8.2.1 TOOLBAR BUTTONS Starts the measurement. Permits execution with the control panel in a minimized state. Only a small stay-onthe-top display remains visible. See 8.3.2. Stops the measurement. If pressed displays all measured parameters. Captures the actual reading of the multi-meter as the global reference level (or microphone sensitivity); refer to 8.3.2 and 8.4.1 for details. Control the scale of the meter bar graph. 8.2.2 TOOLBAR DROP DOWN LISTS parameter Selects the parameter to be measured. unit Selects the measurement unit. channel Selects the input channel. integration Selects between fast (125ms) and slow (1s) integration. Not applicable to the LCR meter. 86 Chapter 8 - Multi-Meter
8.3 USING THE MULTI-METER The first application of the Multi-meter has been described in section 3.4.1 when <strong>CLIOwin</strong> was started for the first time. This was a simple generation of a 1kHz sinusoid (0dBu output level) and relative level capture with the Multi-meter. You can continue the measurement described to familiarize yourself with the instrument. Pressing the magnifier will let you inspect all the parameters that the Multi-meter measures in parallel (Fig.8.1); changing the selected parameter will bring it to the foreground; for any parameter it is possible to choose different units, for example THD can be shown in percentage or in dB; then you can select the input channel and the integration. This last parameter (integration) affects the measurement rate, since the integration fast assumes 125ms of exponential averaging while the integration slow assumes 1s of exponential averaging. The program approximates these constants trying to measure the computer speed and varying the number of averages calculated. The rest of the paragraph deals with other applications of the Multi-meter. 8.3.1 THE MINIMIZED STATE It is possible to operate the Multi-meter in what we call a 'minimized' state. Pressing the relative button the control panel collapses and, in its place, remains a stay-on-thetop display as in Fig.8.2. Figure 8.2 This operating mode is very useful; for example suppose you want to measure the total harmonic distortion of a sinusoidal signal while also displaying its frequency content. To do this lets start the FFT and Multi-meter control panels together; then press the Go button in FFT, this will start both measurements (see also 8.6 about this); inside the Multi-meter select the THD parameter and then press the minimized button. You should obtain a measurement situation like the one in Fig.8.3. In this figure we were directly acquiring the output of CLIO while generating a 1kHz sinusoid at 0dBu. Figure 8.3 8.3.2 CAPTURING THE GLOBAL REFERENCE LEVEL Now let's see how to capture a level to be the reference for other measurements. Once this is done all subsequent measurements from within the instruments can be referenced to this by choosing dBREL as the unit of measurement. As an example, let us go back to the procedure described in 3.5.1 which aims at validating a calibration. Chapter 8 - Multi-Meter 87
