DC-190 Ultra Count Installation Manual
1.1 Unpacking and Inspection
Immediately after unpacking, visually inspect the DC-190 Ultra Count to ensure all components are included and
undamaged. If any items were damaged in shipment, notify Rice Lake Weighing Systems and the shipper
immediately.
Ensure all accessories are removed from the cartons, then replace all packing materials in the cartons and store in
a safe place. Use the original cartons whenever shipment of the scale is required.
1.2 Repacking
If the DC-190 counting scale must be returned for modification, calibration, or repair, it must be properly packed
with sufficient cushioning materials and the load cell must be locked to prevent damage to the load cell (see
Section 2.1 on page 6).
Whenever possible, use the original carton when shipping the DC-190. Damage caused by improper packaging is
not be covered by warranty.
1.3 DC-190 Scale Capacities and Resolutions
Counting scales specify two types of resolution:
•Weight (or external) resolution
• Counting (or internal) resolution
Weight resolution is displayed in increments of the full scale capacity which is divided into weight increments.
For example, a 5-lb scale divided into 10,000 display divisions would display weight with 0.0005 lb divisions
(10,000 divisions x 0.0005 lb = 5.0 lb).
Counting resolution is based on the internal resolution of the scale. The weight and counting resolutions for the
DC-190 single- and dual-platform capacities are listed below.
Tables 1-1 through 1-3 list the scale capacities and resolutions for all models of the DC-190 counting scales.
