OHMMETER is used to check resistance on
static circuits or voltage by simply probing the
connection of the circuit being tested.
OHMMETER is used like a standard Ohmmeter
and measures total circuit resistance from the
source battery accurately with the Aux. Ground
lead whether there is voltage feeds on the
circuit or not. In this mode, the
Maestro
™
display
will show:
The circuit resistance will be calcuated even with voltage applied to the circuit. To accu-
rately test the power and ground feed resistance, the component must be removed from
the circuit first. Simply unplug any component, relay or module on the circuit, contact the
probe tip to the circuit and view the circuit resistance.
Maestro
™
has a feature located in some modes that show an arrow in the upper right
corner of the screen. If this arrow is present, pressing either the up or down arrow as
indicated by the state of the arrow will take you to special functions or back to the main
screen. In Ohmmeter, pressing the up arrow will take you to the Feed Test.
