0.02mS to1310.7mS; if the minimum time is set at 2mS
，
then the duration of each step ranges from 2mS to
131070mS.
4.2.7.1. List Operation
1) Press the Shift+0 keys to enter the menu operation, and then use the
▲
and
▼
keys to get to
MENU LIST , followed by keying Enter to confirm. Then press the
▲
and
▼
keys to reach EDIT LIST ,
followed by pressing Enter to confirm. Then press the
▲
and
▼
keys to select the sequential code that
needs to be set, followed by pressing Enter to confirm.
2) When the display shows MINIMUM TM= xxxxxx mS , it indicates the minimum required time
setting. Since this value affects the fine tuning and operable length of all thewaveforms, please select the
suitable parameters carefully. Then press Enter to confirm. The electronic load will offerthe following three
output modes: LIST CONTINOUS, LIST END HOLD, and LIST END RESET . Press the
▲
and
▼
keys to
select the output mode desired, and press Enter .
LIST CONTINOUS means continuous output mode.
LIST END HOLD means the electronic load will retain the last value set in the last step when all
the steps in one set of data have been successfully executed.
LIST END RESET means the electronic load will reset itself to load off mode when all the steps
set in one set of data have been successfully completed.
3)After pressing Enter to confirm, the VFD panel displays STEP LENG= xxx , indicating the
required step length that needs to be set. Press the numeric keys to input the step length desired, followed
by pressing Enter to confirm. Please note that the step length should be a round number between
1~200.
4)When the VFD display shows STEP 1 CURR=xxxxxA , it indicates the required current that needs
to be set in the first step. Use the numeric keys to input the current desired in the first step, and press
Enter to confirm. When the display shows STEP 1 TM=xxxxx mS , it indicates the current duration of the
first step. Press the numeric keys to input the current duration desiredin the first step, followed by pressing
Enter to confirm.
5)After all the setting steps have been entered, the VFD panel will display EDIT LIST ,which means
exiting back to the beginning at list function. If all the setting steps have not been edited, the display will
show S TEP n CURR=xxxxxA . This means that the value of the N step needs to be changed. Make the
required changes following the operating instructions in the previous step 4).
6)Since list function shares the same storage space as the automatic testing function; make sure that
the sequential code selected in the list function is the same as that in automatic testing function. If the
sequential code defined for the automatic testing function prior tonow is also the same entered for list
function, this sequential code of the automatic testing function of will be deleted and cannot be restored.
4.2.7.2 Executing List Function
Press the Shift+0 keys to enter menu configuration, and then press the
▲
and
▼
keys to
arrive at MENU LIS , and press Enter .. Now press the
▲
and
▼
keys to get to LOAD LIST , and press the
Enter .. Then press the
▲
and
▼
keys to set the sequential code of the list function you want to execute,
andpress Enter .
Since the list function shares the same storage space as theautomatic testing function, the
sequential code set for the automatic testing function will be automatically shielded from the sequential
codes chosen for the list function.
4.2.8 Automatic Testing Function
The DC electronic load provides an automatic testing function in which 8 data parameters can be set,
maximum, and 50 steps that can be changed within each set of data. Each step can be selected from
among the following six working modes: load off mode, constant current mode, constant voltage mode,
