  Section 2System Overview

  2.1 Introduction

  The Model 680 and Model 680 XR Microplate Readers are an
  eight-channel, vertical pathlength photometerthat measures
  absorbance of the contents of 96 well mictotitration plates. They
  can perform single or dualwavelength measurements, and can report
  absorbance values to three decimal places.

  The Model 680 and 680 XR Microplate Readers can be programed by
  entering commands through the keypadto define plate reading
  conditions and data analysis conditions as a protocol data, and
  select report types. Aprinted report is produced by an optional
  on-board thermal printer or external printer. An optional incubator
  isalso available.

  The Model 680 and 680 XR Microplate Readers feature a built-in
  RS-232C serial interface device for conve-nient computer
  interfacing. The Microplate Manager software for personal computers
  offers a complete analy-sis program. Microplate Manager supports
  Windows 95, Windows NT and Windows 2000.

  Microplate Manager Version 5.2.1 added support for the Model
  680XR reader.

  2.3 Product Configurations

  The Model 680 Microplate Reader is available in four
  configurations.

  2.4 Regulatory Notices

  This instrument is designed to meet Class A emissions and
  immunity levels of EN61326 product family stan-dard for CE mark.
  This rating requires that it only be used in a laboratory
  environment.

  This instrument is designed and certified to meet EN61010
  requirements which are internationally acceptedelectrical safety
  standards. Certified products are safe to use when operated in
  accordance with the InstructionManual. This instrument should not
  be modified or altered in any way. Alteration of this instrument
  will result invoiding of the manufacturers warranty, void
  regulatory certification and create a potential safety hazard.

  This equipment has been tested and found to comply with the
  limits for Class A digital device, pursuant to Part15 of FCC rules.
  These limits are designed to provide a reasonable protection
  against harmful interferencewhen the equipment is operated in a
  commercial environment. This equipment generates, and can
  radiateradio frequency energy and if not installed and used in
  accordance with the Instruction Manual, may causeharmful
  interference to radio communications. Operation of equipment in a
  residential area is likely to causeharmful interference in which
  case the user will be required to correct the interference at their
  expense.

  2.5 Product Overview

  2.5.1 Calculations

  The Model 680 and 680 XR Microplate Readers uses Beers Law to
  calculate the absorbance value of each well. Beers Law states that
  absorbance is equal to the Log10 of the ratio on the baseline
  measurement intensity (Io) to the Sample measurement intensity
  (I).

  Beers Law: Absorbance = Log10 (Io/I)

  Before measuring the plate, the reader takes a reading for all
  eight photodiode channels. These values are recorded as the
  baseline measurement (Io) values for each channel, respectively.
  The reader then records the sample measurement (I) value for each
  well, and calculates the absorbance using these values.
  Chan-nel-to-channel error is significantly reduced because the Io
  value for a given channel is used only in deter-mining the
  absorbance of the wells of that channel.

  2.5.2 Limits

  The Model 680 and 680 XR Microplate Readers display absorbance
  readings with absolute values up to 3.500. Absolute values greater
  than 3.500 are out of range and are displayed as either *.*** or
  -*.***.

  2.5.3 Memory Backup

  The battery backup provides memory even after the reader is
  turned off. The following information will be saved in memory until
  new reading parameters are set by the user or a new plate is read
  by the instrument. Note: If reading a new plate is aborted before
  it is finished, all the previous plate reading date will remain in
  memory and none of the new data from the new plate is retained.

  1. 10 latest plate reading data for End point protocol

  2. 2 latest sets of Kinetic plate reading data (maximum 30
  series of readings for each Kinetic)

  3. End Point and kinetic protocol data

  4. A set of Checkmark protocol data and the latest set of
  Checkmark read data

  5. 8 wavelength values for filters

  6. Laboratory name

  7. 2 security passwords (Administrator and Common user)

  The first time the instrument is turned on, or after a battery
  replacement, the following default information will hold in
  memory:

