EX Series Operating Manual
Electronic Load.
▌This instrument is for power supply's current calibration. Electronic load is kind of variable
resistor.
▌This instrument must have ON/OFF function and itself's short function for testing.
▌When current calibration, connect the power supply (+) output terminal and electronic load

and connect the power supply (-) output terminal and shunt lead for current monitoring
and then connect shunt's the other lead to electronic load (-) terminal
▌It must be able to communicate to PC.
Current-Monitoring Resistor(shunt)
▌Normally, current measuring instruments is not suitable high current capacty's measuring,
so generally, use current monitoring resistor.

▌Select shunt that TCR is below 10ppm.
▌Select shunt that precision is around 0.01%.
DVM(Digital Volt Meter)
▌It is used for voltage calibration and current monitoring sensing
▌It must be, the resolution : 0.1 mV , Accuracy : below 0.01%.
▌It must be able to communicate to PC.
▌It must be able to communicate to PC.
Programming
Our power supply is based on PC interface calibration.
If you use the communication calibration, it is not caused measuring error and also you can
measure the accurate calibration data.
Below is PC communicaton connection drawing.
