MD 9070 Insulation/Continuity Digital Multimeter Safety
WARNING
To reduce the risk of fire or electric shock, do not expose this product to rain or moisture.
To avoid electrical shock hazard, observe the proper safety precautions when working
with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential
shock hazard to the user. Do not touch test lead tips or the circuit being tested while
power is applied to the circuit being measured. Keep your fingers behind the finger
guards of the test leads during measurement. Inspect test leads, connectors, and
probes for damaged insulation or exposed metal before using the instrument. If any
defects are found, replace them immediately. Never attempt a voltage measurement
with the test lead inserted into the /mA or input jack that is available. Only
replace the blown fuse with the proper rating as specified in this manual. Only use the
Test Probe Assemblies provided with the equipment or UL Listed Probe Assemblies
with same rating or better. IEC 61010-031 requires exposed conductive test probe tips
to be ≤ 4 mm for CAT III & CAT IV ratings. It is commonly achieved by permanently
over-molded plastic shrouds, or by detachable Cap shrouds for interchangeable
between CAT II ratings. Refer to the category markings on your probe assemblies as
well as on the add-on accessories (like Caps or Clips), if any, for applicable rating
changes.
CAUTION
Disconnect the test leads from the test points before changing functions. Always set the
instrument to the highest range and work downward for an unknown value when using
manual ranging mode.
