& limit access to the scale for increased security. Communication is another powerful feature of the LP-II. It comes with an RS-232 port, which can tie a scale to a personal computer (P.C.) for exporting or importing program data. Because PLU and all other data files are kept locally in each scale’s RAM memory, the scale’s speed is the same in a network...
2 Unpacking and Assembly Assembly of Display Column You must follow the instructions in this section in order to assemble the Display Assembly properly. To begin the installation, make sure that the scale is unplugged from any electrical source. Your scale body has a display column bracket in the rear that the display column slides into.
3 Proper Operation 3 Proper Operation Environmental Considerations & Safety 1) Please avoid the following hostile conditions: Temperatures below or exceeding: Ungrounded electrical outlet -10º C ~ 40º C (14º F ~ 104º F) Excessive vibration Unstable or flimsy surface Wind or fans functioning in direct Shared electrical outlet contact with weighing platform.
3 Proper Operation Leveling and Location 1) Location: This scale must be placed on a flat and stable surface. Please keep the scale away from the direct path of oscillating fans, ventilation systems, or strong drafts as these air disturbances can be picked-up by the scale’s very sensitive weighing platform and may cause incorrect weight readings.
If you have any problems or questions regarding this matter, make sure to contact your authorized dealer or the CAS USA Service Department. Note: Be sure to check the LP-2’s serial number plate on the back of the scale for power specifications.
