1.0 Introduction
The Rice Lake Dual-Range Veterinary Scale (VS-11) provides precise weighing of animals for accurate, reliable and
repeatable weighments. Movement compensation technology eliminates errors caused by spontaneous movement of the
animal and the weight can be displayed in pounds/ounces or in kilograms.

2.0 Setup
The VS-11 comes fully assembled and includes the scale and a 120 V adapter. Immediately after unpacking, visually inspect
the VS-11 to ensure all components are included and undamaged. If parts were damaged in shipment, notify Rice Lake
Weighing Systems and the shipper immediately.
Use the following instructions for scale setup:
1. Place the scale on a sturdy, level surface.
2. Connect the 120 V adapter to the back of the scale.
