Resistance measurements:

An example of how to make AC voltage measurements is shown in the diagram below. Once again, the red and black test leads are connected to the '+' and '-' sockets respectively. The range selector is set to AC, 10V. The pointer is reading midway between 0 and 2 and the indicated reading is 1V, approximately.

RESISTANCE MEASUREMENTS

Examples of how to make resistance measurements are shown in the diagrams below. In all three cases, the red and black test leads are connected to the '+' and '-' sockets respectively. Before making any measurements it is absolutely essential to zero the meter. This is achieved by shorting the test leads together and adjusting the 'zero adj' control until the meters reads full-scale (i.e., zero on the ohms scale).

In the first diagram, the range selector is set to OHM * 1. The pointer is reading midway between 0 and 10 and the resistance indicated is approximately 5Ω.
In the second diagram, the range is set to OHM* 10. The pointer is reading exactly 30 and the resistance indicated is 30*10 or 300Ω.
