1. SAFETY WARNINGS

This instrument has been designed and tested according to IEC

Publication 61010:Safety Requirements for Electronic Measuring

Apparatus. This instruction manual contains warnings and safety

rules which must be observed by the user to ensure safe

operation of the instrument and to retain it in safe condition.

Therefore, read through these operating instructions before

starting using the instrument.

WARNING

● Read through and understand instructions contained in this

manual before starting to use the instrument.

● Save and keep the manual at hand to enable quick reference

whenever necessary.

● Be sure to use the instrument only in its intended applications

and to follow measurement procedures described in the

manual.

● Be sure to understand and follow all safety instructions

contained in the manual.

Not following 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 related parts of the manual for safe operation of

the instrument. Be sure to carefully read the instructions

following each symbol in this 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 minor injury or Instrument damage.

DANGER

● Never make measurement on a circuit having potential of

300VAC or greater.

● Do not attempt to make measurement in the presence of

flammable gasses. Otherwise, the use of the instrument may

cause sparking, which leads to an explosion.

● The transformer jaws are made of metal and their tips are not

completely insulated. Be especially careful about the possible

shorting where the equipment under test has exposed metal

parts.

● Never attempt to use the instrument if its surface or your hand

is wet.

● Do not exceed the maximum allowable input of any

measurement range.

WARNING

● Never attempt to make any measurement, if any abnormal

conditions are noted, such as broken case, cracked test leads

and exposed metal parts.

● Do not install substitute parts or make any modification to the

instrument. Return the instrument to Kyoritsu or your distributor

for repair or re- calibration.

CAUTION

● Not to step on or pinch the cord, or it may damage the jacket of

cord.

● The output connector shall be removed or connected while the

measured conductor are not being clamped. Otherwise, it may

cause a trouble.

● Do not expose the instrument to the direct sun, extreme

temperatures or dew fall.

● Not to give shocks, such as vibration or drop, which may

damage the instrument.

● Use a damp cloth and detergent for cleaning the instrument. Do

not use abrasives or solvents.

2. FEATURES

● Clamp sensor for AC leakage current measurement.

● Designed to safety standard IEC 61010- 2- 032:

6. OPERATING INSTRUCTIONS

DANGER

● In order to avoid possible shock hazard, never make measurement

on circuits having a potential of 300VAC or greater.

● The transformer jaws are made of metal and their tips are not

completely insulated. Be especially careful about the possible

shorting where the equipment under test has exposed metal parts.

CAUTION

● Take sufficient care to not to apply shock, vibration or

excessive force to the jaw tips. Otherwise, precisely adjusted

the jaw tips will be damaged.

● When a foreign substance is stuck in the jaw tips or they

cannot properly engage, the transformer jaws do not fully

close. In such a case, do not release the trigger abruptly or

attempt to close the transformer jaws by applying external

force. Make sure that the transformer jaws close by

themselves after removing the foreign substance or making

them free to move.

● Max. diameter of measured object: Φ24mm for M8141, Φ

40mm for M8142, Φ68mm for M8143. Accurate measurement

cannot be made on a conductor larger than this, because the

transformer jaws cannot fully close.

●When removing the cable from the instrument, grasp the

output connector, not the cable, to avoid damaging the cable.

● When measuring current which pulse element is superposed,

differences of the indicated value may be caused between

ranges, if the peak value exceeds the measurement range to a

large extent. In this case, the reading at the bigger range

should be taken as a right value. Sensitive transformer jaws

are used for Leakage clamp meter. Because of the

characteristics of transformer jaws, which can be opened and

closed, it is impossible to eliminate the interference of external

magnetic field completely. If there is a presence of strong

magnetic field, use the instrument at a distance as far as

possible from it.

Following are the typical things generating magnetic field.

●

Conductor fed large current

●

Motor

●

Equipment which has magnet

●

Integrating wattmeter

6-1 Measuring method

(1) Connect the output connector to the terminal of the instrument.

(2) Press the trigger to open the transformer jaws and close them over

measured conductor.

(3) Make sure that the jaw tips are fully closed.

6-2 Leakage Current Measurement

(1) Measuring out of balance leakage current (See Fig.1):

Clamp onto all conductors except a grounded wire.

(2) Measuring earth leakage current (See Fig.2):

Clamp onto a grounded wire.
