If you think you have a problem with your power supply, it is a good idea to check the<br />

actual voltage on the <strong>Raspberry</strong> Pi circuit board. Two test points labelled TP1 and TP2<br />

are provided on the circuit board to facilitate voltage measurements.<br />

Use a multimeter which is set to the range 20 volts DC (or 20v =). You should see a<br />

voltage between 4.75 and 5.25 volts. Anything outside this range indicates that you have<br />

a problem with your power supply or your power cable, or the input polyfuse F3.<br />

Anything inside, but close to the limits, of this range may indicate a problem.
