CATIV and CAT II Measurement Locations
• Ensure the test lead shield is pressed firmly in place. Failure to use the CAT
IV shield increases arc-flash risk.
CAT II Measurement Locations
• CAT IV shields may be removed for CAT II locations. This will allow testing
on recessed conductors such as standard wall outlets. Take care not to lose
the shields.
WARNING: Test Lead category protections apply only to test leads and
should not be confused with the meter's specific CAT rating. Observe the
maximum category protection indicated on the meter the test leads are
plugged into.
CAUTION: If the test leads need to be replaced, you must use a new one
which should meet EN 61010-031 standard, rated CATIII 1000V or better.
NOTE: DL599 works with UEi ATL58 test leads, ABP3 back probes and AAC3
alligator clips.
ABP3 Back Probes screw-on to test leads, after removing CATIV shields from
test leads. Back Probes come with covers on probe tips.
