Battery performance

About the batteries

The device uses a rechargeable, 2-cell, Lithium-ion smart battery. Internal circuitry enables the battery to report its condition to the device. The device displays the battery status via the LED power indicator, icons on the screen, and status messages appearing in the Device Status area of the display.

The battery status indicator on the device displays the remaining charge. Battery information may be collected using the service tool.

New batteries are shipped from the manufacturer with a 30 percent charge to extend shelf life.

After installing a new battery in the device, you must plug the device into AC power to wake up the battery. If AC power is not applied to the device, the new battery appears discharged.

The Device Status area displays a low-battery notification when 30 minutes of power remain and again when 5 minutes of power remain. The 30-minute notification is dismissable by the user, and all functions of the device remain available. The 5-minute notification is not dismissable, and prevents acquiring vitals measurements or performing any other function until the device is plugged in to AC power.

If AC power is not applied to the device after it triggers the 5-minute notification, the device will shut down at or close to 0 minutes of remaining battery charge.

Battery charging is provided by the device’s internal power supply. The power reserve threshold is determined by the device's software.

For a complete list of battery specifications, see the device’s

Instructions for use

.

If all tests are successful, the system completes power up, the Home tab appears, and the system is ready for operation.

If the self-check fails, an error message and an error code appear in the system status area at the top of the screen to aid service personnel and engineers in diagnosing the problem. If a fault that could adversely affect the product is detected, the system enters a safe mode and stops all vitals functions. The system remains in safe mode until it is turned off by pressing or until the device shuts down automatically after a period of inactivity.

To perform the POST:

1. Disconnect any patient cables connected to the system.

2. Insert a fully charged battery into the system.

3. Power up the device and confirm the following: a. The buzzer generates a sound.

b. A startup screen appears briefly and then disappears.

c. The power button flashes until the UI is ready.

Functional verification and calibration overview

Functional verification tests

The functional verification tests help to confirm the proper operation of the device and its options.

The tests may also be useful as a diagnostic tool to help isolate a malfunction. It is not necessary to disassemble the device to perform these tests.

For periodic service, you can—at a minimum—perform the basic functional verification tests described in this manual. If you have the Gold edition of the service tool, you have the additional capabillity to perform a complete functional verification and calibration of the device, but this is not required for minimal periodic service.

In contrast, any time you open the device case, you must use the service tool, Gold edition, to perform a complete functional verification and calibration of the device before returning the device to service.

NOTE

For instructions on using the Gold edition, see the service tool help files.

About the Welch Allyn Service Tool

The service tool is required to complete functional verification and calibration tests. The service tool is available in the following editions:

Standard unlicensed edition

: Enables NIBP functional verification tests to satisfy the recommended annual service. If any Standard unlicensed edition testing shows an out-ofspecification result, use the Gold edition to perform a full calibration.

Gold edition

: Checks the functionality and calibration of the device. As it checks the device, the Gold edition also performs any needed calibration to bring the device within specifications. This full suite of tests is required to complete a repair. Each time you open the case, you must use the Gold edition to test the device before returning the device to normal use.

For information about the service tool, see the following:

• For instructions on installing and using the service tool, see the

Welch Allyn Service Tool

Installation and Configuration Guide.

• To use the Standard unlicensed edition to test the NIBP module, follow the instructions in this service manual.

• For instructions on using the Gold edition, see the service tool help files.

Electrical safety testing

Welch Allyn recommends performing ground continuity and leakage current tests after all opencase repairs and dielectric strength testing is not recommended.

NOTE

Perform dielectric strength testing only if there is a reason to doubt the integrity of the electrical insulation (e.g. multiple trips of a residual-current device or liquid ingress of a saline solution). If you determine this test should be performed, return the device to Welch Allyn for service.

These recommendations trace to EN/IEC 60601-1 – Medical Electrical Equipment – Part 1: General

Requirements for Basic Safety and Essential Performance or EN/IEC 62353 – Medical Electrical

Equipment – Recurrent Test and Test After Repair of Medical Electrical Equipment.

