SPECIFICATIONS FOR THESE SCALES
General
The Model 2650KL and 2700KL Patient Scales use highly sophisticated microprocessor
technology. Each precision scale is designed to provide accurate, reliable, and repeatable
weight measurements. In addition, each scale is designed to provide the user with features that
make the weighing process simple, fast, and convenient.
These scales are set up to use motion-sensing weighing technology in order to determine the
actual weight of a moving patient.
Weight can be displayed in pounds or in kilograms. For privacy and convenience in use, the
scale features a remote display head which may be held by the operator, placed on a table or
other flat surface, or mounted on a wall. Both scale models have 2 wheels built-in for easy
mobility. Each scale can be powered using an AC adapter (included), or by 6 - AA
batteries (not included).
