CV READBACK LEVEL CALIBRATION
CV rea dba ck ma in level ca libra tion requires a power supply tha t co vers full ra nge of input volta ge of loa d and is ca pa ble
of opera ting in CV a nd CC mode. Estimate the power consumption of loa d, because power supply will go to CC mode
while ca libra ting the loa d. Adjust the CC current level to sa fe limit of loa d.
Use “

” and “

” until you see RB CV0 parameter. Then press enter:
CV0
LO= CNT: Input mea sured volta ge from Volt.DMM, then press ENTER.
CV0 HI = CNT:
Input measured voltage from Volt.DMM then press ENTER key. A “SUCCESS”
should be displa y on the front pa nel LCD.
Press “
 ” to select RB CV1. Then press enter.
CV1
LO= CNT: Input mea sured volta ge from Volt.DMM, then press ENTER
CV1 HI = CNT:
Input measured voltage from Volt.DMM then press ENTER key. A “SUCCESS” message
should be displa y on the front pa nel LCD.
Press “

” to select RB CV2. Then press enter.
CV2
LO= CNT: Input mea sured volta ge from Volt.DMM, then press ENTER
CV2 HI = CNT:
Input measured voltage from Volt.DMM then press ENTER key. A “SUCCESS” message
should be displa y on the front pa nel LCD.
CC LOW RANGE READBACK LEVEL CALIBRATION
CC rea dba ck low ra nge ca libra tion requires a power supply that covers full ra nge of high ra nge input current of loa d.
Estima te the power consumption of the electronic loa d, a nd a djust the volta ge input to a sa fe limit for the loa d.
Use “
 ” and “  ” until you see RB CRO parameter. Press enter:
CC0
LO= CNT: Input mea sured volta ge from Curr.DMM, then press ENTER.
CC0 HI = CNT:
Input measured voltage from Curr.DMM then press ENTER key. A “SUCCESS” message
should be displa y on the front pa nel LCD.
Press “

” to select RB CC1. Then press enter.
CC1
LO= CNT: Input mea sured volta ge from Curr.DMM, then press ENTER
CC1 HI = CNT:
Input measured voltage from Curr.DMM then press ENTER key. A “SUCCESS” message
should be displa y on the front pa nel LCD.
Press “
 ” to select RB CC2. Then press enter.
CC2
LO= CNT: Input mea sured volta ge from Curr.DMM, then press ENTER
CC2 HI = CNT:
Input measured voltage from Curr.DMM then press ENTER key. A “SUCCESS” message
should be displa y on the front pa nel LCD.
This completes the calibration for all the input parameters for the electronic load.
Press “3” and “ENTER” key simultaneously to save all new calibration parameters into the load’s memory.
