In this section, I will examine the workflow of a set of tools that will streamline your search for the driver you need. These tools can be useful when you are facing great deal of time-consuming, manual work or do not have the necessary off-the-shelf tools to deal with such work.
The most important thing we always want to do when developing and testing energy efficient systems that require AC/DC input is to ensure that our EKFVX is calibrated with the exact characteristics of the energy efficient device we are testing in our lab. If our calibration is correct, the output of our EKFV is very close to what we are testing in our lab. Every voltage source in our lab is calibrated to within 0.1 volt, so our calibration procedure with the EKFV is easy.
An important step in a diagnostic test for a power supply is to check for the correct polarity of the input and output. A good polarity is black and white, sometimes with a little band of gray. A good polarity should go from negative to positive, positive to negative, and then positive to positive again. If your polarity test shows black or white on the wrong side of the picture, that can be a sign that the device is not working properly.
The next step is to determine if the output levels are in the proper range. A good way to check this is to use a multimeter. You can find one in almost any good retailer's electronics department. The output of the EKFV is AC Voltage, so use a multimeter with AC voltage measurement capability. This can be found in the multimeters manual or by including an AC voltage feature in the multimeter. In the multimeter menu, you should be able to measure output voltage, input voltage, and other voltage parameters from the EKFV. d2c66b5586
