    The 5µV offset can introduce an error into low power measurements with low sensitivity detectors. It is essential to use the zero offset to re-zero the MAESTRO before making a measurement in these conditions. It is always good practice to use the zero offset.

    MAESTRO user manual Revision 9.9 2.4.2. Set measure Options in the Set measure menu define user-adjustable measured data parameters. The button Wavelength can be used to change it in order to set it to the wavelength at which the detector is used. The button Range allows you to adjust the scale in order to obtain the best possible resolution.

  • Page 29: Figure 17. Wavelength Menu Windows

    MAESTRO user manual Revision 9.9 Wavelength The Wavelength button is used to select the proper wavelength at which the detector is used. It applies a correction to adjust for the variation in responsivity at different wavelengths. Pre-programmed wavelength correction factors dedicated to each detector head are available and automatically loaded from the detector EEPROM, for version 5 and higher detector heads.

  • Page 30: Figure 18. Popup Window To Enter A User-Defined Wavelength

    When the wavelength is set, touch the OK button to save the changes or touch the X button to ignore the changes. The MAESTRO only allows you to choose values that fall within the detector's range. If you enter an invalid value, a menu pops up to signal the error, and the MAESTRO automatically selects the default value which is the wavelength used for calibration at Gentec-EO during manufacturing or subsequent service.

  • Page 31: Figure 19. Range Menu Window

    To be sure to measure lower energies, set the scale manually to the lowest level and set the autoscale by pressing the Auto button. The MAESTRO will autoscale to the best scale. In this case, the pulses that saturated the scale while the autoscale was searching for the best scale will be invalid.

  • Page 40: Figure 27. Digital Needle Display

    MAESTRO user manual Revision 9.9 Needle display When you select 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.

  • Page 41: Figure 28. 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.

  • Page 42: Figure 29. Statistics Display

    You must understand your sample size well enough to know if this additional digit is significant. The MAESTRO uses default sample parameters unless you set them yourself. Touch the settings button to access the Statistics settings to set up the data sampling parameters for calculating the statistics. Use the defaults or select your own duration sample period to do the statistics.

  • Page 43: Figure 30. Statistics Settings Popup Window

    Figure 30. Statistics settings popup window You can set the MAESTRO either to calculate the statistics for a single sample and stop or to repeat continuously. Take data for a few seconds or a few days. You have the flexibility to handle any application, from analyzing a single short pulse with high resolution to sampling performance over a period of months.
