Portable Surge Protective Device Tester
FAQ & Help (1/3)
1. What should I do if I can't find the paper datasheets in the package?
Watchful Eye fully implements the strategy of going green with paperless data sheets. Each product is engraved with the
URL of the paperless instructions and the QR code of the website on the upper side of the product shell where the test line
socket is located. If you need paper data sheets, you can open the link and print the online data sheets.
2. What types of surge protectors can the tester detect?
Voltage-limiting surge protector, varistor MOV, switch-type surge protector, discharge tube(GDT), or hybrid surge protector
3. Which parameters are used to detect the surge protector?
The measured parameters are: break-over voltage and leakage current of voltage-limiting surge protector (MOV),
breakdown voltage of switch-type surge protector (GDT) or hybrid surge protector
4. Can the surge protector be detected when it is powered on?
A surge protector cannot be tested under the power-on condition. It’s required to disconnect the circuit breaker or air
circuit breaker at the front of the surge protector to confirm that the surge protector has been disconnected from the power
grid, or unplug the surge protector module for testing. During the test, a break-over voltage is applied to the surge
protector until it reaches the level of break-over status. If the live test is carried out, the product will be discharged to the
ground once, resulting in the risk of short-circuiting.
5. Can the tester use rechargeable batteries?
You can use 5 pieces of rechargeable batteries instead of regular No.5 batteries.
