How to Zero the Test Leads
 Warning
To prevent possible electrical shock, fire, or personal injury, do not use in CAT III
or CAT IV environments without the protective cap installed. The protective cap
decreases the exposed probe metal to <4 mm. This decreases the possibility of
arc flash from short circuits.
When you measure the Continuity (R
LO
) of equipotential bonding conductors and lightning
protection conductor wiring, the test leads have a small amount of inherent resistance that can
affect a measurement. Before you do a continuity test, use the zero adapter to compensate
for, or zero, the test leads. See
Figure 1.
