The Martel  LC-110H  mA (loop) calibrator is designed to take the loop calibrator class to the next level. The LC-110H differs from the standard LC-110 in that it incorporates HART communications and supports a select set of the HART universal and common practice commands. This unique feature allows the LC-110H to be used as both a loop calibrator and communication tool.

General Features:

• Best in Class Accuracy at 0.01% Reading
• Small Rugged design operates on (6) alkaline AAA batteries
• Intuitive interface that features a Quick-Set Knob
• 24 VDC loop power with mA Measure Mode (-25% to 125%)
• Resolution of 1µA on mA ranges and 1mV on voltage ranges
• Built in selectable 250Ω resistor for HART communications
• Simple two wire connection for all measurements
• Auto Shutdown to conserve battery life (adjustable up to 30 minutes)
• Variable step & ramp time in seconds
• Adjustable span selection (0 to 20mA or 4 to 20mA)
• Valve Test (simulate defined mA values with % keys)
