3270 Series Operation Manual 7
1.1.2. Linear C.C. Mode
During Linear C.C. mode, the load current input into 3270 Series High Power Electronic
Load depends on the current setting regardless of the input voltage, e.g., the current setting
remains unchanged. Please refer to Fig.1-7. The load input current signal will follow input
voltage signal, That is useful for step wave-form and square wave-form device.

1.1.3. CR Mode:
At Constant Resistance mode, the 3270 series Electronic Load will sink a current linearly
proportional to the load input voltage in accordance with the programmed resistance setting
(see Fig 1-8).
