I. General
Personnel grounding devices such as wrist straps
and conductive footwear are the primary method
to minimize charge generation on the human
body. They must be able to drain this charge as
rapidly as it is generated.
For this reason, it is important to test wrist straps
and conductive footwear on a regular basis to
ensure they are functioning properly and that the
test results can be recorded
II. Declaration of Conformity
The 740 Wrist Strap and Shoe Tester is in
conformity with the regulations of the EMC-
