INSTALLATION GUIDE

1. Select a suitable site near an AC power outlet if adapter is to be used. If outlet is unavailable, use 9-

volt alkaline battery. Do not use both, as the battery may overheat.

2. If testing heel grounders, select location for foot plate.

3. If wall-mounting, select a location approximately five feet up from the floor. Before mounting, it is

recommended to plug the footplate lead into the meter to ensure there is enough wire available to

reach tester.

4. The meter can be attached to a wall, work surface, or stand using two adhesive-backed hook and

loop strips provided.

OPERATION

It is important to test wrist straps and footwear daily to ensure their proper function and to minimize

charge generation on the human body, which may cause damage to integrated circuits. Wrist straps and

heel grounders are the primary means by which electrical charges are drained from the body. Too fast a

drain will cause sparking, field generation, and failures. Too low an electrical path can cause electrical

shock. Too high an electrical path can cause integrated circuit damage. To adapt to ISO certification, the

results should be recorded and monitored.

Wrist Straps

The 780/781 Economy Combo Tester will verify that there is a safe and continuous electrical path

between the user, wrist strap and the ground cord. When using the meter for wrist strap testing or

monitoring, the following is suggested:

1. Position the selector switch located on the front of the meter into the wrist strap position.

2. Put the wrist strap on with the ground cord attached. Be sure the strap is in snug contact with the

wrist. Dry skin, hair, or foreign contaminants may cause failures for well functioning wrist straps that

are within specification.

3. Insert the end of the ground cord into the wrist jack located on the front of the Combo Tester.

4. Press and hold test button until the LED illuminates.

5. If the green “OK” LED illuminates, the wrist strap is functioning within the resistance specification

range and therefore may be used while handling static-sensitive devices.

6. If the red “High Warning” or red “Low Warning” LED illuminates and the buzzer activates, the

worker must test the wrist strap cord immediately. To test a faulty cord, leave the cord plugged into

the meter and detach the wrist cord from the strap. Press the wrist strap metal snap-end of the cord

against the metal test button, avoiding skin contact. If the cord tests fail, replace the cord.

7. If the cord passes, tighten the band cuff around wrist and retest using the cord. If it continues to fail,

apply ESD hand lotion to wrist area and repeat test. Replace wristband if failure continues.

Footwear

1. Position the footplate on the floor directly in front of the Combo Tester. Check to ensure the plate

does not slide when the meter is being used.

2. Insert the 3.5mm stereo plug into socket marked “Heel Plate” on the base of the meter.

3. Position the selector switch on the front of the meter to the “Dual Heel Foot Plate” position.

4. Stand on the foot plate making sure that each foot is aligned on the left or right stainless steel pad.

5. Press and hold test button until an LED illuminates.

6. If the green “OK” LED illuminates, the ESD shoes or heel grounders are functioning within

specifications.

7. If either of the “Low Warning” or “High Warning” red LEDs illuminate accompanied by the activation

of the buzzer for either foot, then the user should check the shoe or heel grounder. Check heel

grounder for good skin contact and dirt contamination.

Wrist Straps & Footwear

The ACL 780 Economy Combo Tester will test both feet and wrist strap simultaneously. If there is a

failure, the meter defaults in the following order: right foot, left foot, wrist.

1. Position the selector switch between the wrist and heel positions, in the “Wrist/Foot” position.

2. Position the foot plate on the floor directly in front of the Combo Tester. Check to ensure the plate

does not slide when the meter is being used.

3. Insert the 3.5mm stereo plug into socket marked “Heel Plate” on the base of the meter.

4. Stand on the foot plate making sure that each foot is aligned on the left or right stainless steel pad.

5. Put the wrist strap on with the ground cord attached. Be sure the strap is in snug contact with the

wrist. Dry skin, hair, or foreign contaminants may cause failures for functioning wrist straps that are

within specification.

6. Insert the end of the wrist strap’s ground cord into the wrist jack located on the front of the Combo

Tester.

7. Press and hold the metal test button until an LED illuminates.

8. If the green “OK” LED illuminates, then the ESD shoes or heel grounders and wrist strap are

functioning within specifications.

9. If there is a failure, the meter defaults in the following order: right foot, left foot, wrist. If either of

the “Low Warning” or “High Warning” red LEDs glow accompanied by the activation of the buzzer

for either foot, then the user should check the shoe or heel grounder. Check heel grounder for good

skin contact and dirt contamination.

