Approvals

3.5.1 ATEX, IECEx, UL, CSA

See a sample of approval label on the fold-out page. There is
also a printout of the approval label inside the shipping box of
the instrument.

3.5.2 Marking

The marking is reproduced on a separate piece of paper
shipped with the instrument.
Serial Number key: The third letter of the serial number
specifies the manufacturing year: M = 2019, N = 2020, P =
2021, R = 2022, S = 2023, T = 2024, U = 2025, W = 2026, X =
2027, Y = 2028, Z = 2029, etc. (Letters G, I, O, Q are omitted)
Example: Serial Number ARMB-0001: the third letter is M,
which means that the unit was manufactured in 2019.
