* Only when suction head's vacuum negative pressure reaches to 50-80Kpa the sample can be sucked up. Otherwise the suction head won't work and sample keeps its position.When suction head works, during access process, the sample won't be dropping off.
Solutions to sample's dropping off during access? Will data be lost or cause chaoss?
* A fixed negative pressure value has been set at the vacuum negative pressure suction head, if the suction position is off center, the suction head will not be able to suck sample up and the machine will alarm.
* Just recalibrate the position and sample can be picked up, Once the sample is sucked up, it will not fall off or get lost halfway nor data chaos.
