Cropico DO5002 100mA Low Current Microhmmeter

The Cropico DO5002 microhmmeter is a truly remarkable instrument and ideally suited for laboratory testing of samples, for production line testing, and with the addition of the interfaces RS232 / IEEE-488 or PLC, the DO5002 may be remotely controlled. The DO5002 is a true four wire measuring instrument eliminating the need to compensate for lead resistance. The measured value is displayed in large characters with decimal point and units kΩ, Ω, or mΩ. For maximum accuracy the measuring current may be automatically reversed and the average of measurement displayed. For measurements on unstable samples, a rolling average filter is available. Automatic temperature compensation and Hi / Lo limit permits sorting of components with the minimum of fuss. All these options are included in the basic unit as well as a data logging function which stores up to 4000 readings with date and time stamp. Statistical analysis of these values allows you to display the max / min /average values as well as peak to peak and standard deviation. The Cropico DO5002 will even calculate cable lengths in ohms/metre. The D05002 has a lower current capability than both of the other models. FEATURES True 4 terminal measurement eliminates lead resistance errors. Measuring range from 3 milli ohm to 30 kilo ohm, 10 micro ohm resolution. True zero capabilities. Digital Calibration. Automatic temperature compensation with programmable coefficients. Current range from 10 µA to 10 mA. Fast measuring capability of 50 measurements per second. Programmable measuring current 10% to 100% in 1% steps. High Accuracy 0.03%. Cable length calculations.
