ADJUSTMENT
Sysmex SF-3000 Operator's Manual -- Revised September 1995 9-1
1. INTRODUCTION
From time to time it may be necessary to adjust certain components of the SF-3000
system. The Sysmex representative will perform initial adjusting; following that, the
customer should adjust the instrument as described in the procedures provided in this
chapter.
The following adjustment procedures have been included in this chapter.
• Pneumatic pressure (2.0 kg/cm
2
)
• Main Unit pressure (0.6 kg/cm
2
)
• Main Unit pressure (0.5 kg/cm
2
)
• Main Unit vacuum (250 mm/Hg)
• LCD Contrast
2. PRESSURE/VACUUM DISPLAY
Pressure and vacuum from the Pneumatic Unit are adjusted by the Pneumatic Unit and
Main Unit to 2.0 kg/cm
2
, 0.6 kg/cm
2
, 0.5 kg/cm
2
and 250 mmHg. These pressures and
vacuum are monitored by sensors. If an error message is displayed, check the line
connections for a leak. Afterwards, display the monitored value on the LCD and adjust
the pressure or vacuum as described below.
2.1 Pneumatic Gauges
After you turn on the power and "Ready" appears on the LCD, check the pressure and
vacuum level. The gauges on the front of the Pneumatic Unit show the pressure and
vacuum. Adjustment is needed when the pressure does not conform to the requirements
below. Vacuum cannot be adjusted in the Pneumatic Unit. See page 9-5.
