Verification process

For all verification processes, both the corresponding approvals and the country-specific regulations
must be observed.
For verifying low-pressure gases (gas ≤ 100 bar (≤ 1450 psi)) the separate document "Verification

Setting up custody transfer mode

The measuring instrument has to be operational and not set to custody transfer mode.
1. Configure the functions important for custody transfer measurement, such as the output
configuration, custody transfer variable and the measuring mode.
In the "CUSTODY TRANSFER" block (function block Z; functions Z001 to Z008), the outputs
relevant for custody transfer measurement can be set to custody transfer and the current
custody transfer status can be displayed.
In the "OUTPUTS" block (function block E), the custody transfer variables can be assigned to
the existing outputs.
In the "INPUTS" block (function block F), a switching behavior is assigned to the input.
For NTEP and MC only: The "CUSTODY TRANSFER" block is hidden. All relevant outputs are
set to custody transfer.
!
Note!
Please refer to the separate Device Functions manual for a detailed description of the functions.
2. Once all the functions relevant to custody transfer have been configured, the custody transfer
code is entered in the "ACCESS CODE (2020)" cell.
Custody transfer code: 8400
The functions are locked once you enter the custody transfer code. These functions are marked
with a keyhole symbol in the separate Device Functions manual (`).
3. The lead stamping of the measuring instrument (see illustration below)
