3.18.2 Current monitoring (I-OUT)
The 0-10V analog quantity output signal of current monitoring output terminal
represents input current to which the terminal belongs from 0 to full range. An
external voltmeter or oscilloscope can be connected to display input current
change.
3.18.3 External analog quantity test
Loading current of the electronic load can be controlled by EXT PRG (positive
and negative) analog quantity terminals on rear board. Connect 0-10V
adjustable voltage at the EXT PRG terminal to analog input from 0- full range so
as to adjust input current of load (10V corresponds to current of load at full
range).
Operation
1.
Press [Shift] + 9(Config) keys to enter menu.
2.
Operate
3.
Select ON and start external analog function.
4.
Press [Esc] exit the menu and the screen displays Rear.
Connecting the terminal as follow.
3.19 Auto Test Function
The IT8300 series electronic load delivers strong auto test functions, which can
analog several tests. A total of 10 groups of test files can be edited, and each
group test file has 10 steps. Therefore, a maximum of 100 steps can be edited
and saved in EEPROM.
The edited test file can be recalled and tested at any time. The test operation is
simple. In addition, all keys can be locked (press [Shift] + [On/Off] (Lock)) to
avoid affecting normal test due to accidental touch of the keyboard.
All test files can be linked to each other (for example, link File1 to File2). Each
group of test file includes parameters below: loading mode (CC/CV/CR/CW,
CC dynamic mode, user can set current rising and falling slope.
value (Value), loading time (Ton), unloading time (Toff), delay time (Tpf), low
and high limit range (Low & High) of judgment values, and test stop conditions.
They are useful for executing a set of tests on a device, then displaying whether
the tests passed or failed. Automatic test operation includes four steps: Edit,
save, recall and run.
