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.

2.0 Declaration of Conformity

The 3M™ Wrist Strap Tester 746 is in conformity with the regulations of the EMC-directive 89/336/EWG.

The following standards have been taken into account while designing and manufacturing the instrument:

EN 60204-1/85

EN 60204-1/91 EN 61010 (Safety) EN 50082-1/92 EN 50082-2/92

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 kΩ 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.
