Read the following safety information. [Read the next page.]
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.”

Warnings (cont'd)
When exchanging the input signal or ending the
operation after measurement, turn off the target to
be measured, and be sure to discharge electrical
charge by selecting either Method 1 or Method 2
below, whichever is safer.
Failure to do so may cause an electrical shock or instrument 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. Take the following steps.
(1) Turn off the power to the circuit to be measured.
(2) Turn the POWER switch to standby.
(3) Open the insulation cover.
(4) Discharge through the earth terminal by using a grounding rod, etc.
(5) Disconnect the probe and measuring cable.
If the red LED turns on when setting the battery
pack to the battery charger, stop charging and do
not use the battery pack.
If you continue using the battery pack, it may cause fire or unit malfunction.
Consult Iwatsu office or our sales distributors.
If the red LED blinks when setting the battery pack to the battery charger, calibration of the battery pack
is necessary. Use the charging and calibration mode. (See 2.2.3)
If smoke, abnormal odor, or abnormal sound
emanates from this instrument, immediately take
the following actions and disconnect the power
cord from the receptacle.
Isolation Unit:
(1) Turn off the power to the circuit to be measured.
(2) Turn the POWER switch to standby.
(3) Open the insulation cover.
(4) Discharge through the earth terminal by using a grounding rod, etc.
(5) Disconnect the probe and measuring cable.
(6) Remove the battery pack.
Isolation Amplifier:
(1) Turn off the power switch.
(2) Disconnect the power plug from the receptacle.
Failure to do so may cause an electrical shock or fire. After taking the above actions, contact Iwatsu
office or our sales distributors for repair. Never repair this instrument by yourself, doing so is
dangerous.
