If or when are conditions of operation of equipment (in this case enforcement cameras) outwith the Home Office Approval of operation ... ?
If the claims of the unit being outside the bounds of rated temperature are true, would that invalidate Home Office Approval?
Any manual that recommends a specification of operation surely must be heeded beyond the Home Official Approval. Surely all parameters have been physically checked and assured, or is it just a rubber stamping exercise ?
What do they test and and where ?

ooops! there you go with your assumptions again. the speedmeter handbook doesn't set conditions of type approval, only requirements to gain type approval. Conditions are something quite different and this is not a condition.

A distinction without a difference?

Let's try it your way:
Ernest Marsh could have wrote:
It is requirement to gain type approval that it shuts down when the temperature is too low:

Are you happy now GS? :roll:

As I understand it, if a device were submitted for type approval, and it had no temperature sensor which prevented it's operation outside of the prescribed range, that type approval would then not be given.
So type approval is given on the condition that the sensor is present in the device during assessment by the HO (and in use).
The speedmeter handbook uses the term "requirements" Once in use, the condition is established that there MUST be a sensor - it is not just there during assessment by the HOSDB.

I'm surprised that such consideration is being given to terminology and grammar by somebody who on occasions has difficulty in writing basic sentences without errors! :roll:

I find it amazing what a course at Sheffield HU can achieve given the quality of some students they have to work with... surely a success story for the previous government?

Thhe speed is correct. on studying the data block the camera is set on a 0.5 seconds between photos. the top left of data block, first letter is an ' A' which signafies that the vehicle is travelleng AWAY from the camera. The dash under the A confirms that the Radar unit is set on the first power setting, ( 2 Power settings can be used. The second power setting would give greater range at an angle of 20% and allow for readings on oncoming vehicles..The unit would have to be set for this and would have to be manned as only one picture is taken from that forward direction and in addition the letter 'A' would be replaced by the letter 'F for Forward'. :880:
