Items to Be Checked before Turning ON the Power
• Check that the instrument is installed properly (see section 3.2, “Installing the

• Check that the power cord is connected properly (see section 3.3, “Connecting the
Power Supply”).

Power ON Operation
When the power switch is turned ON, the self-test starts automatically. When the self-
test completes successfully, the display shows the screen that was displayed
immediately before the power switch was turned OFF. Before using the instrument,
check that the self-test completes successfully.
When the Power-on Operation Does Not Finish Normally
Turn OFF the power switch and check the following points.
• That the power cord is securely connected.
• That the correct voltage is coming to the power outlet (see section 3.3, “Connecting
the Power Supply”).
• That the fuse is not blown (see section 11.5, “Replacing the Power Fuse”).
• If the power switch is turned ON while holding down RESET, the setup parameters
are initialized to their factory default values. For the initial settings, see appendix 3.13.
If the instrument still does not work properly when the power switch is turned ON after
checking these items, contact your nearest YOKOGAWA dealer for repairs.
