Shoes/Wrist Strap Tester 747
Daily inspection and recording of wrist straps and shoes testing are very
important as fundamental countermeasures against static on personnel.
A fully functional resistance tester, the 3M Shoes/Wrist Strap Tester 747
makes it possible to control both in a single unit. Use of the external data
port allows automatic recording of test results, virtually eliminating manual
recording and possible errors.
Features
• Checks personnel wearing wrist straps, ESD shoes and heel straps
against preset resistance limits.
• Actual measurements are indicated on a 3.5 digit display and by LED lamps.
• Test results available on RS-232C serial port and output jack.
• Testing data automatically recorded when utilizing the 3M
™
Data
Logging Software 747DLS.
ESD Shoe and Heel Strap Testing
• Electrical resistance of ESD shoes and heel straps are measured
and compared to preset limits.
• Set value for the upper and lower resistance limits can be varied.
Upper limit: 10 megohm, 35 megohm, or 100 megohm.
Lower limit: 100K ohm, 1.0 megohm.
• LCD display (3.5 digit) indicates actual resistance measurement value.*
• LEDs on the tester indicate Low, OK, and High test results.
• Measurement requires standing on the Shoe Testing Plate and
pressing the touch panel.
*Includes body resistance
Wrist Strap Testing
• Electrical resistance of wrist straps is measured and compared
to preset limits.
• Set value for an upper resistance limit can be varied.
(5 megohm, 10 megohm and 35 megohm).
Lower resistance limit 650K ohm preset internally.
• LCD display (3.5 digit) indicates actual resistance measurement value.*
• LEDs on the tester indicate (Low, OK and High) test results.
• Measurement requires inserting ground cord plugs into a test jack and
pressing the touch panel.
*Includes arm to wrist band contact resistance
External Output Functions
• RS-232C Serial Data Port provides resistance value and pass/fail
test result information for computer data logging. Used with 3M Data
Logging Software 747DLS.
• Open collector output configuration provides High and Low signal
levels for pass/fail test result indication. When used with an external
relay door, entries can be controlled.

Workstation Products
To help create and maintain the highest standards
of protection against ESD in the workplace, 3M
offers several options for employee training and
program development.
A two-day, intensive workshop is conducted four
times a year in Austin, Texas, as a “train-the-trainer”
or for the ESD program manager. Awareness, testing
and measuring, standards development, and much
more are covered in this course. 3M also regularly
conducts local one-day static awareness seminars for
electronics manufacturers, so contact your local 3M
representative for more information.
When employee training is needed, 3M can provide
solutions as well. As part of our product support,
3M can deliver various versions of training for your
organization, from basic to advanced. Having the
facts presented properly, in terms easily understood,
can help facilitate your ESD control program.
