Duel Footwear/Wrist Strap Tester:
Model GTS 900
The GTS 900 combo tester is a three-state touch tester
designed for fast and accurate testing of ESD ground de-
vices. The GTS 900 incorporates a unique dual test cir-
cuit which eliminates the need for separate wrist-strap
and foot grounder testers which saves money and space.
This tester fully supports the “Compliance Verification
Plan” requirements as stated in the ANSI ESD S20.20.
Reliable, Repeatable Results
Accuracy and reliability are key strengths of the GTS 900.
Test parameters are standard but can be adjusted to
match your own specifications. Wrist-strap testing is set
with the ideal 750 kilohm-10 megohm circuit and a 750
kilogm-100 megohm circuit for accurate testing of foot
grounders. False alarms disappear and adjustments are
not necessary.
Features include:
 Combination Wrist Strap/footwear testing
 Wrist Strap Range 750 kilohm –10 megohm
 Footwear Range 750 kilohm - 100 megohm*
 Low and High failure alarm modes
 Split footplate design

Testing
The GTS900 safely tests footwear and wrist straps for
proper ESD protection.
Wrist Strap Testing
1. While wearing wrist strap, plug banana plug end of cord
in the jack labeled “RIGHT WRIST STRAP”
2. Turn the selective switch located in the top center of the
monitor to the right labeled “WRIST STRAP”.
3. Press the test button and hold for 2-3 seconds.
4. The green LED labeled “PASS” indicates that the wrist
strap and cord are functioning properly.
5. If either the red LED “LOW” or the red LED “HIGH” light
and audible alarm sound, then check the wrist strap and
cord set immediately.
Footwear Testing
For the following testing, one must be wearing foot ground-
ing ESD protection. The GTS 900’s dual footwear sensors
allows for testing of each foot independently. The left foot
ESD protection is indicated with the LED lights on the left
side and the right foot is indicated on the right side of the
monitor.
