3.14 External On/Off Control
The input switch of IT8600 electronic load can be controlled by the external TTL
level. When the external level is low, the load switch will be in the On position;
otherwise, the load switch will be in the Off position. The input switch of the load
can only be controlled by the external TTL level.
For IT8620 series, including IT8624, IT8625, IT8626, IT8627 and IT8628, the
user must set the “Ext Prog” item into the “On” state in the menu before using
this function.
1. Press [Menu] to enter the menu setting interface.
2. Press the soft key corresponding to [SYSTEM SETUP] to enter the system
setting interface.
3. Press the Down key and select “Ext Prog”. Set the “Ext Prog” item into the
“On” state.
4. Press [Esc] to go back.
3.15 External Analog Quantity Control (Only for IT8615
/IT8615L)
IT8600 electronic load has an analog input terminal. Loading voltage or current
of the electronic load can be controlled by analog quantity terminal on rear
panel. Connect 0-10V adjustable voltage at the Ext-prog terminal to analog
input from 0- full range so as to adjust input voltage and current of load (10V
corresponds to voltage or current of load at full range).
The user must set the “Ext Prog” item into the “On” state in the menu before
using this function.
5. Press [Menu] to enter the menu setting interface.
6. Press the soft key corresponding to [SYSTEM SETUP] to enter the system
setting interface.
7. Press the Down key and select “Ext Prog”. Set the “Ext Prog” item into the
“On” state.
8. Press [Esc] to go back.
3.16 Voltage/Current Monitoring (I/V Monitor)
IT8600 electronic load has an output terminal for voltage and current monitoring.
The user can connect this terminal to the oscilloscope of the BNC terminal to
observe the current and UUT output voltage of the load. This function is
effective when the voltage and current changes are monitored according to the
waveform.
For the voltage/current monitoring output terminal, the 0-10V analog output
signals represent the input voltage/current from 0 to the rating in the
corresponding channel where the terminal is located.
3.17 Parallel Function
IT8600 programmable AC/DC load can be used in parallel connection of
multiple units of the same models to test power supplies of high power. In
parallel application, AC and DC operations can be carried out in the CC/CR/CP
mode.
