Hi, I have two DM502As that supposedly have option 2 installed as per the sticker on top.
The issue is that the circuits meant to be omitted in option 2 are not omitted, it seems. U1004, CR1101, R1103, and other surrounding components that should have been omitted are there!
So I am wondering, can I buy a P6601 and use it with my DM502A and not worry about my DM502As not supporting the temperature measure option?
Thanks
