Martel LC-100 4 - 20 mA Current Loop Calibrator. High accuracy of ±0.015%. High resolution of 0.001mA/0.001V. % Error Function eliminates manual error calculation. Extended adjustment range - digital knob and user-selectable decade output allow both large and incremental (0.001 mA step) output changes. Reads 0 to 28.0 VDC. Built-in 250 ohm resistor facilitates calibration of HART devices. Loop power measurements. Simulates, Powers, and Measures Two-Wire Transmitters. Preset outputs (4, 8, 12, 16, 20 mA). Fuseless input protection. Includes neoprene sleve, NIST Certificate with calibration data.

The MC-1200 measures and sources T/Cs (13 types), RTDs (13 types), Ohms, current, voltage, frequency; source pulse trains. Isolated mA/V read-back circuit for complete transmitter calibration. Communication port compatible with both Fluke 700 Series and Beta Calibrator pressure modules. Built-in 24V supply can drive 4-20 mA lops up to 1000 Ohms. Direct entry of custom RTD coefficients (Ro, A, B, C). All source modes can be programmed with dedicated setpoints to speed calibration and linearity tests. Highest accuracy in class to 0.015% of reading. Meets CE requirements and is designed to IEC 1010 safety standards. Supplied in full rubber boot; optional carrying case available. Includes NIST Certificate with calibration data.
