3. ECG test (1) Set the ECG simulator as follows: Heart rate: 80bpm, ECG gain: 1mV (2) Connect one end of the ECG cable and leadwires to the ECG connector of the monitor and the other end to the simulator. (3) Confirm if patient simulator has been connected properly to the monitor. (4) Observation: ECG lead II is displayed in the ECG channel, without noise. Heart rate display: 80±2bpm. When R wave appears, you can hear a “beep”. (5) Check every ECG lead to see if there is any ECG waveform and noise interference. (6) Adjusting ECG gain to be 2mV, observe if there is any change in ECG waveform. (7) Unplug the RA from simulator, then observe if the screen prompts “lead off”. (8) Reconnect RA lead. (9) Set 1mV calibration in the ECG setting menu, and observe if a 1mV calibration square wave is overlapped over the ECG waveform. (10) ECG test is complete. 4. Respiration test (1) Connect ECG cable to the ECG socket properly and set the simulator as follows: respiration baseline resistance: 500 Ohm, Respiration Delta R: 0.5 Ohm, Respiration lead: I or II. Respiration rate: 30bpm (2) Set monitor respiration lead to be RA-LA or LL-RL and set respiration waveform channel. (3) Observe if respiration parameter area displays reading 30±2bpm, waveform channel displays respiration waveform. (4) Change monitor respiration lead and observe the above parameter and waveform. (5) Unplug ECG cable and respiration test is complete. 5. Temperature Test (1) Set simulator temperature output to be 37 degrees Centigrade.

GOLDWAY INC.
UT4000F Pro Service Manual
(2) Connect one end of the BP cable to the BP1 socket on the simulator, the other end to the IBP1 socket on the monitor. (3) Press Zero in the IBP menu. (4) Select ART to be the blood pressure measurement position. Observe if the IBP parameter area displays blood pressure reading on the screen and if the waveform channel has IBP waveform (IBP channel shall be set in the menu in advance). (5) Change the BP output in the simulator to be 200mmHg. (6) Observe if the parameter display area on the screen displays 200 or 200 ±6mmHg.

(5) Power off the simulator and unplug the oximetry cable. Pulse oximetry test is complete. 8. Non-invasive Blood Pressure Test and Calibration The accuracy of the NIBP reading of the monitor is decided by: NIBP calibration and the measurement range of the blood pressure sensor. Correct testing and calibration methods are as follows: (1) Unplug all cables connected to the monitor except for the power cable. (2) Turn on the power switch of the monitor. (3) Connect the hose of the cuff to digital pressure meter, auto inflating bladder and NIBP socket at the side panel of the monitor through a 3-way TEE. Inflate the cuff to a certain pressure level, compare the pressure reading on the digital pressure meter and the monitor screen to see if their value difference are less than 3 mmHg. If not, you need to do blood pressure calibration. (4) Input a password and enter the system maintain menu as follows,
(5) Rotate knob to Pressure Compensation, select the value to be calibrated (-6 – 6mmHg or Auto), then exit the system calibration menu. (6) Repeat (3) , if digital pressure meter and monitor screen have the same pressure value, then calibration is complete. If not, re-calibration is required. If the same results cannot be obtained 3-4

