4-10 Maintaining the Analyzer
1. Shake off any excess water,
then install the front face on
the shaft by aligning the black
line on the front face with the
black line and the
A on the
rear face. The smaller loops
should be at the 9 and 11
o’clock positions and the
large loop should be at the 5
o’clock position.
2. Install the rotor by inserting
the drive pin (
2 ) into the hole
( 1 ) on the right side of the
front face.
3. Replace the spring ( 3 ), and
the knurled nut ( 4 ). Hand
tighten the nut.
Cleaning the Shear Valve: Step 4
Checking Analyzer Performance
Check analyzer performance by:
•
Checking saline backgrounds
•
Running a whole blood primer
•
Running controls
If controls do not recover, calibrate affected channel.
Inspecting and Cleaning the Syringe Plungers PN 067-506-01 and PN 067-
506-02
Inspect the tip of the plunger during a
saline prime.
The normal wear of the plunger tip
(sheath
1 [1000
μ
L syringe] and
sample
2
[50
μ
L syringe]) against the
syringe barrel can cause small pieces
to be detached. These small particles
appear as a gray gel at the tip of the
plunger. If this gel enters the
hydraulic system, it can cause clogs in
the analyzer. Clean if necessary.
