LC100 Precision Loop Calibrator.
LC100 Precision Loop Calibrator provides significantly extended performance when compared to any competitive calibrator. With an accuracy of 0.015% of reading, with 0.001 mA resolution,
the LC100 Loop Calibrator has the highest accuracy in its class. 
Features such as a "% Error" function, which eliminates manual error calculation and allows the display of the actual versus ideal error at any calibration point, put the LC100 Loop Calibrator way beyond similar instruments.
The LC100 Loop Calibrator can simulate, power, and measure two-wire transmitters. 
With automatic Step and Ramp functions, the LC100 Loop Calibrator enables remote calibration of 4-20 mA devices.
