Low Voltage
Settings
Component Resistance
The
Component Resistance
setting is automatically determined when the
Learn Components
setting is turned ON
,
and components are sensed in the cable. The tester sets component
resistance
to 20% less than the lowest resistor value found in the cable. The figure below shows
the
Component Resistance
setting in relation to the other settings. This affects the low voltage
test.
When to Change Component Resistance
In some rare instances, you may need to change the component resistance by editing a loaded
test program. Change the component resistance:
If you have components with resistance so low, you lose the “measurement window” between
Connection Resistance
and
Component Resistance
settings. In this case, you potentially
have two options:
Option 1:
You can raise the
Connection Resistance
and
Component Resistance
settings to test components as connections.
Option 2:
If cable connections have more than .1Ω of resistance, lower both
the
Connection Resistance
and
Component Resistance
settings below the cable
connection resistance. Wires and components will be measured as components.
If you have large capacitors (values greater than 10 microfarad). In this case, you may need
to change the
Component Resistance
setting below 1KΩ so the capacitors will not be
reported as shorts.
