Safety Information
Safety Information
This unit is designed to comply with IEC 61010 Safety Standards, and
has been thoroughly tested for safety prior to shipment. However, mishandling during use could result in injury or death, as well as damage
to the unit. Be certain that you understand the instructions and precautions in the manual before use. We disclaim any responsibility for accidents or injuries not resulting directly from unit defects.
This manual contains information and warnings essential for safe operation of
the unit and for m aintaining it in s afe operating condition. B efore using i t, be
sure to carefully read the following safety precautions.
Safety Symbols
In the manual, the symbol indicates particularly important
information that the user should read before using the unit.
The symbol printed on the unit indicates that the user should
refer to a corresponding topic in the manual (marked with the
symbol) before using the relevant function.
Other Symbols
Indicates AC (Alternating Current).
Indicates a grounding terminal.
Indicates a fuse.
Indicates the ON side of the power switch.
Indicates the OFF side of the power switch.
The following symbol s in this manu al indicat e the rela tive importance of c autions and warnings.
Indicates that incorrect operation presents a significant hazard that could result in serious inju ry or death to the user.
Indicates that inc orrect operation presents a possi bility of
injury to the user or damage to the unit.
Indicates advisory items related to performance or corr ec t
operation of the unit.
Indicates a prohibited action.
Indicates the location of reference information.
Indicates quick references fo r operati on and remed ies for

Measurement Categories (Overvoltage categories)
To ensure safe operation of measurement units, IEC 60664 establishes
safety standards fo r various electrical environ ments, catego rized as CAT I to
CAT IV, and called overvoltage categories. These are defined as follows.
CAT I: Secondary electrical circuits connected to an AC elec-
trical outlet through a transformer or similar device.
CAT II: Primary electrical cir cuits in equipment connected to
an AC electrical outlet by a power cord (portable tools,
household appliances , etc.)
CAT III: Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distributi on panel to outlets.
CAT IV: The circuit from the service drop to the service
entrance, and to t he power meter and primary overcurrent protection device (distribution panel).
3
Safety Information
Accuracy
Higher-numbered categories correspond to electrical environments with
greater momentary ener gy. So a meas urement device designed for CAT III
environments can endur e greater mo mentary en ergy than a de vice design ed
for CAT II.
Using a measurement uni t in an environment desig nated with a high er-numbered category than that for which the unit is rated could result in a severe
accident, and must be carefully avoided.
We define measuremen t t olera nces in ter m s of rdg . (r eadin g) and dgt . ( di git) va lues, with the following meanings:
rdg.
(reading or displayed value)
The value currently bei ng measured and
indicated on the measuring unit.
dgt. (resolution) The smallest dis playable unit o n a digital
measuring unit/ device/ product, i.e., the
input value that cau ses the digi tal display
to show a "1" as the least-significant digit.

2.2 Checking the Power Voltage
2.2 Checking the Power Voltage
• Before turning the unit on, make sure the supply voltage matches
that indicated on the its power connector. Connection to an improper
supply voltage may damage the unit and present an electrical hazard.
• The power of the unit can be changed with the voltage selectors. To
avoid an electric accid ent, use t he unit wit h the voltage sele ctors set
to a voltage value that matches the voltage to be used.
• Make sure the power is off when you change the voltage with the voltage selectors. Changing the power voltage when the power is on may
result in damage to the unit or an electric accident.
• The maximum rated power is 110 VA.
The power voltage spec ification of the un it is set as spec ified when the uni t
was ordered.
You can select from 100 V, 120 V, 220 V, and 240 V.
You can determine which voltage is set by checki ng the positi ons of the vo ltage selectors.
Refer to the diagram between the voltage select or s.

2.3 Connecting the Power Cord
2.3 Connecting the Power Cord
To avoid electrical acc idents and to maintain the safety specifications
of this unit, connect the power cord only to a 3-contact (two-conductor
+ ground) outlet.
• To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging it from the power outlet.
• Turn off the power before disconnecting the power cord.

Connection
Procedure
1. Make sure the power switch of the unit is off.
2. Make sure the power voltage matches and connect the power
cord to the power inlet with voltage selectors on the rear of the
unit.
3. Insert the plug into the power outlet.

• Do not apply a voltage to the measur ement ter minals. Doing so may damage the unit.
• When disconnectin g the
pulling off the connector. Forcibly pulling the connector without releasing
the lock, or pulling on the cable, can damage the connector.
• To avoid breaking the probes, do not bend or pull them.
• The ends of the probes are sharp. Be careful to avoid injury.

Measurement Chapter 3
3.1 Pre-Operation Inspection
To ensure safe use of the unit, be sure to check the following inspection
items prior to performing measurements.
Items Countermeasure See:

Inspect the unit, probe, and
fixture
(Are there any damaged
parts?)
Inspect the connection cord
(Is the covering c racked or is
any metal exposed?)
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?)
When the power is turned
on, does the fan spin and do
the “3504 (3504-10)” and
version number indications
appear on the MAIN display
area?
Does the CV LED light up
when measurement is performed with the measurement terminals open while
the probe and fixture are
connected to th e un it ?

If there is damage:
Unit and fixture: Submit them for repairs.
Probe: Replace it with a new one.
Do not use a damaged cord because doing so
may result in electric shock. (Replace the cord
with a new one.)
Use of the unit outside the specified power supply 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.
If the fan does not spin or the “3504 (3504-10)”
and version number indications are not displayed, the unit may be malfunctioning. Submit
it for repairs.
If the CV LED does not light up, the unit, probe,
or fixture may be malfunctioning.
Unit and fixture: Submit them for repairs.
Probe: Replace it with a new one.

3.1 Pre-Operation Inspection
Items Countermeasure See:
Are the measur ement values
indicated on the unit normal
when measuring known
samples such as standard
capacitors?
If the measurement values are abnormal, check/
perform the following.
• Are the me asurement conditions set appropriately?
• Perform open circuit and short circuit compensation again.
• Turn load compensation off.
If the measurement values are still abnormal after 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.
