It can be set whether the runtime should begin immediately after the
start of the centrifugation run or only start counting after reaching the set
speed.
‘Timing begins at Start’: The runtime begins counting immediately after
the centrifugation run begins.
‘Timing begins at Speed’: The runtime only begins counting after
reaching the set speed.
‘Timing begins at Speed’: This is indicated on the display by the
symbol , to the left next to the time.
[RPM] key
