The Weston 2470 Series are a family of
4½-digit, high-accuracy, line-powered, single-range panel
meters. The series offers a high-brightness LED displays with five
DC ranges from 20mV full scale with 1µV resolution, to 200V
full scale with 10mV resolution.
All models provide automatic zero calibration,
accuracy of ±0.005% rdg. ±2 digits, and an auxiliary
power supply output of ±12VDC or + 5VDC. Options include
a parallel-BCD output with 200V RMS isolation (Models 2472) as well
as direct readout in engineering units such as psi, pH, °C,
or oF (all models). Any model may be adapted to 4-20mA current-Loop
and 1-5V voltage loop data transmitters.
