The model referenced here (77DE-06-09) is now no longer manufactured. It has been replaced with 77-DB-06-09.
Spec sheet for old model: https://www.farnell.com/datasheets/1596487.pdf Spec sheet for new model: https://www.farnell.com/datasheets/1772940.pdf
There are differences between the specifications of the two transformers, so I wonder if the calibration figure on the line referenced at the top of this post needs updating?
Thank you
Further investigation has found the following value should be used for the 77-DB-06-09 (UK Plug) : 268.97
