Thông tin sản phẩm

The TERA ohmmeter TOM 374 uses the voltage measuring method, whereas a a electro field meter is used  as a measuring amplifier due to its high input resistance. Therefor high resistors up to 1014Ω can be measured with a measuring voltage of 100V and an accuracy of 5% directly against earth. Besides the connecting sockets are additional ground jacks to connect earthed measuring lines to eliminate measuring inaccuracies due to parasitary effects. To comply to standards  (IEC, EN, DIN, VDE u.a.) the demanded measuring time can be adjusted by an internal timer.

The input impedancy of the device is > 1016Ω
