    2. Quick Start Instructions A. Key Functions Function Input/Output Toggles the function selected from measurement mode to source mode. Pressing the “TC” or “Thermocouple” key toggles through all available TC types as well as direct mV output. Pressing the RTD key toggles through all available RTD types as well as direct ohms output.

    c. The next screen prompts you to enter the dwell time from 5 to 500 seconds. Simply enter a number in that range. d. Auto-step will begin. e. To exit auto-step press the “CE” key or enter a value. 4. Manual Stepping The PTC8001 can be manually stepped through all or some of the stored setpoints.

    Figure 1. B. Sourcing a Thermocouple Signal TC wire must be used to achieve an accurate calibration. Figure 2. Note: For best accuracy allow a 10 minute warm-up period after the PTC8001 is turned on. C. Measuring Temperature Using a Thermocouple Figure 3.

  • Page 12: Measuring Resistance (Rtds)

    D. Measuring Resistance (RTDs) When measuring resistance (ohms) there are 3 choices when using the PTC8001. The choices are 2-wire, 3-wire, and 4-wire measurements. While 4-wire offers the highest accuracy, most industrial RTDs are a balance 3-wire. Figure 4 shows how to hook up the PTC8001 for the 3 types of measurements.

    Measuring a 4 Wire RTD Figure 4. E. Sourcing Resistance Into a RTD Transmitter 1. As described previously in section A the PTC8001 can source resistance in a RTD Transmitter or measuring device. In many cases the unit under test will require a 3 or 4 wire connection to achieve best accuracy.

  • Page 14: Maintenance

    4. Maintenance A. Power Requirements The PTC8001 operates on 4 AA alkaline batteries or optional rechargeable Ni-Cd batteries. To replace the alkaline batteries or to install rechargeable batteries remove the two (2) screws on the rear battery door and lift the battery cover. When using Ni-Cd batteries the AC adapter will simultaneously power the PTC8001 and charge the batteries.

    4. If a blown fuse is found replace with the enclosed spare fuse. 5. To order more fuses contact Martel Electronics and order part number 3535039. C. Calibration The PTC8001 should hold its rated specifications for a minimum of one year. Given this, annual re-calibration is required for best performance.
