16502 Digital Milliohm Meter provides a 0.001mΩ~1.9999MΩ wide measurement range with 4½ digits resolution. DC, Pulsed, and Dry-circuit test current driving modes enable the 16502 to be properly used in DC resistance measurements for various inductive components (coil, choke, and transformer winding etc.), cable, metallic contact (connector, relay switch etc.), and conductive materials. Pulsed test current output mode is used to reduce thermal EMFs affection on milliohm measurement. DC test current output mode is used to fasten measurement speed for inductive DUT. Standard RS-232 interface.
