3. Set the PS280 or PS283 to series tracking mode by pressing the
left TRACKING button. Make sure that the right TRACKING
button is released (out).
4. Set the master AMPS/VOLTS switch to the voltage metering
position. Set the slave AMPS/VOLTS switch to the current
metering position. This allows you to simultaneously monitor
both current and voltage.
NOTE. In series tracking mode, the output voltage is double the value
displayed on the voltage metering LED display, because both
supplies are producing the same voltage.
5. Set the slave CURRENT knob fully clockwise.
6. Set the current limit using the master CURRENT knob. (Refer to
Setting the Current Limit on page 10.)
