should be display on the front panel LCD.
Press “ 3” to select RB CV1. Then press enter.
CV1 LO= CNT: Input measured voltage from Volt.DMM, then press ENTER
CV1 HI = CNT: Input measured voltage from Volt.DMM then press ENTER key. A “SUCCESS” message
should be display on the front panel LCD.
Press “ 3” to select RB CV2. Then press enter.
CV2 LO= CNT: Input measured voltage from Volt.DMM, then press ENTER
CV2 HI = CNT: Input measured voltage from Volt.DMM then press ENTER key. A “SUCCESS” message
should be display on the front panel LCD.
CC LOW RANGE READBACK LEVEL CALIBRATION
CC readback low range calibration requires a power supply that covers full range of high range input current of load.
Estimate the power consumption of the electronic load, and adjust the voltage input to a safe limit for the load.
Use “ 4” and “3” until you see RB CRO parameter. Press enter:
CC0 LO= CNT: Input measured voltage from Curr.DMM, then press ENTER.
CC0 HI = CNT: Input measured voltage from Curr.DMM then press ENTER key. A “SUCCESS” message
should be display on the front panel LCD.
Press “ 3” to select RB CC1. Then press enter.
CC1 LO= CNT: Input measured voltage from Curr.DMM, then press ENTER
CC1 HI = CNT: Input measured voltage from Curr.DMM then press ENTER key. A “SUCCESS” message
should be display on the front panel LCD.
Press “ 3” to select RB CC2. Then press enter.
CC2 LO= CNT: Input measured voltage from Curr.DMM, then press ENTER
CC2 HI = CNT: Input measured voltage from Curr.DMM then press ENTER key. A “SUCCESS” message
should be display on the front panel LCD.
This completes the calibration for all the input parameters for the electronic load.
Press “3” & “ENTER” key simultaneously to save all new calibration parameters into the load’s memory.
RE-INSTALLING CALIBRATION DATA
In case, the calibration data becomes corrupted by abnormal conditions, the Electronic Load has a built in capability for
re-installing the last calibration data without having to recalibrate the load.
1. First you need to read the slope and offset values from the electronic load when you receive the unit, or you can
call
$0(7(.3URJUDPPDEOH3RZHU,QFto get the calbration information for the elctronic load (need serial
number)
Get calibration data procedure:
Get slope value:
Run command: “SYST: SLOPE? ” to get calibration slope values where “mode” is from 0 to 39. So
there should be 40 values for slope data.
Get offset value:
5-8
