3.1.3 Function Keys and Modes (continued)
There are four main operating modes, three of which
are for testing; and the fourth, for selecting options
(see displays opposite).
Once programmed to a test mode, the instrument
automatically determines the correct algorithms and
processing routines from the optical characteristics
(signature) of the inserted tube.
IMPORTANT: Before patient hematology tests,
the operator can program a sex-specific adult
normal range or pediatric normal range from a
menu of 12 range selections. If the operator fails
to select a specific normal range, test results will
appear on bar graphs showing adult male and
female normal ranges.
The OPTIONS MODE is for previewing the display
languages, setting the calendar clock and print
format and identifying the installed software
cartridge. The baud rate option function is for
computer interfacing.
3.1.4 Transport Mechanism
The tube loading platform (Figure 3-6) is designed
so that an inserted tube will roll unaided into a slot
and down into the transport carriage. Subsequently,
the tube is colleted or clamped in the carriage.
The transport mechanism (Figure 3-7) consists of a
metal carriage supported by a lead screw and guide
rod and driven by a stepper motor. The motor is
capable of a linear resolution of 0.000625 inches
per step. In conjunction with the fluoro detector
system, the transport unit functions as a precision
optical micrometer.
