Track Mode – Changing the Channel 1 and 2 Voltages at the Same Time
The series 2200 multi-‐channel power supplies offer a track mode feature that allows channel 1 and 2
voltages to maintain a desired ratio whenever channel 1 or channel 2 voltages are modified. The
following example demonstrates the steps to enable track mode operation.
Front Panel Operation
STEP 1 Configure CH1 and CH2 voltages to the desired ratio
1.
Press CH1.
2.
Press V-‐Set.
3.
Use the arrow keys, numeric keypad, or the navigation wheel to enter a voltage output (e.g.
10V).
4.
Press Enter to set the voltage of the combined channel.
5.
Press I-‐Set.
6.
Use the arrow keys, numeric keypad, or the navigation wheel to enter a current limit (e.g. 1.5A).
7.
Press Enter to set the current of the combined channel.
8.
Press CH2.
9.
Press V-‐Set.
10.
Use the arrow keys, numeric keypad, or the navigation wheel to enter a voltage output based on
a ratio for the desired change between the channels. Set channel 1 and 2 voltages to the same
value so that both channel voltages change by the same amount (e.g. set channel 2 to 10V). To
have channel 2 change by ½ of the voltage change of channel 1, set the channel 2 voltage to ½
the voltage of channel 1 (e.g. 5V).
11.
Press Enter to set the voltage of the channel 2.
12.
Press I-‐Set.
13.
Use the arrow keys, numeric keypad, or the navigation wheel to enter a current limit (e.g. 1.5A).
14.
Press Enter to set the current of channel 2.
