1. First, select the load’s mode of operation, which will determine which type of transient operation will be congured.
Press or to select between CC, CV, CW, or CR mode. Verify the selection by the backlight behind its corresponding
button, which will be lit when selected.
2. Enable transient mode from the “Tran” menu. This is accessed via + ”.
3. Select the transient mode “Continuous”, “Pulse”, or “Toggle”. Press .
6.3.1 CC Mode
In Constant Current mode, the congurable parameters are the following:
Mode Continuous, pulse, or toggle
Up The rising edge current slew rate in A/us.
Down The falling edge slew rate in A/us.
Level A, Level B The 2 current levels applied.
In Continuous mode, the following are also set:
Freq The transient cycle frequency.
Duty The duty cycle or percentage of time the load will be at either level (A/B). The percentage de-
nes the ratio of the B level to the cycle. So for 75% and 1 Hz, the B level will be on for 750
ms and the A level 250 ms.
In Pulse Mode, the following is also set:
Width The transient frequency
6.3.2 CV, CW, and CR modes
In Constant Voltage, Power and Resistance modes, the congurable parameters are the following:
Mode Continuous, pulse, or toggle
Level A, Level B The 2 levels.
In Continuous mode, the following are also set:
Freq The transient cycle frequency.
Duty The duty cycle or percentage of time the load will be at either level (A/B). The percentage de-
nes the ratio of the B level to the cycle. So for 75% and 1 Hz, the B level will be on for 750
ms and the A level 250 ms.
In Pulse Mode, the following is also set:
Width The transient frequency
6.4 LIST Operation
List mode allows you to generate a complex current sequence. Moreover, the mode change can be synchronized with an
internal or external signal to accomplish dynamic and precise test. A list le includes following parameters: le name,
step count (range 2-84), step width (0.00005 s - 3600 s), step value and slope. The list le is saved in memory for later
recall. There is storage for up to 7 list programs. In list mode, the load starts the list following a trigger signal. The list
will continue run to completion or until another trigger signal is received.
