• Check that the power cord is connected properly (see section 3.6, “Connecting the
Power Supply”).
• Check that the circuit under measurement is wired properly (see sections 3.7 “Directly
Wiring the Circuit under Measurement,” 3.8 “Using an External Current Sensor to Wire
the Circuit under Measurement,” 3.9 “Using an External PT or CT to Wire the Circuit
under Measurement,” and 3.10 “Wiring a Circuit with Voltage Input Exceeding 600 V.”

The Order in Turning ON/OFF the Power
When using the model with the SCSI option and you wish to save or load data using an
external SCSI device, turn ON the SCSI device first, then turn ON this instrument. When
turning OFF the instrument and SCSI device, reverse the order.
Power Up 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 is displayed when the
power switch is turned OFF.
Note
If the instrument does not operate as described above when the power switch is turned ON,
turn OFF the power switch and check the following points.
•
Check that the power cord is securely connected to the outlet.
•
Check that the correct voltage is coming to the power outlet (see section 3.6, “Connecting
the Power Supply.”
•
Check that the fuse is not blown (see section 16.5, “Replacing the Power Fuse”).
•
If the power switch is turned ON while pressing the RESET key, the setting parameters
are initialized to their factory default values. For information on initialization, see section
4.2, “Initializing the Settings.”
If the instrument still does not work after checking these points, contact your dealer for
repairs.
