    1.2 Installation Qualification and Operational Qualification ( IQ/OQ ) The calibration of the Model GS-800 Calibrated Imaging Densitometer can be validated by following the GS-800 Calibrated Densitometer Installation Qualification and Operational Qualification protocols. These protocols are available as an accessory to the GS-800 Calibrated Imaging Densitometer ( Catalog number 170-7956 ).

  • Page 8: Safety

    The Model GS-800 Calibrated Imaging Densitometer system uses high voltage and high current and should be operated with care at all times. To avoid shock, set up the GS-800 Densitometer in a dry area. Immediately wipe up any spilled solutions.

  • Page 9: Section 2 Setting Up

    1. Carefully lift the Model GS-800 Calibrated Imaging Densitometer out of the shipping carton and place it on a stable, dry, flat surface. The chassis of the Model GS-800 Calibrated Imaging Densitometer attempts to conform to any uneven surface. This may result in a poor-quality scan.

  • Page 13: Section 3 Installation

    Section 3 Installation 3.1 About SCSI Devices The Model GS-800 Calibrated Imaging Densitometer is a Small Computer System Interface (SCSI) device. It communicates with your computer by using the SCSI-2 standard. The SCSI communication standard allows you to connect more than one peripheral device to the same port of your computer in chain fashion.

  • Page 14: Checking The Terminators

    There should be two terminators in a SCSI chain. It is best to place the terminators at each end of the SCSI chain. The GS-800 Calibrated Densitometer has a built-in active terminator switch for you to turn on and off. Number 1 represents active terminator and number 2 represents terminator power.

    Densitometer to your computer, and lastly test the connection. SCSI Adapter Card The Model GS-800 Calibrated Imaging Densitometer requires a SCSI adapter card to work with your computer. The Densitometer driver software supplied with the Densitometer supports most Adaptec adapter cards.

  • Page 16: Testing The Densitometer

    Connect the Densitometer to the Computer With settings on the Densitometer and card correctly set and the interface card properly installed in your computer, you can now connect the Densitometer and the computer, as follows: 1. Ensure that the Densitometer’s SCSI ID is properly set. Determine which SCSI ID numbers are already assigned and which numbers are free.

  • Page 17: Section 4 Operation

    Transparency Module The Transparency Module (Figure 2.2) is secured to the Model GS-800 Calibrated Imaging Densitometer by two elongated hinges at the rear of the Densitometer. This Transparency Module should be lowered onto the Densitometer base for reflectance and transmittance scanning.
  • Page 18 Indicator Lights The indicator lights (Figure 2.2) are located on the front left side of the Model GS-800 Calibrated Imaging Densitometer cabinet. This panel consists of two lights that indicate the status of the unit.

  • Page 19: Start-Up

    For optimum performance, allow the Densitometer to warm up for five minutes after power-up. The Model GS-800 Calibrated Imaging Densitometer is now ready for use. 4.3 Reflective Scanning To scan a reflective sample: 1. Raise the Transparency Module.
  • Page 20 For more information about scanning operations and options, refer to the Quantity One software manual. Note: The OD values for the Transparency step tablet are included on a separate sheet with this Manual and are also on the Decal pasted on the right side of the instrument. If for any reason these values are lost contact Bio-Rad Technical Service.
