CT4656 High Speed High Precision DC Resistance Meter
CT4656 High Speed High Precision DC Resistance Meter
CT4656/CT4653 Precision DC Resistance Tester is one of the highest-precision DC resistance testers in the industry.
CT4656 dc resistance tester is 6 1/2 and 1.200,000 display, the minimum resolution can measure 0.01μΩ. Its basic accuracy of 0.01% is quite fit in the inverter motor coil inspection and other fields requiring high-resolution resistance measurement.
The CT4656 features high-speed test cable anomaly detection and extremely short measurement cycles, with a maximum sorting speed of 2.2 mS, ensuring high-speed and reliable sorting every time.
CT4653 is a compact version of CT4556; CT4656 is high configuration with a higher price.
