Section 4. Quickstart Tutorial 4.2.2 Hardware Setup Note The thermocouple is attached to the CR3000 later. 4.2.2.1 Internal Power Supply With reference to figure Power and RS-232 Connections (internal-power supply) (p. 44), some CR3000 dataloggers are shipped with a power supply internal to the removable base. This internal power supply may use alkaline batteries or sealedrechargeable batteries. For more information and installation procedures, refer to the Alkaline Battery Base (p. 84) or Sealed-Rechargeable Battery Base (p. 85) section. When the base is in place, move the on/off switch on the side of the CR3000 base to the On position. If using the sealed-rechargeable battery base, remember not to leave the CR3000 running too long without connecting the primary power source. Figure 13: Power and RS-232 connections (internal-power supply) 4.2.2.2 External Power Supply With reference to the figure Power and RS-232 Connections (external power supply) (p. 45), 1. Remove the green power connector from the CR3000. 2. Verify that the red wire on the PS100 is attached to a PS100 12V terminal, and the black wire is attached to a PS100 G terminal. 3. Verify the on/off switch on the PS100 is in the Off position. 4. Attach the red wire from the PS100 to the terminal labeled 12V on the green connector. 44
