permitted.
Crossed-out wheel bin symbol (according to WEEE
Directive:
2002/96
/EC) indicating that this electrical
product may not be treated as household waste, but that it
must be collected and treated separately.
#DANGER
●
Never make measurements on a circuit in which earth potentials of
45
Vpk or higher exist.
●
Do not attempt to make measurements in the presence of
flammable gasses. Otherwise, th e use of the instrume nt may cause
sparking, which can lead to an explosion.
● N ev er attempt to use th e in str ume nt if its sur fa c e or yo ur ha n d is wet.
●
Do not exc eed th e maximum a llowa ble in p ut of any me asu ring range.
●
Neve r open th e bat tery co mp artment c over du rin g a meas urement.
●
Neve r attempt to make any measurements if t he clamp sensor an d /
or the instrument has any structural abnormality, such as a crack,
or if the cover is not securely attached.
●
Do not measure AC currents.
●
The instrument should be used only in its intended applications or
conditions. Otherwise, safety functions equipped with the
in st ru ment do not wo rk, and ins tr ument da ma ge or se riou s p ers ona l
injury may be caused.
●
Keep your hands and fingers behind the safety barrier on clamp
sensor during a measurement.
#WARNING
●
Never attempt to make any measurements if any abnormal
conditions, such as a broken cover or exposed metal parts are
present on the instrument and clamp sensor.
● Do not install substitute parts or make any modifications to the
instru me n t . R e t u r n t h e i n s t r u m e n t to you r l o c a l K YO R I T S U distr i bu to r
for repair or re-calibration in case of suspected faulty operation.
●
Do not try to replace batteries if the surface of the instrument is wet.
●
Ensure that the Clamp sensor is disconnected from the object
u n d e r test, a nd t h at th e in stru m e nt is p owere d of f w h e n openin g t h e
battery compartment cover for battery replacement.
● Ra dio w aves at Blu etooth com mu nication may affect t he op eratio ns of

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.
