I would like to calibrate my tank monitors,but Mine control panel does not have any screws to adjust,any help would be great.the plate has KIB on the front.
Unfortunately, as a previous post indicated, there is little or no adjustment available on any of these systems. Our experience through several different units over the years is that they are seldom very accurate. That said, most offer at least some guidance once you become familiar with how the readings relate to your particular unit and its characteristics.
