FAQ & Help (2/3)

6. Why the tester always emits an audible alarm during testing?
Check if the preset value of the break-over voltage has been set by mistake, view details on related page: Test with preset
value of the turn-on voltage (Page 09)

7. Can the tester use the power bank to power the device?
You can use 2.1A output power bank to power the device

8. How is the portability of the tester?
Take an example for you to understand its its portability: when you test with a surge protector in a new building, the
building is not yet powered with all plugs unpowered. WTH-CS / BT-1000V tester is powered with regular No. 5 batteries.
The battery-powered tester will not affect testing work in such situation. The weight of the tester is only 570g. It is very
convenient to carry it with you.

9. How many times can 4 AA batteries be tested?
We simulated testing in the laboratory. The break-over voltage of the tested surge protector was 620V. The test started
testing with 4 new No. 5 batteries installed until the tester showed LOBAT low voltage alarm. The following are the results
of the simulation test:
(1) On 1st day, install 4 new No.5 batteries, the display shows voltage 6.4V. After being tested 2300 times, the display
shows voltage 5.3V.
(2) On 2nd day, turn on the tester, the display shows voltage 5.6V. After being tested 2200 times, the display screen shows
voltage 4.9V.
(3) On 3rd day, turn on the tester, the display shows voltage 5.2V. After being tested 1300 times, the tester shows LOBAT,
the display shows voltage 4.6V.
Note: The quality of the battery performance will also affect the number of tests

10. Is there a tool bag for the tester?
There is no standard kit sold with the device, you can buy a mini tool bag from us, article number: XCW8205, as shown
below:
