6) Correctly install the new "Sampling
Tube with Needle Holder" on the
arm head and firmly secure the
needle holder by tightening the
clamp screw (Figure 5-15).
7) Place the cover on the arm head
and gently push down to stop.
Ensure that the sample tube is
correctly positioned between the
metallic fin and the appropriate slot
on the rear of cover. Securely fasten
the two screws on the sides of the
cover (Figure 5-13).
NOTE:
The preceding installation procedure is
identical for both the sampling and ISE
arms (left arm and right arm in BT 3000
PLUS). To facilitate production the length of
sample tube (single plastic tube adjacent to
the electrical connector - Figure 5-12) is
identical in both the arms. It is necessary to
reduce the length of the plastic tube of left
arm head (for clinical chemistry sampling)
by about 20 centimeters prior to connecting
it to the diluter. The length of tube of right
arm head (ISE sampling arm) remains
unaltered. In the analyzers BT 1000 and BT
2000 PLUS (without ISE sampling arm) the
tube length of sampling arm head must be
reduced by 20 centimeters (Figure 5-12) as
already outlined
