●Safety warnings

This instrument has been designed, manufactured and tested according to IEC 61010-1: Safety

requirements for Electronic Measuring apparatus, and delivered in the best condition after passing

quality control tests.

This instruction manual contains warnings and safety procedures which have to be

observed by the user to ensure safe operation of the instrument and to maintain it in safe

condition. Therefore, read through these operating instructions before using the

instrument.

WARNING

- For about Instruction manual -

●Read through and understand the instructions contained in this manual before using the

instrument.

●Keep the manual at hand to enable quick reference whenever necessary.

●The instrument is to be used only in its intended applications.

●Understand and follow all the safety instructions contained in the manual.

●Read the enclosed Quick manual after reading this instruction manual.

●As to the Clamp sensor use, refer to the instruction manual supplied with the sensor.

It is essential that the above instructions are adhered to. Failure to follow the above instructions

may cause injury, instrument damage and/or damage to equipment under test.

The symbol indicated on the instrument, means that the user must refer to the related parts in

the manual for safe operation of the instrument. It is essential to read the instructions wherever the

symbol appears in the manual.

DANGER : is reserved for conditions and actions that are likely to cause serious or fatal injury.

WARNING : is reserved for conditions and actions that can cause serious or fatal injury.

CAUTION : is reserved for conditions and actions that can cause injury or instrument damage.

O Measurement Category

To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for

various electrical environments, categorized as O to CAT.IV, and called measurement categories.

Higher-numbered categories correspond to electrical environments with greater momentary

energy,

so a measuring instrument designed for CAT.III environments can endure greater momentary

energy

than one designed for CAT.II.

O : Circuits which are not directly connected to the mains power supply.

CAT.II : Electrical circuits of equipment connected to an AC electrical outlet by a power cord.

CAT.III : Primary electrical circuits of the equipment connected directly to the distribution panel,

and feeders from the distribution panel to outlets.

CAT.IV : The circuit from the service drop to the service entrance, and to the power meter and

primary overcurrent protection device (distribution panel).

DANGER

●Verify proper operation on a known source before use.

●Verify proper operation on a known source before taking action as a result of the indication of

the instrument.

●Never make measurement on a circuit in which the electrical potential exceeds 600VAC.

●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.

●Never 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 cover during a measurement.

- Battery -

●Do not try to replace batteries during a measurement.

●Brand and type of the batteries to be used should be harmonized.

- Power cord -

●Connect the Power cord mains plug to a mains socket outlet.

●Use only the Power cord supplied with this instrument.

- Power supply connector -

●Never touch the Power supply connector although it is insulated while the instrument is

operating

with batteries.

- Voltage test leads -

●Use only the ones supplied with this instrument.

●Confirm that the measured voltage rating of the test lead is not exceeded.

●Do not connect a Voltage test lead unless required for measuring the parameters desired.

●Connect Voltage test leads to the instrument first, and only then connect them to the circuit

under

test.

●Never disconnect Voltage test leads while the instrument is in use.

●Connect to the downstream side of a circuit breaker since a current capacity at the upstream

side

is large.

●Do not touch two lines under test with the metal tips of the test leads.

●Never touch the metal tips of the test leads.

- Clamp sensor -

●Use only the ones dedicated for this instrument.

●Confirm that the measured current rating of the test lead is not exceeded.

●Do not connect a Camp sensor unless required for measuring the parameters desired.

●Connect sensors to the instrument first, and only then connect them to the circuit under test.

●Never disconnect sensors while the instrument is in use.

●Connect to the downstream side of a circuit breaker since a current capacity at the upstream

side

is large.

●Do not touch two lines under test with the metal tips of the test leads.

WARNING

- Connection -

●Confirm that the instrument is off, and then connect the Power cord.

●Connect the Power cord, Voltage test leads and Clamp sensors to the instrument first. Cord to

be firmly inserted.

●Never attempt to make any measurement if any abnormal conditions, such as a broken cover

or exposed metal parts are present on the Instrument, Voltage test leads, Power cord and

Clamp

sensor.

- Measurement –

●Ensure that the Current input terminal cover, USB connector cover and SD card connector cover

are closed when not in use during a measurement.

- Not in use for a long period -

●Remove the Power cord from the outlet if the instrument will not be in use for a long period.

- Repair/ Calibration -

●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.

- Battery -

●Do not try to replace the batteries if the surface of the instrument is wet.

●Ensure that the Power cord, Voltage test leads and Clamp sensor are removed from the

instrument, and that the instrument is switched off when opening the Battery cover for battery

replacement.

●Never mix new and old batteries.

●Install batteries in correct polarity as marked inside the Battery compartment area.

- Power cord -

●Do not use the damaged cord.

●Don’t put heavy things on, step on or pinch the cord, moreover, not to touch any heating

material.

●When unplugging the cord from the mains socket outlet, do so by removing the plug first and not

by pulling the Power cord.

- Measures against abnormal symptoms -

●If the instrument begins to emit smoke, becomes too hot, or gives off an unusual smell,

immediately power it off and disconnect the power cord from the outlet. Also power off the power

to the object under test. If any anomalies as noted, contact your local KYORITSU distributor.

- Use of protective gears -

●Use insulated gloves, boots or head gears at measurements to ensure user’s safety.

CAUTION

●Caution should be taken since conductors under test may be hot.

●Never apply currents or voltages exceeding the maximum allowable input for the instrument for a

long time.

●Do not apply currents or voltages for the Voltage test leads or Clamp 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 the vicinity of energized object.

●Never give strong vibrations or drop shocks.

●While using a SD card, do not replace or remove the card. ( symbol blinks while accessing

SD card.)

Otherwise, the saved data in the card may be lost or the instrument may be damaged.

- Clamp sensor -

●Do not bend or pull the cable of the Clamp sensor.

- Treatment after use -

●Power off the instrument and disconnect the Power cord, Voltage test leads and Clamp sensors

from the

instrument.

●Remove the batteries if the instrument is to be stored and will not be in use for a long period.

●Remove the SD card when carrying the instrument.

●Never give strong vibrations or drop shocks when carrying the instrument.

●Do not expose the instrument to direct sunlight, high temperatures, humidity or dew.

●Use a damp cloth with neutral detergent or water for cleaning the instrument. Do not use

abrasives or solvents.

●Do not store the instrument if it is wet.
