3 Information on verification of the scale

The following document content provides some background on the Babyleo TN500 scale. The document is intended for submission to calibration agencies and officials, other official bodies, or persons as appropriate.

3.1 General information

The Babyleo TN500 is a heat therapy device for premature babies and neonates. It can be used to warm patients with a body weight of up to 5 kg (11 lbs) and height of up to 55 cm (22 in). The Babyleo TN500 provides a controlled environment with heat and humidity. The device can be used as an incubator and as a radiant warmer.

A non-automatic scale can be integrated into the device as an option for determining the patient’s weight.

The device’s scale is approved in accordance with the requirements of the regulations of EU Directive 2014/31/EU for non-automatic weighing instruments. The certificate number is T11461. The notified body is the National Metrology Institute (NMI) in the Netherlands.

The scale has the following features:

Drägerwerk AG & Co. KGaA (Lübeck, Germany) evaluates the conformity of the scale. Pursuant to standard EN 45501:2015, the scale consists of the two weighing module and terminal components.

Weighing module: Located directly under the mattress tray. When weighing, only the patient with all the objects (incl. mattress) on the mattress tray are weighed. The weighing module can be removed from the device for cleaning.

Fig. 1 Weighing module

Terminal: Is the remaining part of the device pursuant to EN 45501:2015.

Both components are connected by a disconnectable connector and a cable.

Two labels are provided for assigning the terminal and the weighing module:

– Label on the weighing module: Contains the serial number of the weighing module (see Fig. 3 in chapter 3.5.2 Labeling the weighing module).

– Label on the terminal: Identification of the assigned weighing module via the corresponding serial number (see Fig. 2/1 in chapter 3.5.1 Device labeling).

3.2 Scale function

The weighing process starts after pressing the key and lifting the baby. Weighing is completed when the baby is placed on the mattress tray.

The device does not display any current weights, only the result of the last "Weigh" or "Reweigh" weighing process.

Maximum load

No values are displayed if the weight exceeds the weighing range, and the following message is shown: Maximum weight exceeded.

Maximum tare weight

The following message appears if the maximum tare weight is exceeded: Load is too high for zeroing.

40

80

3.3 Geographic position

The location data of the place of application (latitude and altitude, geolocation data of the scale) is saved on the terminal and secured against accidental changes by a non-resettable change counter. The location data of the operating location and the associated change counter can be read off the scale label on the rear of the device (see Fig. 2/1 in chapter 3.5.1 Device labeling).

In addition, the location data of the operating location stored in the device can be read out via the service menu (see Fig. 13/3 and chapter 3.11 Access to the service menu).

When calibrating the weighing module, the location data of the calibration location (cannot be read out) is read out for the currently set place of application and saved in the weighing module together with the calibration curve. Every calibration process is secured against unauthorized changes by a non-resettable change counter (calibration counter). The counter reading of the change counter is noted on the label on the weighing module together with the calibration date. The calibration counter can also be read out in the service menu (see Fig. 13/2 in chapter 3.11 Access to the service menu).

Before starting the weighing process, the geolocation data is transmitted from the terminal to the weighing module using a secured data path. The weighing modules uses the transmitted geolocation data and the stored location data of the calibration location to perform a geocorrection. The corrected weight value in grams is transmitted to the terminal via the secured data path and Weight (full resolution) [g] and Weight [g] are displayed in the service menu. The weight value Weight [g] is displayed in accordance with the scale’s metrological specification in clinical operation.

3.4 Software identification

To completely identify the software, the software version of the weighing module must be considered together with the product software version.

The software version of the weighing module can be read off the label on the weighing module (see the Fig. 3 circled in green in chapter 3.5.2 Labeling the weighing module). The product software version can be read off the scale label on the rear of the device (see Fig. 2/1 in chapter 3.5.1 Device labeling).

The software versions can also be read out in the service menu (see Fig. 12/1 and Fig. 13/1 in chapter 3.11 Access to the service menu).

3.5 Labeling

3.5.1 Device labeling

The scale label (2M60669, Fig. 2/1) with information on the scale and the device’s name plate (Fig. 2/2) are located on the rear of the device.



Fig. 2 Device labeling

3.5.2 Labeling the weighing module

The weighing module’s name plate (2M60657) is located on the base of the module. SN stands for serial number.

The label with the calibration data, the software version, and the scale identification (2M60660), and the label with the approval number (2M60659) are located on the right side of the weighing module.

3.5.3 Alternative labels

The factory labeling may need to be replaced as part of a repair or software update. The contents of the alternative labels are identical to the factory labeling, but the product-specific fields are not filled. These fields are filled out on site as part of the repair.

A corresponding comparison can be found in the following table.

3.5.4 Recommendation for affixing calibration marks and security marks

We recommend affixing the calibration mark near the label with the approval number. The scale label on the rear of the device (2M60669, Fig. 2/1) and the label with the calibration data (2M60660, Fig. 3) contain variable data. This data is initially printed on the label by the manufacturer as part of the assessment of conformity. In the event of subsequent changes, e.g. calibrations, the data is hand-written on a new label with empty fields. We recommend protecting these labels against unauthorized changes by using security marks during the calibration.

3.6 Turning the device on and off

3.6.1 Turning the device on

Procedure:

1. Connect the power plug.

2. Turn on the main switch on the rear of the main column (I position).

3. Then turn the device on at the front on the control unit with the Start/Stand-by button (Fig. 5/1).

The device performs an automatic self-test. The main page is then displayed.

NOTE

Before removing the power plug, the device must also be turned off at the main switch. If the device is only turned off with the Start/Stand-by button on the control unit, and the power plug is subsequently disconnected, an alarm signal sounds for a few minutes.



3.7 Important instructions for handling

These instructions must be followed to ensure correct weighing:

– The device with the scale has been acclimatized in the test room for at least 24 hours.

– The device is in operation and the scale connected.

– Before the start of calibration, the device must have been in operation for at least 10 minutes to allow the operating temperatures of the load cells and the electronics to stabilize.

– For optimal access, operate the device in radiant warmer mode (with hood open) and move the mattress tray to the top position (see Fig. 11).

– The radiant warmer is switched off.

– The side access panels are folded down.

– The device is not located within a draft (e.g., from air conditioning).

– The trolley brakes are engaged.

– The air bubble on the spirit level is within the black ring and does not touch the ring.

– Attachments, such as supply and discharge hoses, have been removed.

– Make sure that exact weighing is not impaired by wind or drafts.

– When the device is raised, do not touch the mattress tray and the device.

– So as not to distort the weighing result, do not use the mattress tray as support or, for example, touch the mattress tray with scrubs.

– We recommend placing a setting load of 10 kg onto the mattress tray for approx. 10 s three times in succession before calibration.



3.7.1 Switching to radiant warmer mode and turning off the radiant warmer

1. Open the hood.

The device automatically switches to radiant warmer mode.
