Power Supply
▌Power supply can be used for source for calibration.
▌When you do current calibration, power supply's + terminal should be connected
to load's + terminal and load's - terminal should be connected to current monitoring
shunt's one lead line. Other side lead line should be connected to power supply's
- terminal.
Current-Monitoring Resistor(shunt)
▌Use current monitoring resistor. Normal current measuring instrument is not suitable for
high current capacity.
▌Select less than TCR 10ppm
▌Use 0.01% high precise standard resistor
DVM(Digital Volt Meter)
▌Used for voltage calibration and measuring current monitoring sensing voltage.
▌Resolution: 0.1 mV , Accuracy: more than 0.01%
Programming
This product supports calibration based on PC interface.
Calibration using communication doesn't cause measurement errors and
you can get accurate calibration data.
Below is the PC communication connection diagram.
