1.1Unpacking 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.

1.2Repacking

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.

1.3DC-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 singleand 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.

Model			Capacity (lb)			Weighing Resolution (lb)			Internal Resolution (lb)				Platform Dimensions

2.0Installation

This section describes the procedure for the installation and setup of the DC-190 counting scale.

2.1Locking and Unlocking

Do not turn scale upside down. Always Caution work with scale on its side! Damage to

the load cell can occur if the scale is turned upside down.

The DC-190 counting scale is delivered in a locked position to prevent damage to the load cells during shipment.

To prevent damage to the load cells, Caution scale must be locked prior to shipment.

The scale uses either one setscrew for the single-platform scale or two setscrews for the dual-platform scale. The setscrews are located on the bottom of the base and must be removed before the scale is put into service. Use the following procedure to unlock your DC-190 counting scale.

1.Turn scale on side. Loosen locknut 1/4 turn (see Figure 2-1).
