VISHAY BLH 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 instruments. 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 ohm 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 excellent accuracy make the Model 125 Calibrator an excellent choice for calibrating, spot-checking or trouble shooting any electronic weigh system.
