POWER Parameters has released the Chroma 16502 milli-ohm meter, designed for applications including the measurement of contact resistance, resistance of high inductance components and in analyses likely to be affected by thermal electric and magnetic fields (EMFs).
A large number of resistance ranges make measurement convenient from 0mΩ-20mΩ to 200kΩ. Drive modes include positive and negative dc (suitable for high inductance devices), and positive and negative pulsed modes which assist in minimising thermal EMF effects.
A standard RS 232 interface is provided and an optional GPIB and handler interface are available. Comparator Hi/Go/Lo levels and eight sorting bin limits (set in percentage of chosen parameters) permit automatic sorting.
