Operation
To ensure consistent testing conditions, it is recommended to test ESD wrist straps in a setting with
controlled temperature and humidity.
a) Inserting the battery
1. Turn over the product and slide up the battery compartment cover to open.
2. Insert one 9 V block battery into the battery compartment (3) and connect the battery cable to the battery.
3. Close the battery compartment.
Follow the same steps to replace the battery. Replace the battery at least once a year.
b) Connection
1. Place the tester (2) on a dry, clean and non-sensitive surface.
2. Test the continuity of the discharge cable (6) before connection to a continuity tester to prevent damage
to the cable.
3. Fasten the ESD wrist strap (7) to your wrist.
4. Plug the banana plug on the test cable (8) into the connection jack (1).
5. Connect the discharge cable on the wrist strap to the terminal on the test cable. Ensure good contact!
c) Conducting a test
Replace the battery when the acoustic signal no longer sounds.
1. Press and hold down the button (5) using your hand.
2. The test result is indicated by means of indicator lamps (4) and an acoustic signal. See the following
table.
Indicator lamp Result Resistance Acoustic signal
Green GOOD OK 800 kΩ ≤ R ≤ 9 MΩ Yes
Red LOW Not OK R < 800 kΩ No
Red HIGH Not OK R ≥ 9 MΩ No
• If the result is not satisfactory, there may be problems with the wrist strap or the discharge cable. Conduct
suitable tests to troubleshoot.
• Caution! Too low a resistance poses a risk of personal injury.
Maintenance and cleaning
• Remove the battery before cleaning.
• Use a dry, soft and clean cloth for cleaning. Do not use any aggressive cleaning agents as these may lead
to discoloration. To prevent scratch marks, do not apply too much force on the surface during cleaning.
• You can easily remove dust using a clean, long-haired brush.
Disposal
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household waste. At
the end of its service life, dispose of the product according to the relevant statutory regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from the product.
b) (Rechargeable) batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/rechargeable
batteries. Disposing of them in the household waste is prohibited.
Contaminated (rechargeable) batteries are labelled with this symbol to indicate that disposal
in the domestic waste is forbidden. The designations for the heavy metals involved are: Cd =
Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable) batteries, e.g. below the trash
icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our stores
or wherever (rechargeable) batteries are sold.
You thus full your statutory obligations and contribute to the protection of the environment.

Intended use
Use this ESD Wrist Strap Tester to test the quality (resistance) of ESD wrist straps. ESD wrist straps prevent
electrostatic charge and formation of sparks, which can result in the destruction of highly-sensitive electronic
components and parts. The test result is immediately shown to the user by means of three indicator lamps
and an acoustic signal.
For safety and approval purposes (CE), you must not rebuild and/or modify this product. If you use the
product for purposes other than those described above, the product may be damaged. In addition, improper
