“Err8” is displayed on the measuring instrument (when the upgrade of the wireless adapter Z3210 fails).


This page explains what to do when “Err8” is displayed on the display of a measuring instrument in which the wireless adapter Z3210 is inserted.

This issue is caused by the failure of the upgrade of the wireless adapter Z3210 to operate properly.
Please follow the steps below to re-write the firmware and recover.

1. Plug the wireless adapter you want to restore into the measuring instrument. Turn off the power of the instrument.
2. Tap “Other” in the bottom menu.
3. Tap “Z3210 Recovery”.
4. Turn on the measuring instrument. Then, GENNECT Cross will display the wireless adapter’s unique ID. (the format is XX:XX:XX:XX:XX:XX for Android, and XXXXXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX for iOS. In both cases, the “X” is alphanumeric)

5. After “Err8” appears on the instrument’s display, tap the “UPDATE” icon on the GENNECT Cross.
※If you start writing before the display changes to “Err8”, writing will not be performed normally.

6. Select “OK” in the confirmation dialog to start the firmware re-write.
