The Giotto's microcomputer stores various data, including those relative to the number of lamp strikes. This infor-
mation is important because needless lamp strikes causes stress to materials and components, so can contribute
to reducing lamp life. To know how many times a lamp has been ignited:
1.
Connect Giotto Spot to the power supply, wait till it has completed reset operations and “DMX signal” appears on
the display.
2.
Use the UP/DOWN keys to find the ““Lmp_st” menu. The number of lamp strikes will be displayed automatically.

of actual strikes for the lamp about to be installed.
To reset the meter, proceed as follows:
1.
Connect Giotto Spot to the power supply, wait till it has completed reset operations and “DMX signal” appears on
the display.
2.
Use the UP/DOWN keys to find the ““Lmp_st” menu.
3.
Press ENTER to confirm. The message on the display will start to flash.
4.

3.10 Pan/ Tilt movement resolution
This function allows to define the movement resolution (16 or 8 bit). The difference is in the number of steps in
which the range of head movement is divided. In 16-bit mode, 540° of Pan and 240° of Tilt are divided into 65,536
steps, ensuring very smooth precision even at very low speeds. In 8-bit mode, the number of steps is 256, which
nevertheless allow precise movements.