Because of the variability of test equipment in the field, Welch Allyn does not include specific instructions to perform electrical safety tests. When performing electrical safety tests, refer to your test equipment manuals for detailed instructions to ensure proper test equipment setup that aligns with the appropriate standard. The following table provides connections and test limits to assist you in performing these tests.

70 Functional verification and calibration overview

Test Limits

Ground continuity (see Note above) Ground continuity from EP stud (equipotential terminal)* to the Gnd pin of the IEC power connector shall be no greater than 0.1 ohms.

Leakage current (see Note above) Leakage current shall be less than 500 µA from EP stud* to mains (Line and Neutral pins of the IEC power connector).

Insulation resistance Dielectric strength shall be 500 V (DC) EP stud* to IEC mains (Line and

Neutral pins of the IEC power connector), and insulation resistance is measured.

* To locate the equipotential terminal, see “Controls, indicators, and connectors."

Devices with an External Power Supply

The power bricks are CB Certified and UL Listed; they meet ALL of the requirements that the

Medical Device standard requires for power supplies. The manufacturer is required to perform

100% electrical safety testing on all of their power bricks prior to shipment. Welch Allyn does not perform nor recommend testing on these external power bricks because additional testing would put undue stress on the insulation system and possibly cause premature failures in the field. Open case repairs of devices with external power supplies are only dealing with DC circuitry and robust isolation circuits built into the printed circuit boards. No additional after-servicing testing is required in that instance. The patient isolation systems within the device (Temperature Probe,

SpO2 sensor, etc.) all have visible isolation gaps built into the printed circuit board. The quality control on the PCB and the thorough type-testing performed by the testing agency (ETL) eliminates the need for further testing on the devices that are downstream from the mains isolation device.

Devices with an Internal Power Supply

The internal power supplies are CB Certified and UL Registered. These power supplies are an open frame style (no protective enclosure). Therefore, the products that contain an internal power supply require electrical safety testing. Open case repairs of devices with an internal power supply require the recommended testing because those devices contain the open frame power supply, and the testing involves the manipulation of wiring that carries 120 or 240 volts AC. Welch Allyn does not recommend HiPot / Dielectric Withstand testing because of a potential stress on the insulation system, which could cause premature failures.

Basic functional verification

Basic functional verification checks

NOTE

Calibration is available only with the service tool, Gold edition.

These tests verify basic functionality of the NIBP, SpO2, and thermometry parameters. These tests support the requirements of routine preventive maintenance. However, they are not a substitute for the complete functional tests available with the service tool, Gold edition. Welch Allyn recommends using the service tool, Gold edition, to perform preventive maintenance and verification of the device when completing a repair.

NIBP accuracy check (Standard unlicensed edition)

The NIBP accuracy check is performed manually using the service tool to control the valves. The accuracy check compares the reading from the primary transducer pressure shown in the service tool window with the reading from an external calibrated digital pressure meter. The results of this check are not recorded in the service tool log file. To record the results for your records, copy the table in the service record section of the service manual. If a calibration is required, run the NIBP calibration included with the Gold edition of the service tool.

WARNING

Patient safety risk. If the primary transducer fails, the system might not identify an overpressure condition at the right limit, causing injury when the device is re-connected to a patient. To ensure patient safety, Welch Allyn recommends that a qualified service technician perform a full functional verification and calibration on an annual basis.

74 Functional verification and calibration overview

CAUTION

Equipment calibration error can occur. This accuracy check verifies only the accuracy of the primary transducer. If the safety transducer is out of calibration, a calibration error can occur due to the pressure difference between the primary transducer and the safety transducer. To avoid equipment calibration errors, Welch

Allyn recommends that a qualified service technician perform a full functional verification and calibration on an annual basis.

Tester, calibration, 9600 Plus

Cal-key, assembly, M690/692

SureTemp temperature system test

The SureTemp temperature system test is performed using a calibration key (cal-key). The calibration key tests the system using a fixed resistance to display a temperature of 97.3 ± 0.2 °F

(36.3 ± 0.1 °C).

