4-3. Equipment required for Calibration
We recommend as below measuring instruments in other to calibrate the power supply.
4-4. Technic of Calibratio
As below is for calibration technics.
Instruments Connection Drawing.
▌
Connect as Figure. 4-1.
▌
When calibrates voltage, turn off the electronic load or remove the connection from output bus bar.
▌
It is fine to use the general load resistor instead of electronic load.
