When the HAKKO FR-811 is connected by USB cable to a PC running the HAKKO FR-811 HMI Software, and you attempt to upload a profile from the PC to the HAKKO FR-811, you may receive the following error on the FR-811 display:
This error is caused by a mismatch in the unit of measure for temperature between the FR-811 and the PC software. For example, the FR-811 is set to display temperatures in °C but the software is configured for settings in °F.
To resolve this problem, please make sure the PC software and the HAKKO FR-811 are set to use the same unit of measure for temperature.
