I bought Belkin's anti-static wristband but i must be sure it works, since sometimes people report getting units that are defective or do not work in reality.
I have laptop only. How to check if anti-static wristband works?
UPDATE: I have tested anti-static wrist strap with multimeter with resistance set on 2M and the result was 0.983
Is this normal?
Get a Van der Graaf generator and put your hand on it while you have your anti-static wrist band on (and shoes) and then get someone to go up to touch you. If they get a shock, it does not work. If your hair stands on end, that would be another sign that it does not work.
I have no idea where you could get a Van der Graaf generator, but this test should work if you manage to do so.
Use an ohmmeter or multimeter to determine if there is conductivity between the metal part of the wrist strap, and the end part where you connect it to ground. You should see some measurable resistance (indicating good conductivity) if the strap is functioning correctly. If the resistance is extremely high (or as some meters measure, infinite), then the strap is broken.
Alternatively, you can just use it as a "wire" in conjunction with something else (e.g. an LED) and determine if you can provide power through the anti-static wrist strap. If current can flow through it, it's working, since that is all the device is used for (to provide a quick path to ground for your skin).
This is only a theory, but since laptop trackpads only work with things with an electric charge (Eg, your finger), an antistatic wristband could cause it not to recognize your finger, thus proving it works. Remember, just a theory, so if it doesn't work don't blame me.
