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:

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:
