1.1Overview and Features
The CHT3548 employs the four-terminal method to highly accurately
measure the DC resistance of measurement targets including motor and
transformer windings, and welding, PC board patterns, fuses, resistors, and
materials such as conductive rubber. The instrument allows temperature
correction and so is especially suitable for measurement targets whose
resistance values change with temperature.
