CONTINUOUS MODE
In continuous mode, the eLoa d input switches between 2 user defined levels; ma in a nd tra nsient. The duty cycle a nd
frequency a re user defined.
Typica l applica tion: Testing the Loa d Regula tion (Effect) of a power Supply, defined a s the volta ge change in dc output
due to a cha nge in loa d current from minima l resista nce (closed circuit) to ma ximum resista nce (open circu it). The PLW
ca n be progra mmed to switch between a ny two current levels.
LCL Opera tion:
1. Using the mode hot keys, select opera ting mode (CC, CV, CR, CP)
2. Set the MAIN level by holding down the encoder a nd rota te to cha nge the va lue or enter numerica lly.
3. Set the Tra nsient level by pressing the “PEAK” hot key a nd edit the va lue using the encoder or enter ma nually.
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 t he encoder to edit
ea ch. The duty cycle ca n be set from 2% to 98% a nd the frequency from 0.1Hz to 10 KHz. Rota te the encoder
clockwise or counterclockwise to cha nge va lues or enter ma nua lly.
6. Set the Rising a nd Fa lling Slew Time by pressing “SLEW,” rota te the encoder to select option, ta p the encoder
to edit slew time value and press “ENTER” to confirm value entry.
7. To begin the continuous tra nsient opera tion, press the “PULSE” hot key (pulse hot key will blink) a nd then press
the “INPUT” hot key to activa te the Continuous transient operation.