NOTE

If your facility requires you to test the temperature probes, you will also need to have heaters at three temperature settings to test the probes. See

"SureTemp temperature probe and system test."

Perform a SureTemp temperature system test

1. With the system power on and the temperature probe in the well, disconnect the probe cable from the temperature input connector on the front of the device.

2. Connect the calibration key to the temperature input connector.

3. Remove the probe from the well.

4. Verify that the displayed temperature is 97.3 ± 0.2 °F (36.3 ±0.1 °C).

SureTemp temperature probe and system test

Use this procedure to test the temperature function while verifying the temperature probe. To achieve accurate results, you must perform this test with the device in Direct mode.

Service manual Functional verification and calibration overview 77

Test each probe at the low, medium, and high set points on the tester. Repeat the procedure for each thermometer and temperature to test.

Set up the 9600 Plus calibration tester

Place the tester on a level surface away from sunlight, drafts, and other sources of heat or cold.

The tester takes approximately 20 minutes to heat to the lowest set point.

To expedite testing, Welch Allyn recommends the following practices:

• To eliminate waiting for the tester to heat to the next set point, use three testers, each set to one of three different set points.

• When using only one tester to test several thermometers at all three temperatures, test all thermometers at one set point before proceeding to the next set point.

• To eliminate waiting for the tester to cool down, start at the lowest set point. Because the tester does not have an internal fan, it requires more time to cool down than to heat up.

Change the 9600 Plus set point

To scroll from one set point to the next, press and hold the Temperature Selection button until a beep sounds.

The new set point appears in the upper left corner of the display. The device’s current temperature appears, flashes, and continues flashing until the cavity reaches equilibrium at the new set point.

The 9600 Plus beeps when the set point is reached.

Perform a SureTemp temperature probe and system test

1. Set the 9600 Plus to the desired set point and wait for the display to stop flashing.

2. Insert the temperature probe, without a probe cover, into the thermistor device port on the tester.

3. When appears on the display, touch it to switch to Direct mode.

4. Wait for up to two minutes for the temperature reading to stabilize.

5. Record the results in the temperature service record.

6. Return the temperature probe to the probe well on the device.

7. Repeat the procedure as necessary until all thermometers are tested at each temperature.

To record the results of your test, go to "Service record."

Options and upgrades

Welch Allyn may support option and software upgrades for Spot Vital Signs 4400 (Spot 4400 ).

Option upgrades for devices still under warranty that require any installation inside the device must be performed by a Welch Allyn service center unless you participate in the Partners in Care Biomed

Partnership Program. If you want to install the options, we recommend you attend either the classroom or online technical training course for the device. The training is required to be eligible to receive the Welch Allyn Service Tool Gold edition. The Gold edition is required to verify that the device is functioning correctly after it has been serviced. Although all of the option upgrades are calibrated and tested before leaving the factory, Welch Allyn recommends performing a complete functional test whenever the device is serviced.

NOTE

For the Welch Allyn Service Tool to support updates and upgrades, adjust your firewall settings to permit access for IP address 169.254.10.10 (the local feed server for the software upgrade process).

Software upgrades, when available, can be purchased or provided at no charge if your device is covered by a Welch Allyn Service Agreement. The upgrades can be installed by either a Welch Allyn service center or by using the service tool, Standard unlicensed or Gold edition.

If you choose to install software upgrades on your own, you will receive the software through the internet. When ordering software, provide the serial number of the device you want to install the software on.

NOTE

The device must be plugged in to AC power and have at least 15 minutes of battery charge remaining to execute software upgrades. You can download software upgrades on battery power, but you cannot implement them without AC power.

Available options

CAUTION

Before installing any option, disconnect the patient from the device and power down the device.

Upgrading software with the Welch Allyn Service Tool

The Spot 4400 and the Welch Allyn Service Tool (WAST) interact through Ethernet over USB technology, enabling the device to function as a USB device with both a network and an IP address.

