The Martel Electronics LC-100 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 LC-100
has the highest accuracy in its class.
Unique 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 LC-100 way beyond similar instruments.
The Martel LC-100 can simulate, power, and measure two-wire transmitters.
With automatic Step and Ramp functions, the LC-100 enables remote calibration
of 4-20 mA devices.
