Figure 13: Parallel Tracking Inside the PS280 or PS283
To test a circuit in the parallel tracking mode, follow these steps:
1. Turn the POWER off to the PS280 or PS283.
2. Connect the outputs as shown in Figure 14 on page 24.
3. Set the PS280 or PS283 to parallel tracking mode by pressing
both tracking buttons.
4. Set the master AMPS/VOLTS switch to the voltage metering
position, and set the slave AMPS/VOLTS switch to the current
metering position. This allows you to simultaneously monitor
both current and voltage.
NOTE. In parallel tracking mode, the output current is double the
value displayed on the current metering LED display, because both
supplies are producing the same amount of current.
5. Turn on the POWER to the PS280 or PS283.
6. Set the current limit using the master CURRENT knob. (Refer to
Setting the Current Limit on page 10.)
