    1.2 Unpacking Remove the packing list and verify that all equipment has been received. If there are any questions about the shipment please call Martel Electronics at 1-800-821-0023. When the ship- ment is received inspect the container and equipment for any signs of damage. Note any evidence of rough handling in transit.
  • Page 5 Battery CE Complies with European Union Directives Double Insulated Electric Shock Fuse PE Ground Hot Surface (Burn Hazard) Read the User’s Manual (Important Information) Canadian Standards Association The following definitions apply to the terms “Warning” and “Caution”. • “Warning” identifies conditions and actions that may pose hazards to the user.
  • Page 6 Use the calibrator only as specified in this man- ual, otherwise injury and damage to the calibra- tor may occur. Warning To avoid possible electric shock or personal injury: • Do not apply more than the rated voltage. See specifications for supported ranges. •...

  • Page 7: Nomenclature

    • To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator appears. Caution To avoid possible damage to calibrator or to equipment under test: • Use the proper jacks, function, and range for your measurement or sourcing application.

    3. Getting Started A. Battery Save Feature After unpacking the LC100, it should be ready for use. A 9 volt alkaline battery comes pre- installed. The “Battery Save” feature is enabled and set to 30 minutes in case the unit is acci- dentally turned on in transit.

  • Page 9: Basic Operating Modes

    950 ohms. In most cases this should not be a problem when calibrating Non-HART™ compatible products. 4. Basic Operating Modes The LC100 offers 4 modes of milliamp opera- tion and one voltage measure mode. The fol- lowing text and figures explain the various oper- ating modes:...

  • Page 10: Milliamp Source

    LC100 is sourcing 4 to 20 mA into a device under test. Figure 3 - Sourcing 4 to 20 mA 1) Turn on the LC100. It will default to the mA source mode. 2) Connect the device to be calibrated.

  • Page 11: Milliamp Simulation

    Refer to the Auto Modes Section of the manual for more information. B. Milliamp Simulation Figure 4 shows how to connect the LC100 to act as a two-wire transmitter using an external power supply. In this application the power for...

  • Page 12: Milliamp Measure With Loop Power

    But in this case the device under test is a two- wire transmitter that requires an external power supply to generate an output current. In this application the LC100 will supply 24 volts to the loop while simultaneously measuring the result- ant loop current. To turn on the loop power...

  • Page 13: Advanced Operating Modes

    Figure 6 - Measuring 0 to 28 VDC 5. Advanced Operating Modes A. Auto Step/Ramp Mode The LC100 has the ability to step the mA output in 25% steps automatically in 5 second inter- vals. It can also ramp the mA output from 4 mA to 20 mA then back to 4 mA in a linear fashion automatically.

  • Page 14: Percent Error Mode

    % error display. The procedure is as fol- lows: 1) Connect the LC100 to the unit under test. 2) Place the LC100 in one of the mA output modes (source or simulate). 3) Adjust the LC100 to the desired output.

  • Page 15: Min/Max Datalogging

    % display will return to normal operation. C. Min/Max Datalogging When the LC100 is in any of the measure modes (mA, mA w/loop power or voltage) it will continuously monitor and store the minimum and maximum values for that particular input mode.

  • Page 16: Maintenance

    Because of this protection no mainte- nance is required. C. Calibration The LC100 is designed to hold its rated accura- cy for a minimum of one (1) year. It is therefore recommend that an annual re-calibration be done to ensure operation within specification.
