To use this function, the suction level must be set to at least level 3 in custo diagnostic. With automatic suction power control, the suction level is increased until the system is airtight and the electrodes rest tightly enough against the skin of the patient. If the suction level is set manually, automatic suction level control is deactivated.
1) The power supply for the custo cardio 400 is 12 Volt DC instead of 15 Volt DC from the custo cardio 200. The connection is the same what happens if they are swapped?
The maximum input voltage for the custo cardio 400 is 15 Volt DC. So the power supply from the custo cardio 200 can also be used. The power supply for the custo cardio 400 however is a medical power supply.
2) Can the cardio 400 be used with a custo power station and a Onyx Venus Tablet?
The custo cardio 400 will work on both devices. The Onyx Venus has to be used in 12 Volt DC output mode.
3) Can the custo cardio 400 also be powered by a USB port?
No, it is not possible to power the custo cardio 400 by USB ( this was also NOT possible for the custo cardio 200).
4) What is the minimum required software under which the custo cardio 400 will run?
custo diagnostic 4.6 and custo diagnostic 5.0. (this however also applies to the custo cardio 300)
5) What is Automatic suction level control?
To use this function, the suction level must be set to at least level 3 in custo diagnostic. With automatic suction power control, the suction level is increased until the system is airtight and the electrodes rest tightly enough against the skin of the patient.
If the suction level is set manually, automatic suction level control is deactivated. Under level "3" the automatic suction control is not activated. ( It can be deactivated by pressing the "+" and "-" button on the cardio 400 simultaneously)
6) What suction levels can be set over custo diagnostic and what levels manually?
custo diagnostic can set 6 suction levels, from level 0 up till level 6 ( from 0 up till minus 280 mbar)
In manual mode you cannot set a lower value than step one ( -60 mbar) this to prevent that the user accidentally switches off the device and have all the electrodes drop off.
7) What do the different colors mean in the suction visualisation on the cardio 400?
Blue: the device id connected using a wireless connection ( Bluetooth or WiFi)
turquoise: The device is connected using USB (USB-Modus)
Yellow:
- The moisture sensor is has detected moist in the tubing of cardio 400 Es the device still continues working normally.
- The cardio 400 has detected a leak for over 5 minutes the under pressure cannot hold the set suction level. The automatic suction control is disabled and the LED for the lowest suction level lights up. ( an error has been written in the error.log file)
- The system has a to high under pressure (<= -300mbar) The automatic suction control is disabled and the LED for the lowest suction level lights up. ( an error has been written in the error.log file)
Green: The automatic electrode dropoff is activated or the cardio 400 has been set into cleaning mode (<= 1min). The indication for the suction level has been used as countdown timer.
Orange: A key combination has been pressed e.g. to reset the cardio 400.
8) What should be done in case of a WARNING (e.g suction level to high or leak in the cardio 400)?
The cardio 400 can, in case of a warning, normally be used.
9) Key combination on the cardio 400.
Press the ON- key for >= 3 Sec.
Pressure LED will light up Orange.
Depending on the settings in custo diagnostic will either the cardio 400 activate the 10 seconds automatic resting ECG record or the ECG will be started and can be finished by pressing the ON key for another 3 seconds or stopping the record in custo diagnostic.
It is possible to configure custo diagnostic that it records 10 seconds of ECG (Setting : Autostart ) using start will record ECG till the next time the start button on the cardio 400 is pressed again. Or you can always stop the ECG in the custo diagnostic program.
- Press >= 3 second on the cleaning button ist not functional jet.
- When the plus and minus key on the cardio 400 are pressed simultaniously for >=3 seconds you will activate a hard reset. This cannot be activated during a record of an ECG.
10) How to update the firmware of the cardio 400
You can update the firmware of the EAS01 circuit board by using the firmware update tool. This circuit board is responsible for the ECG amplifier. Inside the cardio 400 there is a second circuit board, the EAS02 the control board, this can only be updated in the factory.
