The black boxes are seen as the key to discovering why the Airbus crashed May 3 six kilometers (3.7 miles) off the Russian coast with the loss of all 113 people on board.
"The equipment has been loaded on a vessel," the official from the Emergency Situations Ministry said. "Today, it will be fixed, tuned and tested."
On Saturday, recovery teams said a deep-sea search vehicle had recorded images of objects believed to be the flight recorders and other parts of the airliner.
The objects were located using the same coordinates as the radio signals presumed to be coming from the flight recorders.
Transportation Minister Igor Levitin, who is overseeing the recovery effort, said Saturday the recovery of the objects would start May 16, adding that the effort could take two or three days, depending on the weather.
He said the objects were at a depth of 496 meters (1,627 feet) and at a distance of five meters (16 feet) from each other.
The Airbus A-320 operated by Armenia's Armavia was flying from the Armenian capital, Yerevan, to Adler airport, which services the popular Russian resort of Sochi, when it came down in stormy weather.
