Using the Service Monitor
The monitor can be used as a bench instrument, either flat standing or inclined using the elevating
front feet. The monitor can also be used as a field service instrument while left in the ‘Ever-ready’
case. It can be operated in any position convenient to the operator. See the
Caution under
Ventilation, earlier in this chapter.