This connection separates logically into two distinct interfaces: a generic USB serial connection and a Remote Network Driver Interface Specification (RNDIS) network interface, which is a Microsoft

Windows driver. Most interactions between the WAST and the Spot 4400 take place over the generic USB serial connection. In contrast, software upgrades require the RNDIS interface for the device to connect the WAST and download the firmware.

During software upgrade, the Ethernet over USB interface with the WAST is auto-configured with the specifications noted in the table below. When the Spot 4400 reaches out to the WAST for the firmware package, it uses either one of the following TCP ports: 80/443. Be prepared to modify any firewall(s) that prevent incoming connections to allow this traffic. The WAST attempts to configure the Windows firewall by opening this specific port on the RNDIS interface. If administrative controls such as a Group Policy Object (GPO) or third-party software have been implemented to prevent this change, the WAST attempts to diagnose the problem and then inform you of possible remediation steps. Work with your IT staff or Network Administrator as needed to enable this functionality.

At the start of a software upgrade, the Welch Allyn Service Tool creates a local HTTP server and uses the USB connection to transfer necessary file package to the Spot 4400. Once the file package is on the device, it launches the installation of host controller firmware and reboots the device immediately following the installation. When the device auto-reboots, the software upgrade of individual modules and sensors (NIBP, SpO2, and/or Temperature) is complete.

Software rollback capability

The Spot 4400 utilizes a primary and secondary software structure. In the final step of the software upgrade, the device rolls the previous firmware package to a secondary image and identifies the newly installed firmware as its primary image. This structure allows rollback to previous versions as needed. For example, if you performed a software upgrade and then determined that it didn't meet your expectations or conform to your workflow, you can execute a software rollback in seconds and limit device downtime. To roll back your software, follow these steps:

1. Connect the device to your laptop and open the Welch Allyn Service Tool.

2. Click the

Configure

tab.

3. In the Current settings window, click

Change...

.

4. Click the

Device Software Rollback

tab.

5. Click

Rollback

.

6. In the Confirm Device Software Rollback dialog, click

Yes

to confirm.

Service manual Options and upgrades 85

In addition, because the software upgrade is already loaded on your device, you can use the rollback capability at a later time to implement the upgrade and complete the associated setup activities. Follow the same steps presented above to activate the new firmware.

SpO2 specifications

Refer to sensor manufacturer's directions for use for additional information.

WARNING

Functional testers cannot be used to assess the accuracy of a pulse oximeter device.

While functional testers may be useful for verifying that the pulse oximeter sensor, cabling, and device are functional, they are incapable of providing the data required to properly evaluate the accuracy of a system's SpO2 measurements. Fully evaluating the accuracy of the SpO2 measurements requires, at a minimum, accommodating the wavelength characteristics of the sensor and reproducing the complex optical interaction of the sensor and the patient’s tissue.

These capabilities are beyond the scope of known bench-top testers. SpO2 measurement accuracy can only be evaluated in vivo by comparing pulse oximeter readings with SaO2 measurements obtained from simultaneously sampled arterial blood made using a laboratory CO-oximeter.

NOTE

Contact the sensor manufacturer for further SpO2 clinical testing information.

NOTE

Refer to sensor manufacturers' directions for use for further accuracy information.

USB flash drive requirements

The multiple vendor technologies used in the manufacture of USB flash drives make some of them incompatible with this device. Common issues that cause flash drives not to function are NTFS formatting, proprietary drive security, and the need for Windows drivers to run or access them.

The requirements for a USB flash drive to work with this device are the following:

• Linux compatibility

• Up to 32 GB storage

• FAT 32 formatting

• USB 2.0 compliant

Dimensions: Assuming the USB flash drive will be inserted into the device, the length of the stick does not matter. The size of the stick surrounding the USB metal head should be no larger than 9.5

mm x 18.5 mm to fit in the USB port.

Welch Allyn recommends the following USB flash drive for use with the device: Kingston

DataTraveler SE9 32 GB drive, part number DTSE9H/32GBZ.

Factory defaults

NOTE

Factory defaults are the settings in the device when it comes off the manufacturing floor. Customized configuration files modify these defaults based on preferences for specific sites. Restoring default settings on a device returns it to its manufacturing floor defaults, not the custom configuration.

