Test Kits for Static Control Surfaces
The 3M Test Kit 701 contains a lightweight, user-friendly megohmmeter
plus all of the components needed to make testing mats and other
surfaces simple and accurate. All of the items are packaged in a
foam-lined carrying case.
The kit meets the intent of ANSI/ESD Standard 4.1, “Worksurfaces –
Resistive Characterization,” ANSI/ESD Standard 7.1, “Floor Materials
– Resistive Characterization of Materials,” and MIL-PRF-87893,
“Workstation, Electrostatic Discharge (ESD) Control,” for auditing
purposes. The meter has separate scales and test settings for measuring
surface-to-ground and surface-to-surface resistance at two prescribed
test voltages (10 V and 100 V), and system continuity. The easy-to-read
scales are both color-coded and numbered.

Surface Resistance Meter
The SCC-625 is a wide-range, multi-scale, auto-ranging meter. It
measures resistivity per ASTM D257, resistance per EOS/ESD S11.11,
and Resistance to Ground (RTG). Appropriate for auditing static control
items. Measures conductive, dissipative and insulative items. The meter
is battery powered and simple to use. High-speed electronics provide
repeatable measurements.
Useful for audit testing required by ANSI/ESD S-20.20, EIA 625,
MIL-STD-1686.

Wrist Strap and Footwear Tester
The 3M Wrist Strap and Footwear Tester 740 is an AC-powered unit
designed to be wall-mounted in a production facility for daily testing of
employees’ static control wrist straps. Use of the optional 3M
™
Shoe
Electrode 741 attachment allows the tester to be used as a footwear
tester as well. The optional Shoe Electrode 741 is a test plate that
connects to the Wrist Strap and Footwear Tester 740. By standing
on the shoe electrode, personnel can use the wrist strap and footwear
tester to check the operation of static control footwear, heel straps
and the like. This electrode, constructed of rugged stainless steel in
a molded plastic base, must be ordered separately.
Simple to operate, the unit has several useful features and options. Red
and green LEDs give a clear “go” or “no go” indication. The user can
select any of four different resistance levels, making the tester a versatile
instrument to meet varying industry, corporate and global standards. The
unit tests the wrist band and cord while they are being worn, and can also
test each component independently to isolate an indicated fault. There
is also a digital output that can be used to interface with a computer,
automatic door lock, alarm or other control device.
The wrist strap and footwear tester comes with the base unit, output
connector, 3M Dual Lock
™
Wall-Mounting System and template, cover
for the wrist strap plug-in jack and the AC/DC transformer.
Note: The Shoe Electrode 741 is not included with the Wrist
Strap and Footwear Tester 740 and must be ordered separately.
