Has anyone ever got a error message 'hot' on their megger whilst doing a rcd or a non trip loop test?

Straight from the megger manual.
To protect the MFT from overheating during Loop testing, thermal protection is fitted. If the message ‘HOT’ appears in the display when loop testing, the instrument must be allowed to cool down before further attempts are made at loop testing.
The RCD circuit has thermal protection fitted to prevent overheating in the event of multiple ramp tests being performed. The T symbol or the message "Hot" will be displayed. Allow the instrument time to cool down before continuing.