  1. Both Administrator and Common user security password are set
  to 00000

  2. Laboratory name is Bio-Rad Laboratories

  3. All wavelength values of the filters are set to — nm

  4. The date and time of the calendar chip are set to 1 day, 1
  month, 00 year, 0 hour and 0 minutes

  5. None of the plate reading data is available

  6. End Point protocol is chosen and the protocol number is set
  to #1

• System Overview

  2.5.4 Reports

  Eight types of reports for End Point protocol can be generated
  by the Model 680 Microplate Reader:

  1. Raw Data Report2. Absorbance report3. Limit Report4. Matrix
  Report5. Cut Off report6. Curve Fit Report7. Concentration Report8.
  Difference report

  2.5.5 RS-232 Interface

  The Model 680 Microplate Reader has a built-in RS232C interface
  (9 pin D-sub connector). This allows external computers to control
  the instrument. When an external computer is in control of the
  microplate reader, the printer and the keypad keys (except
  Start/Stop) are automatically deactivated and the display will
  indicate Remote Mode.

  The reader will remain in the remote control mode until it
  receives RL command from the host computer or until the Start/Stop
  key is pressed.

  RS-232 communication parameters are as follows:

  7.6 Firmware

  7.6.1 General

  1. Downloading firmware is achieved through a PC (Windows 95,
  NT, 2000, XP) and an RS-232 cable.

  2. The communication requirements are as follows:

  RS232CPort: COM1Baud Rate: 9600, 57600Data: 8 bit 1 stop

  3. The downloading program and additional files are required for
  downloading:

  m680_up.exe mscomctl.ocxcomdlg32.ocx msvbvm60.dllmscomm32.ocx
  asycfilt.dllcomcat.dll mci32.ocxoleaut32.dll
  olepro32.dllvb6stkit.dll

  4. The current firmware files are:

  M680_V171OL.txt for Original Lens models (SN 10001 through
  10735)M680_V171NL.txt for New LCD models (SN 10736 through
  13850)M680_V171.txt for Backlit LCD models (SN 13851 and higher)
  M680_V171.txt for Chinese version instrumentsM680XR_V163-XR.txt
  (for Model 680XR readers)

  5. When updating firmware versions 1.60 and earlier with
  m680_up.exe, plate reading results, security password, Checkmark
  reference values, Checkmark reading results and laboratory name
  will be lost. Protocol settings (except for #5-8) and filter
  wavelengths will be retrieved and restored in the update process.
  Date and time will need to be reset.

  6. When updating firmware versions 1.61 and later with
  m680_up.exe, all data and settings except for security password,
  Checkmark reading results, Protocol settings (except for #5-8) and
  Plate Reading results (#5-8) be retrieved and restored in the
  update process. Date and time will need to be reset.

Назначение

Фотометры для микропланшетов Mark исполнение iMark (далее по тексту — фотометры) предназначены для измерений оптической плотности в лунках стандартного 96-луночного планшета при проведении различного рода исследований (иммуноферментный анализ, биохимические исследования).

Описание

Принцип действия фотометра основан на измерении оптической плотности анализируемых проб в 96-луночных планшетах. Для коррекции нестабильности источника света используется опорный световой канал. Выделение необходимой длины волны в световом потоке производится при помощи узкополосных интерференционных фильтров.

Световой поток падает через верхний блок линз сверху, на лунку с измеряемым образцом. Ослабленный пробой световой поток регистрируется фотодетектором, расположенным под образцом. В момент измерения каретка с микропланшетом перемещается относительно светового потока.

Фотометр имеет встроенный интерфейс USB, что позволяет работать как автономно, так и под управлением внешнего компьютера.

Защита от несанкционированной модификации обеспечивается конструкцией фотометра.

Общий внешний вид фотометра и схема пломбировки показаны на рисунке 1.

Программное обеспечение

предназначено для управления фотометром, обеспечения функционирования интерфейса, обработки информации, полученной в процессе проведения измерений, хранения результатов измерений.

Идентификационные данные (признаки) метрологически значимой части программного обеспечения фотометров указаны в таблице 1.

Защита программного обеспечения от непреднамеренных и преднамеренных изменений соответствует уровню «средний» в соответствии с Р 50.2.077 — 2014.
