2. Assemble the circuit as shown in Fig. 2. Plug the power
cord in a power outlet.
3. Connect M1 to T1 according to Fig. 2 and measure the
voltage.
4. Change the connection of M1 from T1 to T2 and measure
the voltage again.
5. The voltmeter must read 0.375 V or lower in both of steps
3 and 4. This means that the current must be 0.75 mA or
less.