10. If either red “High Warning” or red “Low Warning” LED illuminates and the buzzer activates, the user

must test the wrist strap cord immediately. To test a faulty cord, leave the cord plugged into the

meter and detach the wrist cord from the strap. Press the wrist strap metal snap-end of the cord

against the test button, avoiding skin contact. If the cord tests fail, replace the cord.

11. If the cord passes, tighten the band cuff around wrist and retest using the cord. If it continues to fail,

apply ESD hand lotion to wrist area and repeat test. Replace wristband if failure continues.

TESTER ADJUSTMENTS

The ACL 780/781 Economy Combo Tester is calibrated to NIST-traceable standards.

The tester can be adjusted for various electrical resistances by opening the meter case and pressing the

dipswitches corresponding to the desired test ranges. These resistance ranges depend on what test

standard (i.e. EOS, CECC) the user follows or the requirements set by the user’s company. The user must

know what resistance range values are acceptable for their wrist straps, shoes, and heal grounders. The

ACL 780/781 Economy Combo Tester comes preset to test limits and are represented in bold.

CALIBRATION CHECK

The ACL 780/781 Economy Combo Tester can be adjusted to various electrical resistance specifications

(limits) depending on what test standard (i.e. ESDA for US and CECC for Europe) the user follows or what

a company requires. To change settings, open the ACL 780/781 Economy Combo Tester and adjust the

dip-switches to desired resistance value. (See below for values.)

If calibration traceable to NIST is desired, send to the ACL Meter Department in order to determine and

trace accuracy. Remember the ACL 780/781 Economy Combo Tester cannot be calibrated. The meter’s

accuracy can only be checked. The meter has resistor and capacitor on the circuit board. Every time the

tester is used, it self-calibrates against this 1% resistor.

1. Purchase 1% resistors on each side of the resistance value that is set in the meter. Factory

settings (in bold) require the following resistors.

a. Foot Low (.75M) 675k & 825k

b. Wrist Low (.75M) 675k & 825k

c. Foot High (100M) 90M & 110M

d. Wrist High (10M) 9M & 11M

2. Solder, clip or twist wires to both ends of the resistors.

a. Attach one end of the resistor to the stainless steel button on the front of the meter

using an alligator clip and piece of aluminum tape. Alternatively, the banana plug can

be held to the button.

b. Attach the other end of the resistor to the receptacle that is being tested using the

appropriate plug attachment: banana plug or stereo plug for wrist, stereo plug for

testing footplate. When the feet are checked, both the right and left leg of the circuit

must have a load on the wire. If not, the unloaded leg will buzz. To accomplish this, a

stereo plug with two pigtail wires must be used. Each of these two wires must have a

resistance load on one end. The other end must be attached to the button using an

alligator clip and piece of aluminum tape or help to the button.

3. To begin test:

a. Position selector switch to “Wrist”setting when testing the wrist limits or the “Foot”

setting when testing the foot limits. Remember when testing feet a stereo plug is

inserted into the jack that usually has the foot plate plug inserted. The other end has the

resistor attached.

b. When testing wrist limits, plug resistor in wrist strap plug-in. When testing foot limits,

insert two resistors into the plug-in jack usually used for the foot plate.

4. Press the test button and compare to the resistance range to be calibrated.

5. Release the test button and compare the pass or fail response to limits being tested.

6. Since the meter is self-calibrating and self-zoning there is no adjustment necessary.

CALIBRATION USING THE ACL 9500 CALIBRATION BOX

The unit comes with two cables: one single line banana-to-banana wire, and one split wire with a monaural

termination on one end and stackable banana plugs at the Y end. When using the spit-cable, stack the banana

plugs into each other, so it can plug into the same resister.

TO TEST WRIST STRAP FOR A PASS

1. Position the selector switch on the combo tester to “WRIST STRAP”.

2. With the single wire cable, connect one end of the cable into the wrist jack on tester and the other end

into the resister rated below the desired limit. Example, if 10v is the tester’s set max limit, the red cable

plugs into the resister marked “9M OK”.

3. With the Y-cable, connect the stacked end of the Y-cable to the common point banana jack labeled "To

Push" on the ACL 9500 calibration box. Use the single-wire end of the Y-cable to make contact with the

button on the meter. The cable needs to make contact with the button as it is being depressed.

4. Press the power button on the meter (making sure that the wire is making contact with the button) and

observe the LED lights on tester. Green is pass. Red is Fail.
