what i do GB is after its been flushed ,take a reading AFTER you have moved the lever back into the position for when you produce water. then you can make the desicion if you need to change your resin

i do same as Panorama, if R. O. off for a few days, just flush for 15-20mins, then link up like normal and check TDS is 000 before putting flow into tank, simples   ;D
