2.4.3.4 Needle display
When you select the Needle, a graphical interface shows a real-time digital needle. The deflection of the
digital needle is proportional to the real-time measurement. The 0 is on the left-hand side of the needle,
whereas the range’s maximum value is on the right-hand side of the needle.. The numerical value of the
real-time measurement is also displayed above the digital needle. The 15 Hz refresh rate makes it an
excellent tool for laser tuning and alignment.

2.4.3.5 Averaging display
The averaging display is a bar graph that presents the statistics of a set of measures as a function of
time. The MAESTRO measures a series of data during a user-defined period of time. Each bar
represents the maximum, average, and minimum values of the measured data. The top of the white bar
represents the minimum value while the top of the blue bar represents the maximum value. The yellow
line represents the average value for each set of bars. This allows you to quickly evaluate the trends of
the average, maximum, and minimum values in time. You can change the sampling period by touching
the Settings button . Just touch the edit button to change the period, in seconds. If you enter
an incorrect value, an error popup window will prompt you to change it to a valid value between 1 and 120
seconds. When the averaging period is set, touch the OK button to save the changes or touch the
cancel button to ignore the changes. Statistics always run in the background in this mode. This
mode is a real time average of a group of data defined in the data sampling setting.
