Page 4: Introduction
The MP01000 is not a final medical product and carries no CE mark. The module will not hinder you to confirm with the current relevant standards, but also the part of the sy- stem added by the user has to be designed in a way, so that the complete product can be CE marked, FDA registered, or safety tested in a test lab.
Page 5: Overview
Temperatures are transmitted in 10∙°C, e.g. 388 equals 38.8 °C. Overview The MP01000 contains a five lead ECG, a pulse oximeter, a part for measuring a patient's arterial blood pressure, none-invasively, and a two channel thermometer. The module can work with a five lead ECG cable to show 7 channels of ECG, with a four lead cable showing 6 channels, and with a three lead cable to show one channel of ECG.

Page 9 Also flexible PCBs are a good solution for this adapter. NIBP Cuffs While it is not mandatory to use Medlab cuffs for NIBP measurement, best accuracy is reached when using them, as the module's algorithm is developed for the mechanical dimensions of the bladders in the NIBscan cuffs.

QRS Detection, section 201.12.1.101.15 (various sections) If the MP01000 is set to adult mode, the heart rate meter will not respond to ECG signals having a QRS amplitude of 0,15 mV or less, or R-waves of a duration of 10 ms or less, with an amplitude of 1 mV.
Page 13 With over and undershoot: a) For single (ventricular-only) pacemaker pulses alone, with 0.1 and 2.0 ms pulse-widths and ±2 mV and ± 700 mV pulse-amplitudes, the MP01000 correctly displays a heart rate of zero bpm (Asystole). b) For single (ventricular-only) pacemaker pulses with normally paced QRS-T, with 0.1 and 2.0 ms pulse-widths and ±2 mV and ±...
Page 14: Serial Transmission
Optionally, the board can also communicate with the host over a CAN interface, at 250k, 500k and 1000k bit transmission rate. The MP01000 sends data and receives commands. For both CAN and UART mode, the proto- col is block oriented.

Page 22 Medlab medizinische Diagnosegeräte GmbH MP01000 User Manual NIBP Blocks Measurements of NIBP must be individually started by sending the relevant command to the NIBP board. Alternatively, the board can be set to "cycle" mode. Then, a measurement is auto- matically started after the selected time frame has passed.

This is mainly to avoid unintended reprogramming of the parameters during normal operation. Default button sets the form entries to the delivery values of the MP01000. One must press the program button afterwards to reprogram these settings into the board's EEPROM memory, though.

” “ - Select the COM port the MP01000 is connected to Œ. You should now already see data coming in. - Try sending an ECG command, by either entering one of the commands described on page 27 into field •, or by selecting several of the ECG traces you want to receive in the tick boxes Ž.
Page 35: Regulatory Considerations
Therefore, the MP01000 has not been - and also cannot be - CE-marked. The customer has to undertake the procedure of CE-marking with the final product that contains the module.
