Sandi, who joined the team after making sporadic WSBK appearances, most recently for Grillini BMW at Misano last season, enjoyed dry conditions at the Spanish track.
He was joined by Superstock riders Federico Dittadi and Lorenzo Savadori at the shakedown, where he completed 100 laps.
"The whole test has gone really well for me. It was very important to work with my new team and I'm very happy because I immediately found a good feeling with all of them,” Sandi said.
“We worked really hard on the bike here in Almeria and I think it's just going to get better and better.
“There is still a lot to do but the outcome is already very good. I'm really looking forward to next test in Phillip Island to be able to start the 2013 Superbike championship in the best possible way.”
The 2013 season begins at Phillip Island on February 24.
