The
AT-S-250 Wrist Strap Tester
gives technicians a quick quality check for your ESD wrist straps.
Fabricated in a durable,
ESD-safe plastic housing, the AT-S-250
Tester
is a non-complicated, quick and
easy tester for your wrist straps. 9 volt battery is
included.
The wrist strap's
grounding cord/cable connects right
into the tester's grounding receptacle located on the back
and the band fastens comfortably to your wrist.
|
|
|
Press the large metal button and
the AT-S-250
for instant test results via 3 LED lights. If the wrist strap is good, the green
LED illuminates with an audible signal. If the wrist strap is compromised, one of the two red LED's
lights up.
A good wrist strap is
between 800K ohms and 9 Meg ohms. If the resistance is too
low (below 800K ohms), the "Low" indicator illuminates. If
the resistance is too high (above 9M ohms), the "High"
indicator light turns on. |

Background: Static is easily
generated from the mere movements of our clothing upon
surfaces or our shoes moving on the floor. Static charges
build up inside all of us.
Yes, we "store" the charge in our bodies.
Anyone who has stepped across a carpet in the winter and
touched a metal door knob is familiar with the little
jolting sensation and crackling sound that happens.
All because the charge is within you. And
this is what is called Electrostatic Discharge (ESD). |
|
|
Electrostatic Discharges can
quickly and permanently damage sensitive electronics devices
used on printed circuit boards (PCB's). An ESD-Safe
wrist strap (also called a grounding bracelet) helps prevent
static from being discharged and damaging circuits.
ESD wrist strap's fabric is
woven with conductive filaments in an elastic wrist band for
electronic techs. Connected to a grounded source, a wrist
strap's conductive fibers drain static away from a
technician. It prevents discharges and protects electronic
chips. |

Over time, grounding integrity of a wrist strap wears down from dust
build up, body oils and such. It is
important to periodically test the quality of your wrist
straps.
The AT-S-250 is your verification tool
so that resistance of your wrist strap is no lower than
800KΩ and no greater than 9MΩ. |

Quality PCB Work Requires ESD
Protection Securing your sensitive
electronic devices and components from electrostatic
discharges is not an "option" to disregard. An ESD wrist strap tester is an essential "tool"
for any engineer or technician working with printed circuit
board assemblies in today's world of micro electronics. |
