DANGER
●
The instrument is to be used only in its intended applications or conditions. Otherwise,
safety functions equipped with the instrument will not work, and instrument damage or
serious personal injury may occur. Verify proper operation on a known source before taking
action as a result of the indication of the instrument.
●
Wear protective insulated gears if electrical shock or other danger is possible.
●
This instrument is rated to 300 V AC for CAT IV, 600 V AC for CAT III, and 1000 V AC for CAT
II. With attention to the measurement category to which the object under test belongs, do not
make measurements if voltage against earth in the circuit under test exceeds these values.
●
Do not attempt to make measurement in the presence of flammable gasses. Otherwise,
the use of the instrument may cause sparking, which can lead to an explosion.
● N
ever attempt to use the instrument if its surface or your hand is wet.
- Measurement -
● Do not exceed the maximum allowable input of any measuring range.
● Never open the
battery compartment cover during a measurement.
- Clamp sensor -
● Confirm that the measured current rating of the
circuit under test and the instrument;
in addition, don’t exceed the rated voltage against earth.
● Keep your fingers behind the barrier during a measurement.
Barrier: provides protection against electrical shock and ensuring the minimum required
clearance and creepage distances.
● Connect to the
secondary side of a circuit breaker since a current capacity at the
primary side is large and dangerous.
● Do not touch two lines under test
when opening the jaws.
- Test leads -
● Use only the ones supplied with th
e instrument.
● When the instrument and the test lead are combined and used together, whichever lower
category either of them belongs to will be applied. Confirm that the measured voltage rating
of the test lead is not exceeded.
●
Connect the cables that are required for the desired measurement only.
● Connect
the test leads to the instrument first, and only then connect them to the circuit
under test.
● Keep your fingers behind the barrier duri
ng a measurement.
Barrier: provides protection against electrical shock and ensuring the minimum required
clearance and creepage distances.
● Never disconnect the test leads from the
voltage input terminals of the instrument during
a measurement (while the instrument is energized).
● Do not touch two lines under test with the metal tips of the test leads.
● Never touch the metal tips of the test leads.
- Battery -
● Do not try to replace the batteries during a measurement.

WARNING
● Never attempt to make any measurement if any abnormal conditions, such as a broken
cover or exposed metal parts are present on the Instrument, or test leads.
●
Verify proper operation on a known source before use or taking action as a result of
indication of the instrument
● Do not install substitute parts or make any modification to the instrument. Return the
instrument to your local KYORITSU distributor for repair or re-calibration in case of
suspected faulty operation.
CAUTION
●
Use of this instrument is limited to domestic, commercial and light industry applications.
Strong magnetic interference or strong magnetic fields, generated by large currents, may
cause malfunction of the instrument.
●
Caution should be taken since conductors under test may be hot.
●
Never apply currents or voltages exceeding the maximum allowable input to each range.
● Do not apply currents or voltages for the test leads or
current sensors while the instrument
is off.
● Don’t use the instrument at dusty places or to be spattered.
● Don’t use the instrument under a strong electric storm or in t
he vicinity of energized object.
● Never give strong vibrations or drop shocks.
- Test leads -
●
Connect the plug firmly to the corresponding terminal.
●
Do not pull or twist the test leads with excessive force to prevent damage.
- Battery -
●
Brand and type of the batteries should be harmonized.
- Treatment after use -
●
Set the function switch to “OFF” position and remove all the cables from the instrument.
●
Take out batteries if the instrument is to be stored and will not be in use for a long period.
● Never give strong vibrations or drop shocks when carrying the instrument.
● Do not expose the instrument to direct sunlight, high temperature, humidity or dew.
● Use a damp cloth with neutral detergent or water for cleaning the instrument. Do not use
abrasives or solvents.
●
If the instrument is wet, dry and store it.
Carefully read and follow the instructions with
