2 Introduction and installation
This installation guide will show the basics of connection and setup of the HRB base
bench scales shown in Figure 2.1.
Figure 2.1 HRB large and small capacity bench scale bases
The HRB base uses a family of digital load cells. The bases are constructed of die cast
aluminum, with stainless steel load-receiving platters. The 35kg and 80kg bases have
a rectangular stainless steel platter of the same dimensions as the base. The 1 and 5kg
models have a round weight platter six inches in diameter. The optional draft shield for
the low capacity bases (1kg and 5kg) is shown in Figure 2.1.
Base size (inch / cm) Platter size (inch / cm) Scale capacity
