Abstract
A measurement device for measuring a current calibration coefficient includes: a host computer and a current source, wherein the host computer is configured to acquire current calibration coefficients including a current calibration coefficient at a temperature Tand a current calibration coefficient at a temperature T, and transmit the current calibration coefficients to the current detection device. The current calibration coefficients are acquired by: controlling the current source to output a first current with a first specified current value to the current detection device when ambient temperature of the current detection device is at the T, calculating, according to the first specified current value and a first detected current value detected by the current detection device, a current calibration coefficient at the T, and determining, according to the current calibration coefficient at the Tand the resistance-temperature characteristic curve of the shunt, the current calibration coefficient at the T.
