There are 6 labelled terminals on the UTS Black Box 1 which allow you to make external connections.
You will be given a UTS Black Box 1, which contains an unknown network of resistors and diodes.
Example
1. Measure the resistance between UTS Black Box 1 terminals 2 and 1, ensuring that the black lead of the DMM goes to terminal 1.
Figure LT1-1 below illustrates a schematic representation of the UTS Black Box 1:
