There are two versions of the BPK-Probe, the older version, V1, and the new version, V2.  The V2 probe was developed with new and upgraded features including the ability to connect to Helwig’s newest product, the BPK-Probe DataLink app.  The two versions are easily distinguished by the display screen. The main differences are the color of the display and the status icons. Also, only the V2 versions are eligible for a firmware upgrade to enable the probe to link to the DataLink App.  Follow the simple steps below to be able to tell the version of your probe and if a firmware upgrade is already installed or has the ability to be installed.

Version 1 has a monochrome (non-color) display and is not eligible for the firmware update.  Therefore, it is not able to connect to the DataLink app.

Version 2 has a color display with added features and status icons.

  • If you see the 2-digit alphanumeric code in the upper right corner, your probe is upgraded with the latest firmware and able to connect to the DataLink app.
  • If you see a color display but no 2-digit number, the probe still needs the firmware upgrade to be able to connect to the DataLink app.

There are two reasons why the DataLink app will not automatically sync with your phone.

  1.  The BPK-Probe may need an upgrade.
    • Please see FAQ “Does my BPK-Probe need an upgrade to connect to BPK-Probe DataLink App?
  2. If you are an Android user with version 12, you may need to update some phone settings.
    • Please see FAQ “Which platforms are compatible with the app?
    • Or click here for instructions to sync your version 12 Android.

Yes, all test data is stored on the BPK-Probe’s Micro SD card. Please see the BPK-Probe Operating Instructions to retrieve test data from the SD card.

Test data is exported in a Report Format as a PDF. Altering test data is not possible.

You will not be able to test if the link is broken. Reestablish the link by ‘waking up’ the BPK-Probe then using the app to reconnect. Click Here for details.

Yes. It can only be accessed by the registered user of the app.

IOS version 14.1 and Android, version 8.0.0 or later. The app is not compatible with other platforms like Microsoft Surface Pro, etc… or units w/o BLE communication.

Android version 12 may need some permissions edited before phone will sync with the DataLink App.

Yes. At your request, we’ll send you a shipping label. Send Probe ONLY. Typically updates are done on the same day.

All saved data is maintained in a secure location on the Cloud. To recover data, please contact Helwig Carbon.

Yes, when you tap SEND from the Export screen, your default email client will open where additional recipients can be added, Subject line changed, text added, etc.

Yes, in your default email client, the report is an attachment. On iOS, it can be viewed by selecting the displayed image. For Android, select the attached PDF icon.

No. The Data Link is designed as an accessory to the BPK-Probe.

No – you must use the green grounding cable for every test, every time, even if the “ground” switch on the probe is disabled. It needs to have a ground reference to work properly every time.

Why We Test For Shaft Voltage (And You Should, Too!)

Bearing discharges damage the motor bearings in two ways: the degradation of the bearing grease the roller assemblies are suspended in, and by electrostatic machining (ESD) of the bearings and bearing raceways. The combination of the two can be devastating to the life of the motor bearing and should be mitigated to avoid costly repairs and machine downtime.