Section 4 Troubleshooting A. Special Components 1、 Surface Mounted Devices Surface mounted devices are used to aid in miniaturizing the electrical assemblies within the monitor. Warning：Surface mounted components were not designed to be removed or replaced using standard soldering equipment. Removal of surface mounted components using a conventional soldering iron can potentially destroy the PCB. Only soldering workstations specifically designed for surface mount technology may be used to remove and replace these type of components.
B. Power Failure 1 No display after power on Phenomenon:
When the monitor is powered up, there is no display on the screen and LED does not light up.
Inspection method:
1) Without connecting the monitor to AC power supply, check the
battery power level.
2) When connecting the monitor to AC power supply, check the
connection between the power socket and the plug of the monitor, the power cable, and the AC output.
Solution:
Make sure all connections are reliable and connect the monitor to AC power supply to charge the internal battery.
C. Data Received Trouble 1 No ECG waveform Phenomenon:
When leadwires are connected, there is no ECG waveform. The screen displays “LEAD OFF” or “NO SIGNAL”.
Inspection method:
Check ECG electrodes contact with patient’s skin and check all leadwire connections. 4-1
GOLDWAY INC.
Solution:
UT4000F Pro Service Manual
Replace ECG electrodes and clean the skin surface where electrodes are applied. 2) Resistance of 1kΩ should exist between extension wires applied to patient body to the leads of the ECG connector. If it is indefinitely large, it shows that the leadwire is broken and should be replaced. 3) If ECG waveform channel shows “No signal received”, then it shows there is some problem in the communication between ECG module and the main system. If this message still remains after the monitor is turned off and on again, please contact the supplier. 1)
2 ECG Baseline Shift Phenomenon:
ECG baseline is not stable, occasionally shifts out of the display area.
Inspection method:
1)
Solution:
1)
Check if the working environment is very humid and if the monitor has moisture inside. 2) Check if the electrode’s quality is good, and the skin surface where the electrode is applied is clean. Turn on the monitor and let it run for 24 hours to remove moisture inside. 2) Replace it with good electrode, clean the skin surface where the electrode is applied.
3 ECG Waveform Noise Phenomenon:
ECG waveform is too large, no entire frame of ECG waveform can be seen.
Inspection method:
Check if the ECG scale is so high that it results in the ECG waveform overflow.
Solution:
Adjust ECG scale to a proper level, normally 1.0mV or 2.0mV.
4 Electrosurgical interference on ECG Phenomenon:
In the surgical operation procedure, the use of electrosurgerical equipment will cause interference on ECG.
Inspection method:
Check the grounding condition of the monitor and the electrosurgical equipment.
Solution:
Make sure the monitor and the electrosurgical equipment are properly grounded. 4-2

UT4000F Pro Service Manual
Weak Respiration Signal
Phenomenon:
The respiration waveform is too low to examine.
Inspection method:
Check if the ECG electrodes are located correctly and if the ECG electrodes contact with patient’s skin is well.
Solution:
1)Apply the ECG electrodes as Fig. 4-2 in P4-5 show, clean the skin surface where electrode is applied. 2)Select other lead.
6 No SpO2 reading Phenomenon:
In the process of monitoring, there is no SpO2 waveform and data.
Inspection method:
Check the finger probe to see if there is red light, if the arm is being pressed, and if the room temperature is too low.
Solution:
If there is no red light in the finger probe, check the extension cable and connecting part. When room temperature is very low, do not expose patient’s arm outside , which will affect the measurement results. Do not measure blood pressure and SpO2 on the same arm. Pressing the arm will affect SpO2 measurement. If SpO2 waveform channel shows “No signal received”, it indicates that there is a problem in the communication between SpO2 module and the main system. If, after turning the monitor off and on again, the message still remains, change the SpO2 board.
7 Intermittent SpO2 Signal Phenomenon:
During SpO2 measurement, the reading is off and on.
Inspection method:
1) During prolonged monitoring and surgery, check if patient arm movement results in interruption of SpO2 measurement. 2) Check the SpO2 extension cable.
Solution:
Keep the patient steady. It is normal if SpO2 value is lost due to hand movement. If SpO2 extension cable is faulty, replace it.
8
Abnormal NIBP reading
Phenomenon:
NIBP measurement result is abnormal.
Inspection method:
Check if the cuff leaks or the tube connector leaks.
Solution:
Replace it with good cuff and connector. 4-3
GOLDWAY INC.
UT4000F Pro Service Manual
9 Low Inflation Pressure Phenomenon:
During blood pressure measurement, the inflation pressure keeps to be low.
Inspection method:
Check if the NIBP cuff or extension tube is broken.
Solution:
Replace it with good NIBP cuff and extension tube.
10
Abnormal IBP Values
Phenomenon:
Displayed IBP values are different than expected.
Inspection method:
Check tubing for bubbles.
Solution:
Rezero the transducer.
11 Wrong displaying of IBP waveform Phenomenon:
Displayed IBP waveform is not regular.
Inspection method:
Check if the cable is outburst.
Solution:
Replace good quality cable.
