• DO NOT USE the test leads when the internal white insulation
layer is exposed.
• DO NOT USE the test leads above maximum ratings of CAT.
Environment, voltage and current, that are indicated on the
probe and the probe tip guard cap.
• DO NOT USE the test leads without the probe tip guard cap
in CAT III and CAT IV environments.
• Probe assemblies to be used for MAINS measurements shall
be RATED as appropriate for MEASUREMENT CATEGORY
III OR IV according to IEC 61010-031 and shall have a
voltage RATING of at least the voltage of the circuit to be
measured.
• Only replace the blown fuse with the proper rating as
specified in this manual.
• Do not attempt a resistance measurement when the open
voltage is above the fuse protection rating. Suspected open
voltage can be checked with voltage function.
• Never attempt a voltage measurement with the test lead
inserted into the Ω input terminal.
• Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, or
capacitance.
