  • Page 14 Safety Notes WARNING • To avoid electric shock, short circuits and damage to the instrument, disconnect the test leads from the measurement object before switching the rotary switch. • To prevent electric shock, when measuring the voltage of a power line use a test lead that satisfies the following criteria: •...
  • Page 15 Safety Notes WARNING • Installing the instrument in inappropriate locations may cause a malfunction of instrument or may give rise to an accident. Avoid the following locations: • Exposed to direct sunlight or high temperature • Exposed to corrosive or combustible gases •...
  • Page 16 Safety Notes WARNING • Since there is a risk of electric shock, check that the insulation on the test lead and flexible sensor (optional) are neither ripped nor torn, and no metal conductor inside the wire are exposed before using the instrument. If damaged, replace them with those specified by our company.
  • Page 17 Safety Notes CAUTION Do not place foreign objects between the jaw tips (or flexible loop couplings) or insert foreign objects into the gaps of the jaws (or flexible loop couplings). Doing so may worsen the performances of the sensor or interfere with clamping action.

  • Page 18: Inspection Before Measurement

    If you find any damage, contact your authorized Hioki distributor or reseller. • If damage is suspected, check the section below before contacting your authorized Hioki distributor or reseller. Check that the test lead is not broken. Replace with the specified L9208 Test Lead.

  • Page 19: Maintenance/Inspection

    Maintenance/Inspection Maintenance/Inspection Cleaning • Measurements are degraded by dirt on the mating surfaces of the jaw (or flexible loop coupling), so keep the surfaces clean by gently wiping with a soft, dry cloth. • To clean the device, wipe it gently with a soft cloth moistened with water or mild detergent.

Hindari lokasi-lokasi berikut ini: • Terpapar sinar matahari langsung atau suhu tinggi • Terpapar gas korosif atau mudah terbakar • Terpapar medan elektromagnet kuat atau muatan elektrostatis •...
  • Page 68 Catatan Keamanan PERINGATAN • Karena terdapat risiko sengatan listrik, periksa bahwa insulasi pada test lead dan sensor fleksibel (opsional) tidak terkelupas atau robek, dan tidak ada konduktor logam yang terbuka di dalam kawat sebelum menggunakan instrumen. Jika terdapat kerusakan, gantilah sesuai dengan petunjuk pengunaan dari perusahaan.
  • Page 69 Catatan Keamanan PERHATIAN Jangan letakkan benda asing di antara ujung capit (atau kopel lingkaran fleksibel) atau memasukkan benda asing ke dalam celah capit (atau kopel lingkaran fleksibel). Bila hal tersebut dilakukan, hal tersebut dapat memperburuk kinerja sensor atau mengganggu penjepitan. Kinerja buruk atau kerusakan dari kebocoran baterai dapat terjadi.

  • Page 70: Inspeksi Sebelum Pengukuran

    Ganti dengan Test Lead L9208 yang telah ditentukan. Periksa bahwa pengukuran hambatan dan uji kontinu berjalan normal. Mintalah agar distributor atau penjual Hioki resmi Anda memperbaiki instrumen. Instrumen mungkin akan memiliki tegangan lebih dari 600 V selama pengukuran hambatan atau uji kontinu.

  • Page 71: Pemeliharaan/Inspeksi

    Pemeliharaan/Inspeksi Pemeliharaan/Inspeksi Pembersihan • Pengukuran akan menurun oleh kotoran pada pertemuan permukaan capit (atau kopel lingkaran fleksibel), oleh sebab itu, jaga agar permukaan tetap bersih agar menyekanya menggunakan kain kering dan lembut. • Untuk membersihkan perangkat, seka dengan lembut menggunakan kain yang telah dibasahi air atau detergen ringan.
