From ISS On-Orbit Status Report for 15/03/2011.
Soyuz TMA-01M Post-Undock Tests:
In a departure from the standard undock/sep/deorbit template, Soyuz TMA-01M/24S will conduct two attitude control tests shortly after physical separation (4:27 AM GMT) and before deorbit. After moving slowly away from MRM-2 (Mini Research Module-2) in the Zenith direction (–Z = straight up), the spacecraft will station-keep at a range of ~50m, and the crew will test the new RODK (Manual Attitude Control in Digital Mode) of the ship at ~4:31 AM GMT. After the test, at ~4:36 AM GMT, Soyuz will perform a 20 second separation burn (delta-V ~0.72m/sec), moving further to the ISS Zenith and then Aft. At ~4:37 AM GMT, the crew will perform the second test, this time of the ROAK (Manual Attitude Control in Analog Mode) using the new angular speed sensors (ammeters). Nominal deorbit burn is scheduled for ~7:03 AM to 7:07 AM GMT.
