The Prostat PWA-805 Wrist Strap Auditor is designed to determine the condion of a wrist strap as-

sembly. Used with the PRS-801 or PRS-812 Resistance Meters, a resistance measurement can be made

of the full assembly cu and cord, the cu only, or the cord only. This measurement will dene the

operable condion of any standard wrist strap.

A. The PWA-805 unit approximates the basic electrical measurement requirements of the ANSI/ESD

S1.1 wrist strap standard.

B. The intent of the PWA-805 is to provide the ESD auditor with a convenient xture to measure the

exact resistance characteriscs of a wrist strap, rather than generally esmate its approximate

resistance range with an indicang checker.

C. The PWA-805 will provide the four following resistance measurements:

1. Resistance of a wrist strap from the inner, middle posion of the cu to the end of the ground-

ing cord.

2. The resistance between two points on the inner surface of the cu

3. The resistance between two points on the outer surface of the cu

4. The resistance between the cord cu snap and ground connecon

A. As with any electrical device, use proper electrical precauons to avoid personnel shock.

1. The PWA-805 Wrist Strap Auditor xture operates with power input from the Resistance Meter

at 10 to 100 volts, and is capable of delivering an annoying shock to any person touching it.

2. Although the current capability is limited, a disnct HAZARD EXISTS in the person’s reacon to

the shock.

3. To avoid personnel shock, do not touch the can electrodes when power is applied to the xture



To avoid electrical shock, do not touch the xture’s

can electrodes when power is being applied.

B. The PWA-805 is designed to be used in audit environments at test voltages of 100 volts or less.

Exceeding 100 volts greatly enhances the risk of personnel shock hazards and may damage the

xture.



Operaonal test voltages should not exceed

100 volts in the audit environment.

A. Basic Descripon

The PWA-805 Wrist Strap Auditor Fixture consists of two metal cylinder electrodes mounted on a

plasc base and wired to a switch, cord connecon points and meter input receptacles.

1. The metal cylinder (can) electrodes are used to mount wrist strap cus for connuity and resis-

tance measurements.

2. A YELLOW cord receptacle allows the wrist strap grounding cord to be plugged into the xture’s

test circuit.

3. Two meter input receptacles (RED and BLACK) are provided to connect the Resistance Meter

to the xture’s test circuit. The Resistance Meter provides all resistance measurements for the

PWA-805 Auditor.

4. Two male snap posts, one 7 mm and one 4 mm, are provided for mounng the cu snap end

of the grounding cord to the xture circuit during Cord Only measurements.

5. A three posion rocker switch (BLACK) allows resistance measurements of the following wrist

strap components:

a. The Cu and Grounding Cord

b. The Cu Only

c. The Grounding Cord Only

A. General

1. This operaon will provide the four following resistance measurements:

a. Resistance of a wrist strap from the inner surface, middle posion of the cu to the end

of the grounding cord. This measurement indicates the maximum resistance between the

user and an ESD common ground point.

b. The resistance between two points on the inner surface of the cu. Properly used, this

measurement denes the connuity of the inner cu’s surface between 2 points, 180

apart.

(1) Thus, proper connecons of the cu to the wrist buckle may be conrmed.

(2) The connuity around the enre perimeter of the inner cu surface may be

conrmed.

10 Rev. A / January 1995

PWA-805 Wrist Strap Auditor Fixture

c. The resistance between two points on the outer surface of the cu. This measurement

conrms the insulave characteriscs of the cus outer surface.

d. The resistance between the ground cord’s cu snap and its connecon to ground. This

measurement performs two funcons.

(1) It allows the operator to check the ground cord for “opens”

(2) It measures the total resistance of the ground cord conductor resistor and

connecon points.

2. The following procedures require the use of the Resistance Meter. Be sure to read its Opera-

ons Manual and perform its Funconal Test prior to using.

B. Resistance Measurement of a wrist strap assembly CUFF & CORD.

1. Connect the test leads from the Resistance Meter to the PWA-805 Auditor RED and BLACK

METER receptacles.

2. Place the rocker switch in the middle CUFF & CORD posion

The LEFT can electrode in the CUFF & CORD measurement Mode is used to hold the cu me-

chanically; it is not in the measurement circuit. The RIGHT can electrode is in the measure-

ment circuit. Consequently, the inner cu surface must contact the

RIGHT can electrode to obtain an accurate measurement.

3. Mount the wrist strap cu to the PWA-805 xture as follows:

a. Loosen the adjustable RIGHT can electrode and slide it toward the LEFT can electrode.

b. Posion the inner surface of the cu buckle against the LEFT can electrode and hold it

rmly in posion with your le hand.

c. With your right hand, stretch the cu over and onto the adjustable RIGHT can electrode.

d. Slide the adjustable RIGHT can electrode toward the right side of the xture unl there are

1 to 2 pounds of tension on the wrist strap cu.

e. Tighten the RIGHT can electrodes locking screw.

4. Plug the wrist strap’s ground cord banana plug into the YELLOW CORD receptacle.

5. The wrist strap is now mounted on the PWA-80S xture. Be sure:

a. The cu is posioned smoothly on the sides of the two can electrodes

b. The ground cord is properly aached to the cu buckle

c. The ground cord banana plug is fully inserted into the YELLOW CORD receptacle.

6. Select the 10 volt posion on the Resistance Meter and push the TEST buon to obtain a resis-

tance measurement.
