Ref :UM-CT7-11-001 Issue : 01 Date : 28/04/2011 Page 15 of 35 6 CT7 Menu reference 6.1 One Click menu This menu is initiated by awakening the instrument; one can return to this menu from another one by pressing the joystick LEFT and selecting the first menu in the left column with the Up and DOWN positions of the joystick. 6.1.1 MEASURE At power up MEASURE is highlighted on the One Click screen: you are ready to perform a basic measurement utilizing the CART by default (the last one used if this is not the first measurement).
To initiate the measurement, you have to push the joystick straight; you have “time delay” seconds to position the instrument on the mirror before the measurement actually starts. The two following screens will show in succession. Press ENTER to go to the next measurement. Screen ONE CLICK appears and you can continue making successive measurements; you can also shift to Meas.*10 or to Low noise type of measurement by selecting the one you want with up and down strokes of the joystick. 6.1.2 Meas.*10 CT7 performs the basic measurement 10 times and displays the last one on the screen, but memorize the ten measurements (you can see this as the index has been incremented ten places).
6.1.3 Low noise CT7 performs five blank measurements then ten measurements that are averaged and the average result is shown on the screen and memorized. During the multiple measurements like Meas 10 or Low noise , during acquisition the number of current step is printed and finally the results are displayed. 6.1.4 Sleep The last place on the One Click menu is Sleep . Entering Sleep will shut down the instrument. This document is OPO property. It may not be either used or copied without authorization.
