Final testing:
After terminating the installation procedure, test the system as follows:
a) Verify that the new arm head is firmly secured to the shaft (Fig. 5-4, 5-5
and 5-6). Try to rotate the head after holding the shaft stationary. Head
should not move, if otherwise then firmly tighten the locking screw.
b) Touch with finger the sampling needle, instantly the red LED at the
bottom of arm head lights and projects a beam downwards.
c) Let few minutes pass and then touch the needle holder, it should feel
warm (heated).
d) In the program of calibration services repeat the verification of positions
and eventually correct them.
Now the new arm head has been correctly installed. Any future maintenance will
be much easier as the only part subject to wear and periodic replacement is the
"Sampling Tube with Needle Holder" P/N 08-05029-01 (Figures 5-7 & 5-11),
which also incorporates the supply voltage leads for powering the arm head
system. The "Sampling Tube with Needle Holder" kit integrates sampling needle,
needle holder, sampling tube with heating circuit and appropriate connectors.
