The M-35 is a fully scaleable 3 1/2 digit process meter for process signals. It is powered from 10-30 Vdc, so that it can run off batteries. Power and signal are isolated to 750 Vac to facilitate panel design, with no worries about ground loop errors. A detachable screw terminal connector provides a benefit rarely found on meters of this size.
Small size, low weight, and isolated DC power make the M-35 ideal for portable test equipment.
The above diagram for a typical pressure monitoring / manometer application shows how simple the M-35 is to connect. The same DC source powers the transducer and meter. Only three field wires are required.
A removable screw terminal is standard. The connector pin assignments as well as the zero and span adjustments are clearly labeled on the back of the meter.
