LCR Meter

Our company puts these instruments on the market as the KC series. The KC series include LCR/Z meters equipped with a comparator for GO/NO-GO judgment and with BCD and GPIB boards and models dedicated for inductance or capacitance measurement. Also, the models featuring external communications function have the input/output isolated by photo coupler to minimize noise effect.

KC-555

KC-555

* 2 measurement frequencies (1kHz or 120Hz)
* The range and the mode can be set to either Automatic or Manual.
* Test signal level can be set to 1V, 500mV or 50mV, thereby making it possible to measure the capacity of semiconductors.
* Test time is 15ms minimum, including the calculation time for the correction of comparator.
* High/low limits can be set for GO/NO-GO judgment of both LCR and DQ.
* 4-1/2-digit display is used for both display A and B.
* Memory backup function is provided.
* RS-232C is a standard provision.
* 99 types of panel settings can be memorized.
