Electronic Load
▌Electronic Load should variate Resistor to be used in power supply current calibration.
▌Load should have ON/OFF function, also with short function for the test.
▌While Current Calibration, connect Power supply (+) output terminal with Load (+) termina

and Load (-) output terminal with current monitoring shunt lead with oppsite side of
power supply (-) output terminal.
Current-Monitoring Resistor(Shunt)
▌Use Current Monitoring Resistor, because general current measuring instrument is not
appropriete for high current.

▌Select less than TCR 10ppm.
▌Use high-precision of 0.01% Standard resistor.
DVM(Digital Volt Meter)
▌DVM can be used for voltage calibration & current monitoring.
▌Use performance with Resolution: 0.1 mV , Accuracy: 0.01%.
Programming
This product support PC Interface based Calibration.
Calibrating using GPIB connecting DVM, Ammeter, Load will be very accurate,
and measures calibration data safely.
