The DMS-20PC-2-LM’s unique power-supply circuitry allows a single model to operate from either 240 to 310Vac with 50/60Hz inputs or from 85 to 140Vac with 400Hz inputs. The meter requires no external components or auxiliary power for full opera- tion! Its large, 0.37"/9.4mm, bright red LED display is easily readable under virtually all lighting conditions. DMS-20PC-2-LM employs half-wave sinusoidal averaging (rms calibrated) to achieve a display resolu- tion of 1Vac over its full operating range. Packaged in a red-filter case with a built-in bezel, the meter is epoxy encapsulated for ruggedness. This low-cost, extremely versatile digital voltme- ter is ideal for use in emergency power equipment, 277Vac fluorescent lighting systems, 400Hz aircraft installations, and any other application requiring accurate, high-voltage or high-frequency, ac line monitoring.
