Giraffe and Panda Scale (Shekel) Service Manual

Chapter 1: Functional Description

The Giraffe™ and Panda™ infant scale utilizes the latest developments in transducer technology and integrated circuits to provide a highly reliable and accurate weighing scale. The scale is built with two load cells and an electronic circuit, which calculate the weight value and communicate it to the bed unit (warmer or incubator) it is connected to. The scale is connected to the bed unit with a cable for data communication and getting power. GE scales that are sold in European Union (EU) member states have been designed and manufactured in accordance with the non-automatic weighing instruments (NAWI) directive, 2009/23/EC. These scales must be calibrated by an accredited local test authority. The bed service screen displays two scale parameters labeled SR and SC, which are related to the weight applied to the top of the scale. Note: •

The service screen displays SR and SC values only if the scale is connected to the bed unit prior to entering the service screen.

SR (Scale Counts Raw) The SR value represents the number of times the scale has been calibrated.

•

SC (Scale Counts Calibration) The SC parameter is the weight value after the scale’s digital processing of the applied weight. On a properly-calibrated scale, each SC count represents 1 g of applied weight. When a weight is placed on the scale, the SC value increases (1 count per 1 g of applied weight), and the increased value is added to the SC value when no weight was applied. For example, if the SC value corresponding to a no-weight condition is 10,0000, placing a 5 kg test weight on the scale results in an SC value equal to 15,000. SC values can range from 0 to 40,000, however, offset and correction factors limit this to a smaller range.
