Chapter 6 CAUTION Turning on the AC filter may reduce or distort the QRS amplitude. Problem : Electromyogram is interfering. Cause : Electromyogram may interfere depending on the electrode placement. Solution : Relocate the electrodes where the electromyogram will not interfere.
Page 51
Troubleshooting “CVA” is displayed. Problem : The ECG waveform is superimposed on the respiration waveform. Heart rate is equal to the respiration rate. Cause : ECG artifact is interfering. Solution : Change the electrode position where it will not be affected by ECG artifact.
: On the DS-5300, HC-530 is set to OFF for the “MODULE CONFIG.” in the preset menu. Solution : Set HJ-500 to ON for the “MODULE CONFIG.” in the preset menu of the DS-5300. For procedures, refer to the operation manual for the DS-5300 Readings drift constantly without any physiological causes when electrodes are applied to the patient.
Page 53
Troubleshooting Readings change suddenly without any physiological cause. Cause :Artifact due to patient movement. Solution :Recalibrate and reapply electrode to the skin, possibly, selecting a new measuring site. Noise appears on the readout. Cause :Interference from nearby equipment. Solution :Increase the distance from the interfering equipment. Monitor not operational.

Circuit Description Circuit Description(HC-530) ●HC-530 Theory of Operation The HC-530 is a transcutaneous oxide/carbon dioxide partial pressure (tcpO2/pCO2) module that operates with the DS-5000 series monitor system. The HC-530 module must be inserted into the IB-5006 for operation. Only one HC-530 module can be installed into a system. The HC-530 module consists of an I/F board (PCB-6597) common to other modules and a dedicated TCP board (PCB-6619).
Chapter 8 ●PCB-6619(TCP BOARD) The TCP board is dedicated to the HC-530 module. The board contains an input amplifier, a multiplexer and A/D converter circuit, an overheat detector, a heater current limiter, a heater voltage controller, and a heating controller. Input Amplifier The input amplifier amplifies the input signals from the input connector and sends the amplified signals to the multiplexer.
Page 79
Circuit Description Heater Voltage Controller The heater voltage controller contains the DC/DC converter (IC9) that converts the +5 V input voltage to a voltage within a range between -15 V and -10 V. When the electrodes are not heated, this circuit regulates the heater voltage to -10 V.
Chapter 8 ●PCB-6597 (I/F BOARD) The I/F Board has an A/D converter and creates measurement values for the monitor. Waveform measurement data are sent to the monitor through HDLC protocol at 1 Mbps. For control of all of the functions, the following devices are required: HD6417032F20 Clock: 8 MHz Peripheral Devices: SCA...
Page 81
Circuit Description 5.WDT (Watch Dog Timer): Reset IC The I/F Board contains a reset IC that includes watch dog timer function. This monitors power voltage, and various software operations. If 1.6 seconds pass without proper communication to the WDT, this IC outputs a reset signal. The CPU power voltage cannot drop below 4.65 VDC or the WDT will reset.
Chapter 8 ●Electrode Error Processing(HC-530) The HC-530 module has a variety of electrode checking functions. If any error other than the TEMP error occurs, this module stops heating of the electrodes, clears the measurement values on the monitor, and displays an error message on the monitor.
Page 83
Circuit Description ERROR FACTOR SIGNAL RANGE ERROR ・ This error occurs when neither the pO2 or pCO2 signal comes into the specified signal range within 1 minute after completion of heating check during calibration. ・ This error does not occur if either the pO2 or pCO2 signal comes into the specified signal range.
