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.

SPECIFICATION
