CALL: A.WIHARTA 081294124885 085778084789 087784022201     Info Produk The 3237, 3238, and 3239 Digital HiTesters can perform 3.3 ms high-speed sampling, and come equipped with a comparator, external input and output, and an RS-232C interface. These three highperformance DMMs can be used not only in laboratories, but in production lines that require the minimal tact time. The 3239 includes the functions of the 3238 plus the 4-terminal resistance measurement function. All three units are designed with emphasis on measurement speed and safety. In fact, HIOKI guarantees accuracy of the 3238 and 3239 for AC voltage of 10 Hz to 300 kHz, and AC current of 10 Hz to 30 kHz. Features: Samples at rates of up to 300 samples/ sec. ( 3.3 ms/ sample) Comparator function provides high-speed pass/ fail evaluation Equipped with external input and output for sequence control Usefull Save/ Load function helps work go faster Low power resistance measurement function prevents sample deterioration True RMS value measurement Interface supports full remote operation DC V basic accuracy: ± 0.01% rdg.± 2dgt.
