1. The power switch turns on the instrument when pressed. When you press
it again, the instrument is turned off.
2. The switches labeled TRACKING determine the test mode of the instru-
ment. The PS280 or PS283 features two tracking modes: series and
parallel. If both push-button switches are disengaged (out), the two vari-
able power supplies operate independently. If the left switch is pushed in,
the instrument operates in series mode. If both switches are pushed in, the
instrument operates in parallel mode.
In series mode, the master power supply controls the voltage for both
power supplies, which can then range from 0 to 60 V.
In parallel mode, the master power supply controls both the voltage and
the current for both power supplies. The current can then range from 0 to
4A(0to2AforthePS283).
