table below).

For two channels supporting the track function, when the track function of one
channel (the tracked channel) is enabled, the voltage setting value of the other
channel (the tracking channel) will change accordingly when the voltage setting
value of this channel is changed. By default, the track function is disabled and it is
usually used to provide symmetric voltage for the calculation amplifier or other
circuits.
Operation Method (Take DP831A for example):
1. Turn on the power switch to start the instrument.
2. Enable the track function
Select CH3 and press Track to enable the track function. At this point, the track
status label
is displayed in the CH2 area in the user interface.
3. Set the voltage
Press Voltage to set proper voltage. At this point, the voltage of CH2 changes
accordingly. For example, set the voltage of CH3 to -5V and the voltage of CH2
will change to +5V automatically.
4. Disable the track function
Select CH3 and press Track to disable the track function.
Tip
 The track function only tracks the voltage setting value and the actual output
voltage will not be affected.

When the track function is enabled, the voltage of the tracking channel cannot
be set.
