Generally speaking, you don't want the RH to below 40% for most equipment. Besides drying the lubrication, there is also a chance of static build-up which can damage your equipment. The setting most recommended for equipment (including computer rooms) is a RH level of between 45%-55%.
Ok guys...I think something is not rite with my dry cabinet
I tried adjusting more to the H, the RH% drops to 30%...thot it should go up to 40 n above (it was at 40 before I did any re-adjustment)
Does the RH% meter need to take some time before reflecting the actual readings?
I did not add or took anything out from it when I was doing the re-adjustment. Only thing that happen was tat the door was left open for about 15mins.
