INSTALLATION
Before beginning installation of your CN20 weight indicator, make certain that the instrument has
been received in good condition. Carefully remove the instrument from the shipping carton and
inspect it for any evidence of damage that may have taken place during shipment. Should your CN20
come already installed on a scale, the following information describing the installation of the
instrument does not apply to you.
Begin the installation by deciding where the instrument is to be mounted. The CN20 may come
mounted on a column or you may choose to mount it on a desktop or wall. Refer to Figure no. 1 for
illustrations of these various mounting arrangements. Note: If you use the mounting bracket on the
scale column you may select any of these variations. Two (2) holes are located in the mounting
bracket for attachment to the wall or column top. This bracket may be removed or left in place for
desktop use. To remove the bracket, pry outward on the bracket at each of the pivot points while
pressing the tilt buttons and pulling downward on the bracket.
