1.1 Remove the aluminum faceplate of the DP2000 by removing the single
allen-head cap screw located at the bottom front of the faceplate. After the
screw has been removed, carefully lift the front of the faceplate and slide it
towards you about an inch. After the faceplate has been removed, it can
temporarily be rested in the lid of the open case, to allow access to the
components inside. This plate will still be connected to the interior circuit
boards, so care should be taken to maintain all existing connections.

2.1 The microprocessor board is located in the front left side of the unit.
This board contains three very small buttons that are used for calibration.
Two are next to one another, and they are marked “75.3%” and “11.3%”,

The approximate locations of each button are shown on this diagram:

in place by the nut on the black plastic gland.
