Usage Notes
WARNING
Do not allow the instrument to get wet, and do not take measurements with wet
hands. This may cause an electric shock.
To prevent electric shock, when measuring the voltage of a power line use a
test lead that satises the following criteria:
• Conforms to safety standards IEC61010 or EN61010
• Of measurement category III or IV
• Its rated voltage is higher than the voltage to be measured
The optional test leads for this instrument conform to the safety standard
EN61010. Use a test lead in accordance with its dened measurement category
and rated voltage.
CAUTION
Do not drop the instrument or subject it to excessive mechanical shock. Doing so
may damage the surfaces at the tips of the clamp sensor’s jaws, adversely affecting
measurement.
