MODEL WBT-02 WRIST STRAP TESTER
INSTRUCTIONS FOR USE
1.Wrist strap testing
Ensure Wrist Strap is making good connection to the skin (this is usually achieved by
wearing the strap so that the stud is on the inside of the arm, as this area will have
less hair). Connect one end of Wrist Strap Cable to the Strap and the other to the
tester using the most suitable connector.
Hold the tester with Wrist Strap hand and push the touch plate with a finger from the
other hand. A green light and tone should be obtained, indicating a pass.
2. System Testing
Ensure Wrist Strap is making good connection to the skin (as above). Connect
ground connection to the most suitable connector on the tester. Hold tester in Wrist
Strap hand and push the touch plate with a finger from the other hand. A Green light
and pulsing tone should be obtained, indicating a Pass. A hi-fail (Red LED) indicates
a resistance greater than 35 Meg-Ohms in the strap or system and a lo-fail (Red
LED) indicates a resistance lower than 900 K-Ohms. In either case, the faulty
component can be isolated by testing individually between the touch plate and any
of the connectors on the tester. Remember that different people show a wide
variation in body resistance. If a hi-fail is caused because of this, try moving the
position of the strap to obtain better contact.
