The DO5000 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 DO5000 may be remotely controlled. 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 DO5000 will even calculate cable lengths in ohms/metre.
