    2.3 Overall Principles of Operation ™ This section of the manual describes the principles of operation of the DINAMAP Compact monitor. The section is arranged to give an overall description of the instrument, the following sections then detail each of the functional systems.

  • Page 20: Temperature System (Ts & T Models Only)

    counter IC36 to provide the 1.23 MHz ADC clock. Communication between microprocessor IC22 and all bus devices is provided by a 24-bit address bus, 8-bits data bus and the three wire serial peripheral interface (SPI) bus. The system processor is equipped with a watchdog timer and reset circuit. The system program is stored in a 4 Mbit FLASH memory IC28 as 512k by 8 bit words.

  • Page 21: Nibp System

    Compensation for drift in accuracy of the system is achieved by the unit recalibrating itself on switch on and after each measurement and at ten-minute intervals. Calibration is achieved by measuring two points on the high precision resistor chain of RV3, R70, and R74-77 which equate to 10°C and 37°C. Any changes in VREFI or voltage to frequency transfer characteristic can therefore be accommodated within reason.
  • Page 22 Deflate and Dump valve control signals are also generated by latch IC3 (Main Board) and passed to the GAL IC1 (power supply board). Pump motor current is sensed in R31 and amplified by IC4. This is routed to the system processor as PUMPC and also compared to a reference to produce an over current input signal to the GAL.

  • Page 23: Spo 2 System (Ts & S Models Only)

    buffered by IC12 to produce TH_VREF which can be measured by the system processor via multiplexer IC20 and ADC IC23. Upon clearance of the overpressure condition the Main Board system processor can reset the overpressure latch in GAL IC1 on the PSU Board, by asserting PNEU_RESET signal high, in order that another determination can be carried out.

  • Page 24: Audio Amplifier

    If there is no valid external DC line supply applied to the monitor, the monitor will default to use the battery. DC from the rechargeable battery arrives on thermal fuse FS1, from where it is routed to the source of TR2, a p-channel FET under the control of TR3.

  • Page 25: User Controls

    Communications signals use the RS232 bi-directional serial format. Digital TTL level signals from the system processor are converted to RS232 level signals on the power supply board by IC13, which generates the necessary positive and negative voltage swings. In addition, inverted TTL data transmit and receive lines are provided.

The trimmed voltage is nominally set to -9.6V and may be measured across TP1 and TP2 of the switchboard. 2.4.11 Printer The monitor employs an Axiohm HPT4050 thermal printer module, fitted to the printer board, which contains the interface electronics.

  • Page 27: Maintenance

    3 Maintenance This section of the manual contains four parts: The first covers general maintenance functions, which can be performed without disassembly of the monitor. The second covers use of the built-in Service Software. The third describes how to calibrate the NIBP and overpressure detection of the monitor, or check their calibration.

  • Page 28: Care Of The Storage Battery

    ™ The adult DURA-CUF range supplied for use with this Monitor may be cleaned by hand washing in warm soapy water. Care should be exercised, however, to ensure that no water enters the cuff or cuff hoses at any time. In the event water accidentally enters the cuff, passing air through the cuff will dry it.

  • Page 29: Service Modes

    3.2 Service Modes There are three different service modes, each offering different levels of access to the monitor’ s set-up and calibration. These modes can be accessed using the rotor control and display panel. The modes are: 1.
