Warning
iii
Installation
• Do not use in an environment with explosive gases. It may cause an explosion.
• If you notice smoke, foul odor or abnormal noise, immediately stop measuring
to avoid electric shock or fire. Turn off the instrument to be measured and
disconnect the power cable from the power outlet. Please contact our Homepage
listed at the end of this manual or our sales distributor. Do not attempt to repair
the unit yourself.
Power Supply
• Always use this instrument only within the rated operating voltage. If used over
the rated range, electric shock, fire or failure may occur. The range of operating
voltage is stated on the rear panel.
This instrument runs on single-phase, 115 V (90 to 132 V) or 220 V (180 to 250
V), AC power source at 45 to 66 Hz. No voltage selection is required, as the
instrument automatically adapts to the line voltage.
• Use a 3-prong grounded power cord. By connecting the attached 3-prong power
cord to a 3-wire receptacle, the grounding wire of the power cord is connected
to ground. If this is not done, an electric shock or instrument damage could
result. When supplying power from a 2-wire receptacle using a 3-prong/2-prong
conversion adapter, connect the grounding terminal of the 3-prong/2-prong
conversion adapter to ground.
• Use of a 2-prong power cord may result in electric shock.
If the supply voltage is of a 200 V system (200 V to 240 V), use a 200 V system
(rated 250 V) 3-prong power cord.
Read the following safety information.
Warnings

Probe
Grounding lead
The chassis is grounded.

Grounding side
+100 V and the chassis are shorted.
This is dangerous because 100 V is
applied to the chassis.
When measuring
• Connect the probe ground and input connectors to the ground of the device
under test. Refer to “improper ground connections” shown below. Improper
ground connections may cause electric shock or failure of the instrument, the
device under test or other devices connected to the instrument.
[Improper ground connections]
When measuring a floating potential, measurement by the differential method (CH1,
CH2 input) is recommended as shown in the example below.
[Example of recommended measurement]
Read the following safety information.
Warnings
• Power cord
Do not use a damaged power cord or adapter, otherwise fire or electric shock
could result. If the power cord is damaged, please contact our Homepage listed
at the end of this manual or our sales distributor for repair.
• Do not modify the power cord. • Do not pull the power cord.
• Do not forcibly bend the power cord. • Do not heat the power cord.
• Do not twist the power cord. • Do not let the power cord get wet.
• Do not bundle the power cord.
• Do not put heavy objects on the power cord.
v
Operation
• Make sure no water gets on or inside the product
• Do not use the product if wet, otherwise electric shock or fire could result. If
water gets on or inside the unit, turn the power switch to STBY and remove the
power cord. Immediately contact our Homepage listed at the end of this manual
or our sales distributor.
• Do not touch the plug of the power cord with wet hands, otherwise electric
shock could result.
• Operate the instrument on a stable platform. Do not place the instrument on an
unstable support. Dropping the instrument during operation could result in electric
shock, injury, or fire. If the instrument is dropped, turn the power switch to
STBY and remove the power cord. Immediately contact our Homepage listed at
the end of the manual or our sales distributor.
• Do not remove the chassis covers or rear panel. Removing covers exposes lethal
high-voltage circuits within and could result in electric shock.
Please contact our Homepage listed at the end of the manual or our sales
distributor for inspection, calibration, or repair.
• Do not modify this instrument. Modification of this instrument could result in
electric shock, fire, or power failure, and repair of a modified instrument may be
refused.
• Do not operate the instrument in conditions where foreign particles such as metals
or inflammables could pass through the ventilation holes. Operation under these
conditions could result in fire, electric shock, or instrument damage. If any foreign
matter has contaminated the unit, turn the power switch to STBY and remove
the power cord. Immediately contact our Homepage listed at the end of the
manual or our sales distributor.
Warnings
Read the following safety information.
vi
Read the following safety information.
Installation
• Always use this instrument only within the rated operating range. If used over
the rated range, failure may occur.
Use this instrument only indoors.
Operating conditions
Temperature: 0 to +40°C
Humidity: 80% RH or less (non-condensing)
Height: 2,000 meters or less
• Do not block the air ventilation holes or exhaust fan of this instrument. Blocking
the airflow could result in excessive internal heating and fire or electric shock.
• Leave a space behind and to the sides of the instrument.
Be careful to avoid overheating of the instrument when installing the instrument
in a rack mount or on another measurement machine. Failing to observe this
precaution may result in faulty operation or performance.
• Do not place this instrument in a location with excessive moisture or dust,
otherwise fire or electric shock could result.
Power Supply
• Use only the specified fuse (φ5 × 20 mm, 250 V, T3.15 A) when replacing the
fuse. Failure to replace the fuse with the correct rating could result in fire, electric
shock or damage to the unit.
To replace the fuse:
a) Turn the power switch to STBY before disconnecting the power cord.
b) Disconnect the power cord before replacing the fuse.
When measuring
• Do not apply a voltage exceeding the specified value to the input terminals (CH1,
CH2, CH3, CH4). This may cause malfunction. The following is a maximum
voltage that can be input.
Direct
1 MΩ: ±400 V (DC+ACpeak≤5 k Hz)
When SS-0130R (10:1) equivalent probe is used: ±600 V (DC+ACpeak)
[Note]: Maximum voltage that can be input may decrease depending on the
frequency or high voltage pulse of the input signal.
• When a probe or measurement cable is connected, be careful so that you do not
pull the probe or measurement cable causing the instrument to overturn.
Letting the instrument overturn may cause electric shock, injury, fire or
malfunction.
Cautions
vii
Read the following safety information.
Handling
• Set the power switch to STAND BY before connecting or disconnecting the
power cord.
Connecting or disconnecting the power cord while the power is supplied to the
instrument may cause electric shock or malfunction.
• When disconnecting the power cord from the receptacle, remove it by grasping
the plug. Do not pull on the cord itself, as doing so may damage the cord and
could result in fire or electric shock.
• Inspect all cables prior to use. Do not use any damaged cable, otherwise fire or
electric shock could result.
• Do not place any objects on this instrument.
If any objects are placed on this instrument, the cover may be deformed and the
internal circuits shorted, which could result in electrical shock, fire, or damage
to the instrument.
• Be careful not to let the container fall over during set-up and use, otherwise
electric shock, injury, or fire could result.
• Do not use the instrument if broken, otherwise electric shock or fire could result.
Contact our Homepage listed at the end of the manual or our sales distributor for
repair.
• To avoid electric shock or fire, pull out the power supply plug from the outlet for
safety if the instrument will not be used for a long time.
Carrying the instrument
• Dropping the instrument could result in human injury or instrument failure. Be
careful not to drop the instrument and always firmly grasp the middle of the
handle.
(1) Disconnect the cables.
1. Disconnect the power cord and bundle it.
2. Turn counterclockwise and disconnect the connector
of the probe.
(2) Grasp the handle.
1. Raise the handle.
2. Grasp the middle of the handle when carrying
the instrument.
