This instrument has been designed and tested according to IECPublication 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 retain it in safe condition. Therefore, read throughthese operating instructions before starting using the instrument.
●Read through and understand instructions contained in this manual
before starting using the instrument.
●The instrument is to be used only in its intended applications.
●Understand and follow all the safety instructions contained in themanual.
Failure to follow the instructions may cause injury, instrument
damage and/or damage to equipment under test. Kyoritsu is by nomeans liable for any damage resulting from the instrument incontradiction to this cautionary note.

●Do not attempt to make measurement in the presence of flammablegasses, fumes, vapor or dust. Otherwise, the use of the instrument
may cause sparking, which can lead to an explosion.
●Do not exceed the maximum allowable input of any measurement range.
●Never open the battery compartment cover while making measurement.
●The instrument should be used only in its intended applications or conditions.
Otherwise, safety functions equipped with the instrument do not work,
and instrument damage or serious personal injury may be caused.
●Verify proper operation on a known source before use or take action
as a result of the indication of the instrument.
●Keep your fingers and hands behind the protective fingerguard during
a measurement.

●Stop using the test lead if the outer jacket is damaged and the inner
metal or color jacket is exposed.
