LM-3 spark machine verification device

LM-3 spark tester can not only measure the sensitivity and stability of spark tester, but also increase the function of voltage test
Completely covered & rdquo; Manual breakdown device & rdquo; And & rdquo; High voltage meter & rdquo; The function of
The LM-3 is equipped with a high voltage input
A multi-function indicator; It can display not only the short-circuit steady-state current, but also the output voltage of the spark tester
The verification personnel only need to use this instrument to the work site to complete the three routinely checked electrical parameters of the spark tester at one time
The main features of LM-3 tester are as follows: ① its own power supply
② Luggage box structure, light weight, can be carried or pulled
③ Spark tester capable of detecting AC and DC ④ Equipped with multi-function indicator, the maximum measuring voltage is 30KV, and the accuracy grade is & plusmn; 1% ⑤ the meter has a scale of 0
6ua for measuring the sensitivity of spark machine
⑥ Built in 500pf capacitor is used to test the stability of spark machine
⑦ Equipped with external switch for remote operation to improve personal safety
⑧ The distance between electrodes is 0
25 & plusmn; 0
05mm is easy to adjust and measure, with scale indication ⑨ the time when the tip of the needle passes over the flat plate depends on the type of spark tester to be tested: 0
005 s for DC spark tester and 0
025 s for AC Spark Tester
⑩ It can not only test the minimum sensitivity of 600ua under 3KV voltage, but also test the stability under 30KV
It is equipped with a counter to record the breakdown times of the spark machine
