ESD Wrist Strap and ESD Footwear being the front line defense against electrostatic build-up on the human body, must remain electrically perceptive for the user. Thus, it is very important to test every wrist strap and heel strap regularly. This combination Tester does the job efficiently without the hassle of juggling several gadgets.
To protect sensitive electronic components, the maximum wrist strap resistance should not be more than 10meg ohms and footwear resistance should not exceed 35meg ohms. However , a minimum resistance of 800K ohms is required as protections to wearer from dangerous level of current flow the wrist strap system.
The Combination Tester checks these parameters under actual operating conditions with the strap on the wrist and the heel strap on the foot. It clearly indicates whether or not the resistance of the wrist strap / heel strap system including the wearer is at least 800kilo ohms and not exceeding 10meg ohms/ 35 meg ohms respectively.

PROCEDURE
OPERATIONS
Power the instrument for use by opening the back cover to install a 9 volt battery.
FOR CHECKING WRIST STRAP
Connect the wrist strap cord onto the instrument with the strap on the wrist. Switch the indicator to “wrist strap” and press gently on the metal sensor. The instrument will turn on automatically when this is done and the operator can check whether the resistance of the heel strap falls within the acceptable range of between 800kilo ohms to 35 meg ohms. The GREEN LED will light up indicating a PASS.
MAINTENANCE
This is instrument is maintenance free and easy to mange. There are no service – able parts inside, only routine battery replacement as and when indication by low power indication.
To clean the instrument, use a damp cloth. Do not use any solvent based cleaning agent as it may damage the plastic case.
