DATEL's new DMS-20PC-FM Series are the world’s smallest, self-powered, ac fre-

quency meters. Simply connect the ac line to the two rear input terminals, and the unit is

fully operational with no additional components or auxiliary power required! Two, 50/60Hz

models operate over input voltage ranges of 85-140Vac or 170-264Vac. A third, 400Hz

model operates over an input voltage range of 85-140Vac. Despite their small size (1.38"

x 0.88" x 1.0"), DMS-20PC-FM meters feature large 0.40"/10.2mm red LED's that can be

read easily from 15 feet away.
