Setup Options
You can configure the 248 by choosing units of measurement, setting
reference ranges and so on. This is covered in Section 5, Configuring the
System. Section 5 also gives recommended settings where applicable.
You can, of course, use the 248 using the default (factory set) options and
values. These are given below.
