2.4. Electrical
There are three types of electrical connections to the DLM: digital signal
input (and optional output), peak hold function selection, and DC power.
Signal Connection
The DLM is designed to operate with either professional balanced input
lines using a shielded twisted pair, or unbalanced lines using coaxial cable.
Wiring for each is shown in Figure 2-2. Signal connections should be made
to the corresponding terminal of the meter’s Euroconnector.
