REFERENCE SOURCE MODULE, ELECTRICAL AND ELECTRIC APPARATUS, REMOTE CALIBRATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reference source module used for a remote calibration technology and remote calibration which can reduce non-operating time of an electrical and electric apparatus accompanied with calibration, when a location where the electrical and electric apparatus using the reference source calibrated by a measurement standard is placed is different from a location where the measurement standard is placed.SOLUTION: A reference source module 30 is attachable/detachable to an electrical and electric apparatus 20, and includes at least one of a voltage reference source calibrated by a measurement standard and a resistance reference source. The reference source module 30 may also include: a prediction section which predicts the current value of a reference source from record of past calibration; and an insulation mechanism which maintains ambient temperature of the reference source constant.SELECTED DRAWING: Figure 1
