4.2.6 MEASUREMENTS Screens
The MX Series uses a DSP based data acquisition system to provide extensive information
regarding the output of the source. This data acquisition system digitizes the voltage and current
waveforms and calculates several parameters from this digitized data. The results of these
calculations are displayed in a series of measurement data screens. A total of three
measurement screens are used to display all this information.
Figure 4-6: MEASUREMENT Screen
The Measurement screens available on the MX15 Series are not menus in that no changes can
be made anywhere. Instead, these screens provide load parameter readouts. The measurement
screens can be reached by successively pressing the Meas key, which will toggle to all available
screens. Note that for -1 Series models, only the first two screens are available. For the
–1Pi
series, all three measurement screens are available.
The following parameters are available in the measurement screens:
ENTRY DESCRIPTION
MEASUREMENTS 1
VOLTAGE This value is the true rms output voltage measured at the voltage
sense lines.
CURRENT This value is the true rms output current drawn by the load.
FREQ The output frequency is measured at the sense lines.
TRUE POWER This value is the real power.
MEASUREMENTS 2
VA POWER This value is the apparent power.
POWER FACTOR This readout shows the power factor of the load.
PEAK CURRENT This value is the instantaneous peak current. See also PEAK CURR
in MEASUREMENTS 3 screen.
CREST FACTOR This readout displays the ratio between peak current and rms
current.
MEASUREMENTS 3 (iX Models only)
CURR THD This readout displays the total current distortion for the selected
