Display Measurement Data
Measurements are always active and can be displayed as follows:
1. For voltage, the left display always displays the measured output voltage unless the knob
is turned. As the knob is turned, the programmed voltage will be displayed instead. After
releasing the knob for about 3 seconds, the display reverts back to the measured
voltage.
2. All other measurements can be displayed by using the SELECT button to toggle through
the available measurements. The LED’s above the LED segment display indicates the
current selection. The knob only affects the current limit set.
3. Moving the right shuttle knob will interrupt the selected measurement and put the display
back in Current Limit adjust mode.
4.2.4
Control the Output
The Output can be disabled or enabled using the ON/OFF button as follows:
1. Pressing the OUTPUT button when the output LED is on will turn off the DC supply output.
The programmed voltage setting will remain at the last program value.
2. Pressing the OUTPUT button again will engage the output and the output will revert to the
last programmed value.
4.2.5
Measure Peak Inrush Current
The peak current measurement function of the XDS Series uses a sample and hold circuit to
track the highest peak current found until reset. The peak current sample and hold circuit is reset
any time the user toggles away from the peak current display mode to a different measurement
using the SELECT button.
The peak inrush current for a unit under test can be measured using this function as follows:
1. Program the output to zero volts and turn off the output using the ON/OFF button.
2. Use the SELECT button to display the present peak current value.
3. Use the SELECT button again to toggle to any other measurement readout. This will
effectively reset the peak current sample and hold circuit to zero amps.
4. Use the left shuttle knob to set the voltage to the nominal supply voltage of the unit under
test.
5. Use the OUTPUT ON/OFF button to apply the programmed voltage to the unit under test.
6. Use the SELECT button to display the measured peak current value.
