DIAMETER ADJUSTMENT OF TD1P INDICATOR
1. Insert and lock the indicator in the indicator holder by means of the 2 mm hexagonal-
end wrench (see Fig. 4) at a 7 mm “A” dimension.
2. Loosen the ring nut “1” by means of a 16mm A/F or with a 2mm hexagonal wrench
(see Fig. 5). Turn the handle clockwise so as to visualize zero on the display (see
Fig. 6).
3. Manually lock ring nut “1” so as to obtain a friction movement of the indicator holder.
4. Screw the contacts by means of the relevant wrench (see CONTACTS TABLE), in
order to bring them inside the nosepiece (see Fig. 1).
5. Unscrew the contact “T1” and, inserting the plug gauge in the master, check for a
shift of + 50 µm on the display (see Fig. 7).
6. Firmly holding the indicator turn the handle clockwise until – 50 µm is visualized by
the display (see Fig. 8).
7. Repeatedly extract and insert the bore gauge in the master unscrewing contact
“T2” each time, until the value ZERO is displayed.
In this way the excursion for each contact is 50 µm (equal to a 100 µm application
range). If the application range defined on the TECHNICAL TABLE has not been
reached, repeat steps 5 – 6 – 7 until its achievement.
8. Unscrew the plastic plug from the upper part of the indicator, and set the indicator
pointer to ZERO by means of the mechanical potentiometer (see Fig. 9). It is possible
to operate on the whole display range (± 50 µm).
Replace the plastic plug.
