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.

Description
The 745 Wrist Strap Tester is a battery powered tester designed to be used either as a stationary
or portable piece of equipment.
The 745 has a permanent, internally set resistance range which extends from 750 kQ to 10 MQ.
If the wrist strap, when tested, 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 this range.
