The invention relates to a single-phase multi-meter-position asynchronous calibrating device. The single-phase multi-meter-position asynchronous calibrating device comprises six independent single-phase stabilization sources, six 0.05-level single-phase standard meters, six single-phase error meters, a 0.02-level single-phase standard meter, a computer and a six-meter-position rack. The single-phase multi-meter-position asynchronous calibrating device is characterized in that the six independent single-phase stabilization sources, the six 0.05-level single-phase standard meters and the six single-phase error meters are mounted on the six-meter-position rack in one-to-one correspondence mode, and each to-be-calibrated meter position is matched with one power source, one 0.05-level standard meter and one error meter and works completely independently. The single-phase multi-meter-position asynchronous calibrating device has the advantages that the meter positions can calibrate electric energy meters in different specifications independently, and flexibility requirements on time-sharing asynchronous calibration can be met.
