WARNING
● Never make measurement on a circuit above 600V AC.
● Do not use the instrument in an atmosphere where any flammable or ex-
plosive gas is present.
● Do not attempt to make measurement in the presence of flammable gas-
ses, fumes, vapor or dust. Otherwise, the use of the instrument may cause
sparking, which can lead to an explosion.
● Avoid using the instrument if it has been exposed to rain or moisture or if
your hands are wet.
● Do not exceed the maximum allowabIe input of any measurement range.
● Never open the battery compartment cover when making measurement.
● Do not use the instrument if there is any damage to the casing or when the
casing is removed.
● Do not install substitute parts or make any modification to the instrument.
Return the instrument to Yokogawa M&C or your distributor for repair or
re-calibration.
● Always switch off the instrument before opening the battery compartment
cover for battery replacement.
WARNING
To avoid damage to the instrument or electric shock!
The restrictions on the maximum voltage level for which the CL360 testers
can be used, depend on the over-voltage categories specified by the safety
standards. These category specifications are formulated to protect operators
against transient impulse voltage in power lines.

    To eliminate these superimposed components and measure only in the fundamental fre- quency, Model CL360 has a high-cut filter circuit, which can be activated by setting the frequency selector switch to the 50/60Hz position.
