Refer to page 9 of the application note titled National Semiconductor: LM134/LM234/LM334 3-Terminal Adjustable Current Source, listed in the Resources section. Use the circuit schematic titled "Basic 2-Terminal Current Source" as the reference for making your basic current source.
Order the LM134H metal can version (which is a three-lead version of the LM134 component encapsulated in a metal package shaped like a small can) Check to see if the LM134H you received is packaged in a metal can package with three leads. Don't use the semiconductor if it does not have three leads because it is either a different version of the part or is the wrong part.
Examine the bottom view of the LM134H. Note that the lead that is the first lead clockwise from the extruding tab is called the R lead and is used for the resistor connection. Note that the second lead clockwise from the tab is called the V+ lead and is used for the positive voltage supply lead connection. Note that the third lead clockwise from the tab, is called the V- and is used for the negative voltage supply connection.
Insert the three leads of the LM134 into your electronic breadboard. Connect the positive lead of your power supply to the V+ lead of the LM134H. Connect the negative lead of your power supply to the V- lead of the LM134H. Attach the positive lead of your ammeter to the R lead of the LM134H then connect the ammeter's negative lead to the left lead of the 1000 ohm resistor. Attach the right lead of the 1000 ohm resistor to the V- lead of the LM134H.
Turn on your power supply. Raise its voltage (but don't exceed 40 Volts, the absolute maximum voltage rating for the LM134 series). Observe that the current reading on the ammeter's display increases as you raise the supply voltage. Turn off your power supply and replace the 1000 ohm resistor with a 2000 ohm resistor. Turn on your power supply and vary its voltage. Observe that the current readings for the voltage levels are different than the values you obtained with the 1000 ohm resistor.
