CD-1 Indicator
2.2 Selecting the Location
The CD-1 Indicator should be used in an environment which is free from vibration, temperature or humidity extremes.
These factors will affect displayed weight readings. Scale bases used with the CD-1 Indicator should be located on a
stable, level surface and kept away from vibrating sources such as large machinery. Maximum accuracy will be
achieved when the working area is clean and vibration free.
2.3 Cautionary Notes
• The CD-1 Indicator must not be operated in wet or hazardous areas.
• Before connecting the AC adapter, verify that the indicated voltage corresponds to the local mains voltage.
2.4 Connecting the CD-1 Indicator to a Scale Base
The scale base is connected to the round, 4-pin connector located on the right side of the CD-1 Indicator. The mating
connector supplied in the packaging must be attached to the load cell cable. Slide the connector shell over the load cell
cable. Orient as shown in the illustration. Refer to the scale base manufacturer's information to determine the proper
load cell connections. Solder the load cell cable to the connector contacts according to table 2-1 and refer to the the
connector illustration.
NOTE : Any extra load cell connection wires should be isolated and insulated.
