1) If the green"GOOD"lam lights up and an audible signal can be heard,it shows that grounding system is safe and wrist strap is in normal condition.
2) If the red"LOW"lamp lights up,you must check the resistance of wrist strap grounding wire.If it is lower than 800KΩ,on special situation,it may have an influence on human body.
3) If the red"HIGH"lamp lights up,first,check wrist strap to make sure it contacts wrist firmly.Then,check the resistance of wrist strap grounding wire.If the resistance is higher than 9MΩ,the anti-static effect will turn feeble and even lose it anti-static ability.
LO(RED)   R<800KΩ
GOOD      800KΩ ≤R≤9 MΩ
