1.0 General
Wrist straps 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 on a
regular basis to ensure they are functioning properly, and
the test results should be recorded.

3.0 Description
The 3M™ Wrist Strap Tester 746 operates as a battery
powered tester, or additionally with an AC power supply
as backup for the battery. It is designed to be used either
as a stationary or portable piece of equipment. The 746
is supplied with a 9V alkaline battery - a power supply is
optional.
The tester has a permanent, internally set resistance range
which extends from 750 k
Ω to 10 MΩ. When tested, if the
wrist strap is within this resistance range, the green LED
will illuminate. The red LED indicates that the resistance
to ground of the tested device or system is out of range.
