Inspect the connection cord
(Is the covering cracked or is any
metal exposed?) Do not use a damaged cord because doing so
may result in electric shock. (Replace the cord
with a new one.)

Check the power supply voltage
setting
(Does the setting of the voltage
selector on the rear of the unit
match the power supply voltage to
be used?) Use of the unit outside the specified power sup-
ply voltage range may result in the unit being
damaged or an electrical fault. Set the voltage
selector in accordance with the power supply
voltage to be used. Setting the Voltage
Selector:

Power Voltage" (p. 18)
When the power is turned on,
does the fan spin and do the
“3504-40, 3504-50, 3504-60” and
version number indications ap-

Are the measurement values indi-
cated on the unit normal when
measuring known samples such
as standard capacitors? If the measurement values are abnormal,
check/perform the following.
• Are the measurement conditions set appro-
priately?
• Perform open circuit and short circuit com-
pensation again.
• Turn load compensation off.
• Set an appropriate trigger delay time or wait
time for trigger synchronous output function.
If the measurement values are still abnormal af-
ter you have checked/performed the above, the
unit, probe, or fixture may be malfunctioning.
Unit and fixture: Submit them for repairs.
Probe: Replace it with a new one.
