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.
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.
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.
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.
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.
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.
viewing angle or contrast of the LCD display. 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.
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.
™ 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.
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. The “ Clinician Menu” mode, allowing: setting of temperature units, checking NIBP and temperature calibration dates, setting the alarms into “...

Selection of OK saves changes and returns to the Service menu.
™ DINAMAP COMPACT Calibration check or re-calibration 3.3.2 NIBP Calibration ™ The following section describes how to perform NIBP re-calibration on a DINAMAP Compact Vital Signs ™ Monitor. Refer also to the previous section for details on checking of the DINAMAP Compact calibration.
™ The DINAMAP Compact requests that the pressure be set to 0 mmHg. No action should be necessary other than to verify that the calibration pressure measurement system still displays 0 mmHg (0 mBar). ™ XI. Approximately 6 seconds later, the DINAMAP Compact beeps and prompts for the pressure to be set to 200 mmHg.
VI. Select “ Check” from the NIBP service menu. VII. Inflate the system and observe the calibration pressure measurement system - the pressure will be seen to rise and, at the “ Pop Off Pressure” , will immediately deflate, with the pump ™...
3.3.5 Predictive Temperature Calibration Check ™ The predictive temperature calibration of the DINAMAP Compact monitor should be checked every 12 months or when there is doubt about the validity of the temperature readings. The temperature calibration plug (part number 320-635) may be used to check the calibration of the temperature detection circuits within the monitor.

Before the panel can be separated from the case, it is necessary to disconnect the switchboard cable, temperature probe cable and SpO sensor cable if fitted. The switchboard ribbon cable plugs into socket PL10 on the Main Board via a ferrite, which clamps the cable to the front of the chassis metalwork.
The cable from the Temperature probe socket plugs into connector PL14 on the Main Board and is easily removed. The SpO cable runs from the small front panel connector printed circuit board to another small PCB with ™ integral connector attached to the Nellcor Puritan Bennett module.
3.4.3 Removal of the Chassis The chassis contains the Main board (revision 04 and earlier), the Power Supply board and the Pump ™ assembly. SpO equipped models also have the Nellcor Puritan Bennett module fitted in a shield case fixed to the front plate of the chassis. This is connected to the Main Board via the ribbon cable to SK13. Unplug this connector.
3.4.4 Removal of the Main Board and Power Supply board from the chassis To remove the Main and Power Supply boards from the chassis, the valve control and pump connector must first be removed. This is visible through the hole in the rear of the chassis. The chassis spade terminal must also be removed.
To separate the boards, use a fine nosed pliers to pinch the tip of the nylon pcb spacer while gently pulling the boards apart. Note that this will result in the loss of the user settings. To avoid damage to the PCB interconnection, ensure that the boards are not tilted or twisted relative to each other as they are separated.
