15.14.2 Remove Adjustment Screws

To remove adjustment screws, do the following:

1. Remove SPM head and disconnect the scanner body from the Small Sample base by pulling

its cable connector straight up. Hold the scanner body firmly in your hand.

2. Gently turn each screw to check for resistance. Turn counterclockwise until backed out of its

screw hole. If resistance is experienced in turning the screw, stop, rotate briefly in the

opposite direction, then retry. If resistance is experienced on later-model scanners, loosen the

setscrew which applies pressure to the plastic bushing (see diagram above), then try again.

3. If screws are frozen (i.e., cannot be rotated at all), DO NOT attempt to force them. Return the

entire scanner body and screws to Veeco for repair.

15.14.3 Inspect for Physical Damage

Adjustment screws are made of hardened stainless steel; threaded inserts are made of a much softer

brass. If a screw becomes fouled with hard grit it may bind against the threaded insert. If the bound

adjustment screw is forcefully rotated, the screw will almost always destroy the brass insert:

threaded inserts may become cross-threaded, or stripped entirely of threads. If this occurs, they will

have to be pressed out and replaced; return to Veeco for repair.

1. Once screws are removed from the scanner body, they may be washed using methanol. Do

not use strong solvents such as methyl chloride, MEK, benzene, etc. Use a fine brush or swab

to remove grit from between threads and shoulder. Observe caution around rubberized knob

surfaces; certain solvents may dissolve them! Be sure to remove all grit from surfaces; air

dry.

CAUTION: Do NOT splash solvent on the scanner tube or wiring at

the center of the scanner body—certain components

(e.g., wiring insulation) may be dissolved, causing

scanner failure!

ATTENTION: Ne pas éclabousser le tube en céramique piézo-

électrique ou le montage à l’intérieur du tube avec un

solvant. Certains composants pourraient être dissous,

entraînant une défaillance du tube.

VORSICHT: Verwenden Sie keine Lösungsmittel auf dem Scanner-

Röhrchen oder den Kabelanschlüssen am Piezo -

manche Komponenten (z.B. Isolation der

Anschlußdrähte) könnten sich auﬂösen und eine

Fehlfunktion des Scanners nach sich ziehen.
