Surge Arrester Counter Action Tester | XHJS401
The XHJS401 arrester counter action tester is a professional device researched and developed by our technical team to meet the actual needs of power industry users. With its elegant appearance and easy-to-carry, easy-to-operate design, it has completely replaced the outdated, heavy testing equipment and cumbersome testing procedures.
The instrument generates an 800 ~ 1000V high-voltage pulse to simulate a lightning discharge, verifying that the discharge counter of a lightning arrester operates and records correctly. The telescopic conductive rod on the head extends to the counter installation height, allowing one-hand operation without ladders or scaffolding, and the tail ground wire guarantees safe discharge after every test.
Powered by four size-1 batteries (DC 6V), the XHJS401 supports more than 2000 discharge tests per battery set. The green power light and red ready light clearly indicate the instrument state, and the test result is judged directly by whether the counter counts, making the inspection fast, intuitive and fully objective.
Applications & Target Audience: Designed for cultural relic and heritage building protection units inspecting lightning protection of ancient architecture, residential community property management companies performing annual lightning protection checks, fireworks and civil explosive warehouse operators meeting mandatory lightning protection requirements, grain reserve depots and large logistics parks, large stadiums and convention centers, and lightning protection installation and engineering companies verifying newly installed arrester counters.

One Instrument, Six Inspection Scenes
The XHJS401 adapts to every lightning protection inspection scene where arrester counters must be verified. Different sites share the same simple workflow: extend the rod, wait for the red light, touch the counter, read the result.
| Inspection Scene | Typical Installation | XHJS401 Advantage |
|---|
| Substation and distribution transformer | Arrester counters on transformer high-voltage side and busbar | Fast verification of all phases during routine preventive testing |
| Transmission and distribution line | Line arresters on poles and towers | Lightweight 780g body carried during line inspection rounds |
| Heritage and ancient buildings | Counter on the down conductor of the lightning rod system | Non-invasive check without affecting the building structure |
| Residential community | Counters on building lightning protection down conductors | Annual inspection of multiple buildings completed in one visit |
| Gas station and hazardous site | Counters on tank area and canopy lightning protection | Battery powered, no external power required in hazardous areas |
| Stadium and convention center | Counters on large roof lightning protection systems | Telescopic rod reaches high installations without heavy equipment |
Operating Steps
Insert the ground wire into the tail socket and ensure a secure connection
Extend the telescopic conductive rod on the head to a suitable length based on the counter height
Rotate the power switch 90 degrees in any direction until a distinct "click" sound is heard; the green light illuminates
Wait for the red light to turn on (approximately 3 to 5 seconds), indicating the instrument is ready
Touch the telescopic conductive rod to the test object to test the arrester counter
Repeated testing is possible without shutting down, but move the rod away from the test object during each charging cycle
After finishing, switch off the power first, then discharge the head conductive rod to the tail ground wire before storing the instrument
Maintenance & Battery Care
The device is powered by four size-1 batteries; replace them promptly when the charging time becomes longer
Always discharge the head to the tail ground wire after testing before putting the instrument away
Keep the instrument dry and clean; avoid dust and moisture entering the switch and rod joint
Store the instrument in a dry place and remove batteries if it will not be used for a long time
Check the ground wire and rod connection for firmness before each use
FAQ
Q1: What does the XHJS401 arrester counter action tester do?
It verifies whether the discharge counter of a lightning arrester operates correctly by injecting an 800 ~ 1000V high-voltage pulse that simulates a lightning discharge. If the counter counts, it is working properly; if not, the counter needs repair or replacement.
Q2: How is the test result judged?
The result is judged directly by whether the counter counts. After the red ready light turns on, touch the conductive rod to the counter terminal; the counter advancing one count means it operates correctly, giving an instant and objective verdict.
Q3: Can it be used for high-mounted counters?
Yes. The telescopic conductive rod on the head extends to match the counter installation height, and the compact body allows one-hand operation, so counters on poles, towers and roofs can be tested without ladders or scaffolding.
Q4: How many tests can it perform on one battery set?
Four size-1 batteries (DC 6V) support more than 2000 discharge tests. When the battery is low, the charging time becomes longer, and the batteries must be replaced promptly.
Q5: Is the instrument safe to operate?
Yes, when used as instructed. Always connect the tail ground wire securely before use, wait for the red ready light, and after testing switch off the power and discharge the head conductive rod to the tail ground wire before storing the instrument.
