LC-110 Precision Loop Calibrator

Rapidly dial in precise values with one hand for the troubleshooting and tuning of process control loops

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.
