Description

Per EN 61340-5-1, test equipment is required to enact the

Compliance Verification Plan Requirement. Wrist Straps

are to be tested while worn per EN 61340-5-1 Clause A.1.

Test equipment shall be selected to make measurements of

appropriate properties of the technical requirements that are

incorporated into the ESD program plan. The Wrist Strap

Tester can be used to fulfill ANSI/ESD S1.1, "The wrist strap

system should be tested daily to ensure proper electrical

value" (Annex A3). Being a portable battery powered tool,

it is perfect for small labs or for a supervisor to spotcheck

workers and/or ensure compliance.

The Portable Wrist Strap Tester is a battery operated "on

demand" wrist strap tester. When the wearer of a wrist strap

plugs in their coiled cord and pushes the metallic electrode

of the Portable Wrist Strap Tester, a path for current flow is

completed from the wearer's skin, through the wrist strap.

This action will cause the green "test good" LED to illuminate

as long as the resistance of the circuit path is between 750

kilohms and 35 megohms. This meets the required limits

of ANSI/ESD S20.20 and ANSI/ESD S1.1 tested per ESD

TR53.

Installation

Open the Wrist Strap Tester's battery compartment and

install the included 9V battery. If desired, use the included

hook and loop fastener strip to mount the tester to a wall or

worksurface.

NOTE: The low battery indicator flashes briefly every time

the unit is used. Replace the battery once the indicator

becomes constant during testing.

Operation

1. Fit the wristband snugly onto your wrist.

2. Snap the coiled cord to the wristband.

3. Plug the coiled cord into the Portable Wrist Strap

Tester's banana jack.

4. Push and hold the test button until the test results are

displayed.

5. An audible alarm will sound if the test fails. Verify

that your wrist strap is being worn correctly or needs

to be replaced. If your test result fails high, try applying

an approved dissipative hand lotion such as Reztore™

ESD Hand Lotion to your wrist.
