Set EXTC (External Interface)
The “EXTC” tab includes: (Int, ExtI, ExtV), ExtSwitch, I_M_ON, V_M_ON four
tabs. It mainly supplies the way user controls the external terminals on the rear
panel, current and voltage monitor, external control ON/OFF.
Int
The load will return the mode before enter “EXTC” tab after select the “Int”
tab.
ExtI
After selecting “ExtI” tab, the load will display the ExtI interface. It includes:
Type, RangeI, RangeV options. The sink current of the load can be
controlled by the “EXT” terminals on the rear panel of the load. The input
voltage is not suggested to be greater than 10V, otherwise it may destroy
the load. Users can simulate input current of the load which ranges from
zero to full current range.
Operating Steps
1. Connect device
Power on the instrument and connect the DUT and the channel input
terminals of the electronic load, as shown in Figure 2-2.
Warning
The input voltage range of the “EXT” terminals is 0-10 V. To avoid
damage to the instrument, please pay attention to the polarity of the
device terminals .
2. Set running parameters
Press the Shift + CP key on the front panel to enter system utility
function interface. Select “Config” option and Switch to page 2, then
