Halo, Saya Pebisnis Saya mengenal produk ini dari https://www.indotrade.co.id dan saya lihat hal ini mungkin berguna untuk anda. ------------------------------------------------------- KYORITSU 4106 KYORITSU 4106 Negara Asal: Jepang Cara Pembayaran: Transfer Bank ( T/ T) Kemas & Pengiriman: 1 unit Keterangan: • High test current up to 80mA yielding resolution of 0.001© on 2© range. • Advanced Filtering method ( based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements. • Automatic and Manual selection of the Test Current Frequency in four bands ( 94/ 105/ 111/ 128Hz) . In Automatic mode, KEW 4106 will select the most suitable Frequency. • Several sub-results can be shown on the display: Resistance of the Auxiliary Earth Spikes, Frequency of Test Current, Voltage and Frequency of Interference ( noise) , Residual Resistance Rk, etc. • Warning for excessive noise and high Auxiliary Earth Spikes resistance • Large Graphic Display with backlight for readings in poorly illuminated areas. • Up to 800 measurement results can be saved in the memory and recalled on the display. • The stored results can be transferred to a PC using the " KEW Report " software and a USB adaptor ( Model 8212-USB) which are included. • Robust design with IP54 protection.
