Settings and Measurement

Settings and Measurement CHECKPOINT Changing the sampling interval, capture destination, or number of capture points will change the screen display of the time available for data capture, capacity available for data capture, and possible number of times of repeating. If you find that the measuring time exceeds the capacity available for data capture, either change the sampling interval or capture destination (to largecapacity USB memory). Time available for data capture ................. Indicates how long data can be captured. Capacity available for data capture ........... Indicates the capacity available for data capture with the memory size if the data capture destination is the internal flash memory or USB memory. The figure shown in brackets is the percentage of free memory space to the total memory size. Possible number of times of repeating ...... Indicates how many times data captured to the internal RAM can be saved to the save destination device if Auto Save is set to On. Beware of using this setting particularly when Repeated Capturing is set to On for the trigger (For details, see page 3-28 in the "TRIG Settings." * The time available for data capture is calculated for data up to 2GB. If the capacity of free USB memory is 2GB or more, “over” is displayed. When the time available for data capture (for 2GB) is exceeded, after the data of 2GB is captured, the capture of remaining data is automatically resumed to another file. Note that the data between the stop and resumption of the capture process is not captured when the sampling interval is too fast. (2)-6 Statistical Calculation Settings The GL900 can perform two statistical calculations. This section describes specifying the statistical calculation settings. Selection Off Average Max Min Peak RMS Description Calculation is not performed. Displays the simple average value of data being captured. Displays the maximum value of data being captured. Displays the minimum value of data being captured. Displays the peak value of data being captured. Displays the effective value of data being captured. The calculation formula is as shown below. * D : data n : number of data CHECKPOINT • The calculation results are displayed in the Digital + Statistical Calculation Display screen. Switch to the Full Channels + Statistical Calculation Display using the and keys. For details, see page 3-8. • Calculation will start upon power ON. Pressing the Start key to begin measurement will clear the calculation. • The sampling speed for calculation corresponds to the speed set in the DATA menu. However, when the sampling speed is higher than 5ms, it is set to 5ms. 3-27
