Seaward Group USA Cropico DO5002

The model 5002 digital micro ohmmeter offers all the features of the standard DO5000 ohmmeter but with lower measuring current. The bottom two ranges are disabled in this model. The DO5002 is particularly suited to the measurement of switch contact resistances. Open circuit voltage ~ 5V dc with Limit options for 20mV and 50mV. With all the functionality of the standard DO5000 but with limited measuring current and the ability to limit the open circuit voltage to either 20mV or 50mV. This model has been primarily developed to satisfy those applications where open circuit voltage and the measuring current needs to be limited. A typical application is for the measurement of switch contact resistance to conform to standards such as NFC93050.
