TRACKING 2 (percentage change)
The outputs of target channels change at the same percentage along with the changes in the reference
channel. When TRACKING 2 is enabled, the voltage and current set on each channel at that moment
become the reference values (100 %), and changes are made from there.
If the output of a target channel reaches its maximum output setting or 0 V (or 0 A) when the reference
channel percentage is changed, the display no longer changes but the amount of change in the target
channel is recorded. When the output is returned to its original value (100 %), the outputs of the target
channels also return to their original values.
Example: Here we will use TRACKING 2 on CH1 and CH2 of a PMX32-2QU.
When you turn the rotary knob during tracking operation, the outputs change at the same percentage
as the preset output percentage (b/a).
b/a = d/c
This proportional expression is satisfied.

When the maximum voltage is
reached, the display stops changing.
But, the amount of change is
recorded.
