 Precision Current Loop Calibrator With Hart Communications/Diagnostics
LC-110H Precision Current Loop Calibrator with HART Communications / Diagnostics

  • 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)
  • More information
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. 

In the communicator mode the user will be able to read basic device information, perform diagnostic tests, and trim the calibration on most HART enabled transmitters. In the past, this could only be done with a dedicated communicator, high-end multifunction calibrator costing thousands of dollars, or a laptop computer with HART modem. The LC-110H will allow many more technicians to service and support HART devices.

  • Valve Test (simulate defined mA values with % keys)
  • More information
The Martel LC-110 mA loop calibrator features a user friendly interface with dedicated buttons and a rotary encoder (Quick-Set Knob). This combination dramatically reduces the time it takes to measure, or source voltage or current and power up a loop. The Quick-Set knob features an integral push button that you press to enter a selection. A dedicated menu key brings up a list of functions. The Quick-Set interface highlights an item on that list, and then pressing the knob (clicking it) selects that item to drive further in the menu or implement the task at hand. The “Menu/Exit” key is used to go back to the previous menu or exit from menu structure into measure/source mode. When used a mA calibrator only, there are dedicated keys for automatic step and ramp generation as well as keys to perform a quick zero and span (4 mA, 20 mA, and 25% steps). The rugged case is contoured to easily fit a technician’s hand and the large backlit graphics LCD is best in class.
Martel MS-420 Mini-source portable loop calibrator 

Loop Calibrator
MS-420 Loop Calibrator - Mini-source Portable Loop Calibrator

  • Calibrates Chart Recorders
