power supply will be triggered once.
Software: if the trigger command is received by the power supply from the
communication interface in the valid software trigger mode, the power
supply will be triggered once.
Bus: if the bus trigger command is received by the power supply in the valid
bus trigger mode, the power supply will be triggered once.
External: if one trigger signal is connected to the pin 9 of the Analog
Interface terminal on the rear panel, the power supply will be triggered
once.
3.16 External Simulation Test Function
The rear panel of the power supply is equipped with a DB-9 simulation interface
used for controlling the on-load voltage. The adjustable voltage can be
connected to the simulation interface to simulate the output from 0 to the full
range, thus adjusting the output voltage.
Press [Shift]+[Setup] (Menu) to enter the [System Setup] interface. Select
Ext-Ctrl and set it in the ON state. Exit the menu. Then will appear on the
LCD screen. Press [M1] on the front panel to exit the external simulation
function.
DB-9 terminal is defined as follows.
External reference input.
System FAIL state signal

3.17 Remote Measurement Function
If the tested instrument consumes large current, a large voltage drop will be
detected in connection line between tested instrument and power supply
terminal. To ensure measurement accuracy, a remote sense measurement
terminal is provided at power supply rear panel to compensate voltage drop lost
in wire.
