2.11 ELECTRICAL MONITORING SYSTEM OPERATION
VOLTAGE is displayed both graphically and digitally. Full color range
marks provide a quick reference for fast analysis of voltage levels. As
voltage rises, the graph size increases proportionately.
Voltage Alert: Your system has a built-in warning system that flashes
the display when system voltage is out of nominal range (either too low
or too high) .
AMPERAGE is displayed both graphically and digitally. Full color range
marks provide a quick reference for fast analysis of amperage levels.
As amperage rises, the graph size increases proportionately.
The digital readout displays amperage at 1 amp resolution. This is
useful for troubleshooting.
The amp system functions as an 'alternator load meter' displaying
current flow FROM the alternator TO the aircraft electrical system
allowing you to see if a load (such as pitot heat) is really drawing current
when turned on. You should see an increase on the amp display when
you turn on a load, such as pitot heat for example. This tells you that the
pitot heater is drawing power and is probably OK. By verifying that
voltage remains the same, then it can be assumed that the alternator is
supporting the additional load. A very handy feature for in-flight testing /
verification of electrical loads and the alternator charging system.
Amps Alert: Your system has a built-in warning that flashes the display
when the alternator does not produce power for the electrical system.
