Calibration Voltage Failing

[scooterdoo1]

Hello,

I received this kit as a way to learn about electronics and to learn more about various skill sets. I received my board and followed your calibration guide with the help of this video . I set my R100 to 50 Ohms and then when I turn the board on I only see .9 volts. I am using an Auto ranging multimeter but I locked it into V and it shows .9V . I ideally wouldn't like to purchase another one so would you know how to diagnose or test if my board is failing to step up the voltage? Thank you for your time!
