(1) U liniyadagi har qanday simlarning fazada yoki fazadan tashqarida ekanligini oʻlchash uchun past kuchlanishli yadro fazasini oʻlchashda foydalanish mumkin. Muayyan usul: erdan izolyatsiya qilingan ob'ektda turing, har bir qo'lda sinov qalamini ushlab turing, so'ngra sinovdan o'tadigan ikkita simni sinab ko'ring. Agar ikkita sinov qalamlari yorqin porlasa, ikkita sim bir-biridan farq qiladi. Aksincha, u xuddi shu fazada bo'lib, sinov qalamidagi neon lampochkaning ikkita qutbi orasidagi kuchlanish farqi uning yorug'lik intensivligiga mutanosib bo'lishi printsipi bilan baholanadi.
(2) U o'zgaruvchan tok va to'g'ridan-to'g'ri oqimni ajratish uchun ishlatilishi mumkin. Sinov ruchkasi bilan sinovdan o'tkazilayotganda, sinov ruchkasi neon lampochkasidagi ikkala qutb yonib tursa, bu o'zgaruvchan tok; agar ikkita qutbdan faqat bittasi porlasa, u to'g'ridan-to'g'ri oqimdir.
(3) To'g'ridan-to'g'ri oqimning musbat va salbiy qutblari hukm qilinishi mumkin. Sinov qilish uchun sinov ruchkasini doimiy oqim pallasiga ulang, yonayotgan neon lampochka musbat qutb, yorug'lik bo'lmagan -chiroq qutb esa salbiy qutbdir.
(4) It can be used to judge whether the DC is grounded. In the DC system with insulation to the ground, you can stand on the ground and use the test pen to contact the positive or negative pole of the DC system. If the neon bulb of the test pen does not light up, there is no grounding phenomenon. If the neon bulb is bright, it means that there is a grounding phenomenon, and if the neon bulb is bright, it means that the positive electrode is grounded. If it shines on the finger end, it is the negative ground. However, it must be pointed out that in a DC system with a grounding monitoring relay, this method cannot be used to determine whether the DC system is grounded.