Troubleshooting

This section provides the following tables to help troubleshoot the device.

Interpreting log file output

: The tables and sample calculations in this topic show you how to parse and interpret error log messages.

Symptoms and solutions

: This simple table lists symptoms you might observe, possible causes, and suggested actions that might eliminate the problem.

Information and error messages

: These tables list messages generated by the device software when a problem is detected. The tables explain possible causes and suggest actions that can resolve the problem. Compare to the Symptoms and solutions table, these tables are much more exhaustive.

These tables can help you diagnose and fix a problem. They do not replace basic troubleshooting skills. You must still trace the source of the problem to the board or module level to decide the best course of action. Welch Allyn does not support component-level repair to the board or module. For available replacement parts, see “Field Replaceable Units.”

94 Appendix

WARNING

Do not perform troubleshooting on a device that is emitting smoke or exhibits other signs of excessive overheating. Disconnect the device from AC power and call Welch Allyn Technical Support immediately.

CAUTION

Replace parts, components, or accessories only with parts supplied or approved by Welch Allyn. The use of any other parts can lead to inferior device performance and will void the product warranty.

Interpreting log file output

The device supports saving log files to a USB flash drive. You can then read saved log files on a PC to assist in analysis. This method allows access to the log files without having to connect the device to a PC.

Save log files

Complete the following steps to save a log file to a USB flash drive:

1. Insert a compatible USB flash drive into the USB port of the device.

2. Access Advanced settings.

3. Navigate to

Service

>

Log file

.

4. Touch

Save to USB

. A "Save successful" message appears after a successful save.

5. Remove the USB flash drive from the USB port.

Access log files

Complete the following steps to access and start working with log files saved to a USB flash drive:

1. Insert the USB flash drive into a USB port on your PC.

2. Open the USB flash drive and identify the saved log files. Look for .zip files that resemble this example, with the first set of numbers being a datestamp in the YYYYMMDD format:

logfiles_20150108_193903_179.zip

3. Open the .zip file, and then open the desired messages .zip file. Multiple messages files might be saved on the USB drive, so check the datestamp in the filename to select the desired .zip

file. For example,

messages_2015_01_08.zip

The available log files appear onscreen. The largest file is the latest file of the day. The filenames resemble this example:

messages_2015_01_08_0000000008

4. Right-click on the desired log file, select

Open

, and then select Notepad ++ as the program to open the file.

The log file opens and is ready for analysis.

Log message format

Knowing how to interpret log file output can help you to troubleshoot issues on the device. All log messages follow this format:

<PRI>ISODATE(sp)MSGHDR:(sp)MSG(new-line)

The following table defines each element of the log message.

<PRI> The facility number and the severity number concatenated into an 8-bit value.

Service manual Appendix 95

NOTE

The PRI values and calculations performed with them are useful primarily to Welch Allyn engineers. Most biomeds and service personnel can focus on the other details of log messages to complete their analysis.

ISODATE

MSGHDR

MSG

The date and time at which the message was generated in the ISO 8601 compatible standard timestamp format (yyyy-mm-ddThh:mm:ss.mmm+-ZONE). This is picked up from the device system time.

Message header: The name and the PID of the program or process that sent the log message in PROGRAM[PID]: format. It includes a trailing whitespace.

The text of the log message from the sending program or process. This is a free-format text string, terminating with a new-line character.

A single-space character.

A new-line character.

(sp)

(new-line)

Sample log messages:

<13>2014-09-26T12:18:45.000+00:00 wa_nibpd[1326]: NibpManualBpCancelState-

>Enter

<150>2014-09-08T05:55:00.000+00:00 wa_spo2nonind[1521]: Code 1, SPO2 sensor not connected

As noted above, the calculations performed using PRI values have little significance for most users but are valuable for Welch Allyn engineers. Therefore, the following instructions for calculating facilty and severity numbers target Welch Allyn engineers.

96 Appendix

To obtain the facility number, divide the PRI value by 8 (dropping the fraction from the result). The facility number is one of the following:
