3030D as well as the Xantrex LXD30-2/5) are dual tracking supplies. These supplies
may be set to track each other. This tracking feature is not used in any laboratory, and
so these supplies should always be set to their independent mode. Both Instek models
have two pushbuttons on the middle of their front panel—for independent operation,
both pushbuttons should be in the out position.
For the Xantrex, the
independent/tracking toggle switch should be set to independent.
The power supplies mentioned above also have a single fixed 5 V supply built
into them as well. The output from this supply is found on the far right of the front panel.
When setting up a circuit, make sure that your power supply is set to the proper
voltage before you connect it to your circuit. You don’t know what a supply is set to
when you take it off of the shelf: the person that used it before you could have had it set
to +60 V. If you hook it up to your circuit that is supposed to have a power supply of
+10 V, what will happen? One last word of caution: don’t trust the meters on the
supplies themselves—always use a multimeter to confirm the output voltage.
Frequently the built-in meters on the supplies are inaccurate.
