Parameters
*
These parameters are available only on Rapidpoint 400 systems.
†
These parameters are available only on Rapidpoint 405 systems.
In addition to sensor chips, the sensor module contains:
• fluid detector chips
• a preheater chip
• an IDEE ROM chip
The Rapidpoint 400 series systems use two Hct sensors as fluid detectors.
Fluid detector 1 (FD1) is located in front of the first sensor. Fluid detector 2
(FD2) is located after the last sensor.
The fluid detector chips detect the presence and the continuity of fluids in
the system, and measure sample fluid using alternating current (AC)
conductivity. The system uses information from the detectors to monitor
and control the movement and the positioning of fluids during the system
sequences.
