Who can help to translate the following requirements which is from AMS 2750E?

Thanks very much.

3.5.18 Relocation of Hot or Cold Recording Sensors for Class A or C Instrumentation
When the hottest and coldest temperature locations change within the furnace (based on the final readings from the most
recent Temperature Uniformity Survey), the recording sensor locations for types A and C instrumentation may need to be
moved within the furnace to reflect the new hottest and coldest locations within the work zone. These sensors do not
require relocation if the overall temperature uniformity does not exceed one half of the maximum temperature uniformity
tolerance for the applicable furnace class at all temperatures surveyed, or if the difference between the measured
temperature at the current recording locations and the actual respective hottest and coldest measured areas is less than
the system accuracy test (SAT) tolerance for the applicable furnace class.

Dear Nbxbmy, Thanks very much!

Now we have the new version for AMS 2750 which is F.

It discribed much more clear for this reuqirements.

3.5.15 Relocation of Hot or Cold Recording Sensors for Type A and C Instrumentation
3.5.15.1 When the hot and cold temperature locations change within the furnace based on the readings from the most
recent TUS, the hot and cold recording sensors may need to be relocated to reflect the new hot and cold locations
within each qualified work zone.
3.5.15.2 The hot and cold recording sensors do not require relocation if either of the following conditions is met:
3.5.15.2.1 The temperature uniformity results do not exceed one half of the maximum temperature uniformity tolerance
for the applicable furnace class at all temperatures surveyed. The intent of this requirement is that the TUS
results do not exceed 1/2 of the uniformity tolerance in either direction from the set point temperature.
3.5.15.2.2 The difference between the measured temperature at the current hot and cold recording sensor locations and
the actual respective hottest and coldest measured locations is less than the maximum SAT difference for the
applicable furnace class (see Tables 14 and 15). The intent of this requirement is that the maximum and
minimum TUS sensor readings during the 30 minute TUS soak, recorded and corrected by the TUS recorder,
are compared to the furnace recording of the current hot and cold recording sensors at the same time, and
must not exceed the applicable SAT tolerance.
3.5.15.3 If the qualified operating temperature range exceeds 300 °F or 165 °C and the hot and/or cold recording sensors
are permanently positioned/fixed and need to be relocated, additional TUS temperatures shall be performed to
verify that the new locations are correct throughout the qualified operating temperature range of the furnace.
3.5.15.4 If the hot and/or cold recording sensors are not permanently positioned/fixed, they can be relocated without the
above testing if there is a diagram of the required location where the hot and cold recording sensors will be placed
at each process temperature.
