4.2.5.3 Trapezoidal wave
If the required four time parameters are set greater than 0, the test mode is continuous output In normal mode,
the load output is trapezoidal wave. The frequency characteristics of its description with the triangular wave.
4.2.6 Trigger control
When dynamic test mode is set to pulse mode or trigger mode, trigger control is activated. Trigger in three
ways:
a、 Key trigger
Press Shift + Trigger button in sequence, the trigger
b、 External hardware input trigger
When the load terminal TRIG_IN terminal level is continuously low 5mS or more, a trigger.
c、 PC control software trigger
4.2.7 LIST function
The load can perform sequential operation (LIST function), up to 8 groups of data can be edited, each
group can be edited 200 steps, each step can edit the execution time, the user can define different minimum
time unit in each data, the minimum time unit is 0.02 mS, the minimum time unit setting range is 0.02 ~
1310.7mS, each single-step executable time range is related to the setting of the minimum time unit. If the
minimum time unit is set to 0.02mS, each step can be executed Of the time range is 0.02 to 1310.7 mS, and if
the minimum time unit is set to 2 mS, the time range for each single-step execution is 2 to 131,070 mS.
4.2.7.1. Edit list
1) Press Shift + 0 to enter the menu setting, press ▲ or ▼ key until the load prompts "MENU LIST", press
Enter key to enter, press ▲ or ▼ key until the load prompts "EDIT LIST", press Enter key to enter, press ▲ Or ▼
key to select the serial number to be set and press Enter key to enter LIST edit menu.
2) At this time, the load prompt "MINIMUM TM = xxxxxx mS", which is prompted to enter the minimum time
unit to be set. This value affects the fineness and operational length of arbitrary waveforms. Please choose your
own parameters carefully. After entering the data and pressing Enter, the load prompts the following three output
modes. The user can select with ▲ or ▼ and confirm with Enter.
“LIST CONTINOUS” Expressed as a continuous output.
“LIST END HOLD” Indicates that after all points have been output, the last value remains
unchanged.
“LIST END RESET” After all points have been output, the load is reset to no load.
3) Press Enter key to confirm. The load prompt "STEP LENG = xxx" indicates the total step length to be edited.
The total step must be an integer from 1 to 200. Press number key to confirm.
4) Press the number key to confirm, the load will display "STEP 1 CURR = xxxxxA", prompting the user to enter
the current needed for the first step, press number keys to edit and press Enter key to confirm, then the load will
display "STEP 1 TM = xxxxx mS ", prompting the user to enter the duration of the first step constant current, press
number keys to edit and press Enter key to confirm.
5) Press the Enter key to confirm, if you have edited all the set total step, then display "EDIT LIST", that return
to LIST function main menu. If you have not yet edited the entire set step, return 4) "STEP n CURR = xxxxxA" is
displayed, indicating that you are editing step n data.
6) Since LIST function and automatic test function share a piece of storage space, it is necessary to pay
attention when editing the serial number selected by LIST function. If this serial number was originally used for
automatic test function, after editing LIST function, the same serial number of automatic The test list will be deleted
and can not be recovered.
