  • Page 5 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. • “Caution” identifies conditions and actions that may damage the instrument being used. Use the calibrator only as specified in this man- ual, otherwise injury and damage to the calibra- tor may occur.
  • Page 6 • Remove test leads from the calibrator before you open the battery door. • Inspect the test leads for damaged insulation or exposed metal. Check test leads continuity. Replace damaged test leads before you use the calibrator. • When using the probes, keep your fingers away from the probe contacts.
  • Page 7 Caution To avoid possible damage to calibrator or to equipment under test: • Disconnect the power and discharge all high- voltage capacitors before testing resistance or continuity. • Use the proper jacks, function, and range for your measurement or sourcing application. •...

    2. Quick Start Instructions A. Key Functions Function Input/Output Toggles the function selected from measurement mode to source mode. V/mA/Hz Selects between volts, mil- liamps, and frequency modes TC/RTD Selects between temperature modes either T/C or RTD. Ohms and mV ranges are also included in these functions.

    3. Connection Diagrams & Instructions A. Measuring High Voltage AC or DC 1. Select the Voltage Input Mode. Use the “Range” key to select either AC or DC input. 2. Connect the device to be measured as shown in Figure 1. ! WARNING ! When measuring high voltage be sure to use proper connections as shown in Figure 1.

  • Page 13: Measuring Current

    C. Measuring Current 1. Select the mA input mode. Note: To power the loop while reading current, select the “mAPW” mode. 2. Connect the device under test as shown in Figure 3. 3. Current can either be measured directly in mA or as a percentage such that 4 to 20 mA corresponds to 0 to 100%.

    Refer to Figure 10 for connection information. Figure 10. 4. Serial Communications The MC1000 calibrator is equipped with a RS- 232 serial communications port, which is locat- ed on the top of the case. Note: The user will require a special RS-232 cable to connect the calibrator to a computer or terminal.
  • Page 18 The MC1000 calibrator can be used with virtually any terminal emulation software. (i.e. Procomm or HyperTerminal) When connected properly, data will be transmit- ted as soon as the calibrator is turned on. The data transmitted to the terminal or computer will mirror that sent to the calibrators LCD display and will be updated approximately every 0.4...
