1.4.2 Instrument Positioning

The Sentry Plus unit contains a graphic display for direct readout of measured parameters. The
optimum angle for viewing is slightly down and about 10 degrees either side of center.
bench operation the front flip feet should always be used to angle the instrument up. In bench or
rack mount applications the instrument should be positioned with consideration for ample air
flow around the rear panel fan ventilation hole. An open space of at least 3 inches (75mm) is
recommended behind the rear panel. Testing should be performed on a non-conductive surface.
An ESD mat is not a recommended test platform.

1.4.3 Power Requirements

The Sentry Plus instrument can be operated from a power source of 90 to 132V AC or 198 to
250V AC. Power connection is via the rear panel through a standard receptacle. Before
connecting the 3-wire power cord between the unit and AC power source, make sure the voltage
selection switches on the rear panel (Figure 1-5) are in accordance with the power source being
used. For a 90-132V source, use a 3.15A 250V fuse. For a 198-250V source, use a 1.6A 250V
fuse. Always use an outlet that has a properly connected protection ground.
