MD 9070 Insulation/Continuity Digital Multimeter
Safety
5
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.
