CONTINUOUS MODE
In continuous mode, the eLOAD input switches between 2 user defined levels; main and transient. The duty cycle and
frequency is user defined.
Typical application: Testing the Load Regulation (Effect) of a power Supply, defined as the voltage change in dc output
due to a change in load current from minimal resistance (closed circuit) to maximum resistance (open circuit). The PLW
can be programmed to switch between any two current levels.
LCL Operation:
1. Using the mode hot keys, select operating mode (CC, CV, CR, CP)
2. Set the MAIN level by holding down the encoder and rotate to change the value or enter numerically.
3. Set the Transient level by pressing the “PEAK” hot key and edit the value using the encoder or enter manually.
4. Select Continuous transient operation by pressing the “CONT” hot key.
5. Set the duty cycle and frequency by pressing the “DUTY” and “FREQ” hot keys and tapping the encoder to edit
each. The duty cycle can be set from 2% to 98% and the frequency from 0.1Hz to 10 KHz. Rotate the encoder
clockwise or counterclockwise to change values or enter manually.
6. Set the Rising and Falling Slew Time by pressing “SLEW,” rotate the encoder to select option, tap the encoder
to edit slew time value and press “ENTER” to confirm value entry.
7. To begin the continuous transient operation, press the “PULSE” hot key (pulse hot key will blink) and then press
the “INPUT” hot key to activate the Continuous transient operation.
