely connected.
• The correct voltage is coming to the power outlet. → section 3.3, "Connecting to the Power
Supply"
• Initialize the 2560A settings → section 15.8, "Initializing the Settings."
If the 2560A still does not work properly after checking these items, contact your nearest
YOKOGAWA dealer for repairs. If an error code is displayed, check the information in section 15.3,
and take the appropriate actions.
Note
After turning the power switch off, wait at least 10 seconds before you turn it on again.
To Generate Accurate Output
• Allow the instrument to warm up for at least 30 minutes after turning on the power switch. If
the instrument has been stored in a hot-temperature, high-humidity environment, warm up the
instrument for at least a day before starting use.
Keep the OUTPUT switch turned off during warm up.
• We recommend that the power be left on at all times.
