Warnings
To prevent electrical shock, never touch the probe
cable if a circuit to be measured is connected to the
Isolation Unit during measurement.
For explanations of floating measurement, refer to “7.1 Precautions when using probes during floating
measurement.”
Never touch the probe cable or BNC cable during
measurement or voltage application. Even after
measurement, turn off the power to the target to be
measured, and be sure to discharge electrical
charge by selecting either Method 1 or Method 2
below, whichever is safer. Never touch these parts
until safety is confirmed (Isolation Unit).
Touching the probe cable or BNC cable during measurement or voltage application may cause electrical
shock, fire, or unit malfunction.
• Method 1: Discharge the electrical charge through the target to be measured by using a grounding rod,
etc.
• Method 2: Discharge the electrical charge through the earth terminal inside the front insulation cover of
the Isolation Unit by using a grounding rod, etc. Never touch any parts inside the Isolation
Unit except the earth terminal.
This instrument is capable of floating measurement.
Nevertheless, be aware of the relations among the
input withstand voltage, measurement potential,
and reference potential, and take into consideration
the operating ratings of the outer sheath of the
coaxial cable and ground leads (Isolation Unit).
When performing floating measurement by using the voltage probe, the reference potential must not be
raised to the input withstand voltage. The reference potential that can be used for floating is determined by
the rated voltage of the outer sheath of the coaxial cable of the probe and GND leads.
Measurement without taking into consideration the relation among the input withstand voltage,
measurement potential, and reference potential, and the operating ratings of the outer sheath of the coaxial
cable and GND cable may cause an electrical shock, fire, or failure.
For details about the recommended probe and rated operating voltage of this instrument, and for examples
of connection for floating measurement, refer to “7.1 Precautions when using probes during floating
measurement.”

1.1 Applications
This Isolation Probe (referred to as “this instrument” hereinafter) has been developed for the applications
exemplified as follows.
 For the analysis of generating mechanism for the failure parts of power plants, large industrial
machineries, etc.
 For developing new technologies of power electronics instruments, measurement of high voltage such
as railroad applications, remote control and measurement, etc.
1.2 Characteristics
This instrument is a system consisting of an Isolation Amplifier (SE-6000), Isolation Unit (SE-6011), battery
pack, and optical fiber cable (see 1.3). Characteristics of this system will be explained below.
(1) Wide bandwidth
It has a bandwidth of 30MHz, and can be used with such digital oscilloscopes as our ViewGo II series.
(2) High voltage measurements
High voltage measurement can be carried out safely, because the Isolation Unit (measurement unit)
and Isolation Amplifier (operation unit) are electrically isolated by optical fiber cable.
Additionally, measurements with low common mode noise, thereby obtaining data with small distortion,
can be performed because the Isolation Unit is driven by the battery pack.
(3) Measurements from a distance
Measurements from a distant place (50m with optical fiber SE-607) are possible, because the Isolation
Amplifier and Isolation Unit are connected by optical fiber cable.
