Lab 1: Use 5V instead of 10V
The power supply's 3rd channel can only supply 5V. Since you will most conveniently supply power to the IC (pin 14) from that channel, you cannot use 10V. So let's just use 5V instead.
P.S: Background explanation: 1) You need a seperate channel for pin 14 from the one providing the drain voltage, since you want to measure the current going to the drain accurately. 2) Pin 14 is also used for protecting any input against voltages higher than Vdd, so it needs to be the highest voltage on the chip too. So using 10V on the drain and only 5V on pin 14 would not work either...
