Operating Procedures
4.1 STARTING ANALYZER
4.1.1 Power-On Self-Check
Actuating the POWER switch on the back of
the analyzer causes the instrument to test its
internal electronics, optics, and mechanical
systems, including the segmented LCD displays.
NOTE: Before turning power on, be sure the
loading platform is empty (tube removed) and
the platform door is closed. If the door is left
open, the self-check sequence will stop, and a
display message to close the door will appear.
During the LCD display check (Figure 4-1), verify that
all segments in all the numeral “8”s are illuminated
and that decimal points are present in all readouts
except %GRANS, %LYMPH/MONO, and PLT.
Request service in the event of a defective display.
Status messages are automatically displayed during
the startup sequence, as shown opposite.
If the SYSTEM CHECK phase fails, an alert message
will appear that flags an error condition. See
Table 4-3 for a list of startup error flags.
