125 Pocket Calibrator
Model 125 Pocket Calibrator is a portable, lightweight
simulator designed to supply millivolt-per-volt level signals
for testing, calibrating, and troubleshooting load cell/scale
indicators. Precise output references for 0, 1, 2, or 3 mV/V
are achieved by using a metal film resistor network,
discrete wire wound resistors, and a 2-pole, 4-position
rotary switch.
The 350 Ω input and output impedance matches typical
strain gage devices. Four permanent binding posts,
integral to the rugged palm-size case, provide connection
points for the indicator or transmitter.
Model 125 units substitute for platform or scale
transducers. Lightweight construction, compact size,
and good accuracy make the Model 125 Calibrator an
excellent choice for calibrating, spot-checking, or trouble
shooting any electronic weigh system
