RIGOL DP811 Value of current sensing resistor position R52 On circuit (Burned)

[cidak]

Hi everyone.

Big thanks in advance to the people who can help solve my repair problem on RIGOL DP811 (SINGLE OUTPUT 20v/10a 40v/5a).

I stupidly turned off the power supply    while a charging battery was connected to the output.

This incorrect operation caused an SMD current detector shunt resistor to burn out.

I can no longer read the value    because it has burned out...

Can anyone check its value on their power supply, or indicate and/or provide me with the electronic diagram with part list of components of the DP811.

The position on the printout is R52.

I found some photos of a teradown of DP832, (the value is 0.020 Ohm) But the value used by Rigol on DP811 is different.

I can't read the value because the current detector resistor has burnt out. Who can kindly help?

Spending $1000 on a new power supply  for a stupid $2 resistor is crazy.
Help!!!
Thank you

IDK, if 832 model being 3 A rated has 0.02 R shunt then 5-10 A rated 811 model may have 0.01 R or 0.005 R shunt. You may try use one of these values and see how it goes.
