Dash 2500 GE Patient Monitor Nellcorrr Spo2 Board 10006861

GE DASH2500 is a subcritical monitor recently launched in 2006, suitable for adult, newborn and operating room vital signs monitoring. The Dash2500 adopts a fully modular interior design concept for easy maintenance and upgrade. It is the first time that the product adopts aerospace plastic shell on the monitor, which has unprecedented anti-seismic and anti-fall performance. In addition, the instrument has passed strict high temperature resistance, high humidity, waterproof and six-side drop test to ensure that the instrument can be used normally in a variety of harsh environment.

The GE Dash2500 monitor consists of a host, battery, accessories, and power cable. Accessories include ECG lead (without electrode patch),

NIBP noninvasive blood pressure cuff and hoses, Temp temperature sensor and Sp02 blood oxygen saturation sensor, 1 2500 1 color display monitor, the Dash three-channel wave 1 1 operation interface in Chinese baby, adult and children's heart I ert the cable 1 five pattern 1 standards, Button type 1 adult reusable non-invasive blood pressure kit 1 Pulse oxygen saturation cable 1 adult reusable oxygen finger clip 1 power cord, Australian plug 1 thermal printer 1 Operating manual 1 Rechargeable lithium battery (one piece) 120 minutes

GE DASH1800/DASH2500 Monitor blood pressure failure maintenance

Fault Philipilipenomenon: blood pressure pump inflated to about 100 pressure is not rising.

Fault diagnosis: The blood pressure module is faulty

Breakdown maintenance: as follows

1. Check the air pump and pipelines and find no air leakage.

2. Blood pressure pump was tested and found to be normal.

3. Press the pump button to vaguely feel air leakage, because there is no air leakage valve and pipeline, so check the vent valve, found that the vent valve leakage.

4. Replace two air relief valves of the same model and the fault is removed.

Maintenance of GE DASH1800/DASH2500 ECG monitor faults

Fault symptom: Press the pump button does not start.

Fault diagnosis: button problems or blood pressure board problems

Breakdown maintenance: as follows

1. Check the key and find that there is no problem with the key.

2. Press the pump button to measure the voltage of the pump and find that there is no voltage.

3. Using a multimeter to test the blood pressure board, it is found that there is only input voltage but no output voltage in a stable voltage block. So there's a problem with that.

4. Replace it with a new one of the same model.

The GE DASH1800/DASH2500 monitor is faulty

Symptom: After starting the device, the battery is low and needs to be charged

Fault diagnosis: Battery damage or mainboard failure

Breakdown maintenance: as follows

1. After replacing a battery, the fault persists.

2. Since the charging circuit of the battery is on the mainboard, the charging circuit on the mainboard was detected, and a resistor next to the voltage comparator was found to be burnt out. As the comparator was also aging, the resistance and voltage comparator of the same model were replaced, and the fault disappeared.

GE DASH1800/DASH2500 ECG monitor displays faulty maintenance

Symptom: Two lines of parameters are displayed on the screen after startup

Fault analysis: because the parameters are normal, so eliminate the motherboard failure.

Fault diagnosis: wiring fault or display fault

Breakdown maintenance: as follows

1. Use a multimeter to check the cable connecting the monitor to the mainboard. The test results are normal. Therefore, the platoon fault is eliminated.

2. If all display parameters are normal when an external monitor is connected, the monitor is faulty.

3. Maintain the display driver and restore everything to normal.

GE DASH2500/DASH1800 Monitor blood pressure failure maintenance

Fault symptom: Blood pressure cannot be detected

Fault diagnosis: The blood pressure board may be faulty

Breakdown maintenance: as follows

1. If the device self-test succeeds, the mainboard is in good condition.

2. Blood pressure pump, air valve and sensor are normal.

3. Enter the menu of blood pressure calibration and press start to keep the working pressure of air pump at 240. Press stop button solenoid valve to work. All the instructions are ok, then the fault should appear in the DAS board.

4. The pressure sensor was found damaged by DAS board inspection, and everything returned to normal after replacing with a new pressure sensor
