Description
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
- While wearing wrist strap, plug banana plug end of cord in the jack labeled “RIGHT WRIST STRAP”
- Turn the selective switch located in the top center of the monitor to the right labeled “WRIST STRAP”.
- Press the test button and hold for 2-3
- The green LED labeled “PASS” indicates that the wrist strap and cord are functioning properly.
- 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.
- Turn the selective switch located in the top center of the monitor to left labeled “FOOTWEAR”
- Place feet onto silver sensors of platform.
- Press the test button and hold for 2-3 seconds
NOTE: Testing of footwear on both feet happen simultane- ously.
- The green LED located on the LEFT side of monitor la- beled “PASS” indicates that the LEFT foot ground is func- tioning properly.
- The green LED located on the RIGHT side of monitor la- beled “PASS” indicates that the RIGHT foot ground is functioning properly.
- If either the red LED “LOW” or the red LED “HIGH” light on the LEFT side of monitor and audible alarm sound, then check the LEFT foot ground set immediately.
- If either the red LED “LOW” or the red LED “HIGH” light on the RIGHT side of monitor and audible alarm sound, then check the RIGHT foot ground set immediately.
