13.2.3 High-resolution verification registers
When the meter is in verification mode, reading of two high-resolution verification registers is opened: a volume
register and an energy register.
These registers are integrated at the same time as the legal volume and energy registers, with the same values.
However, the units of the high-resolution registers must be [ml] for volume and [10mWh] for energy, whereas the
units of the legal registers can be configured depending on meter size.
13.2.3.1
As long as the meter remains in verification mode double key pressure – i.e. both keys remain pressed for 5-6
seconds – functions as reset of the high-resolution verification registers. Thus, both registers are reset.

13.2.4 Verification pulses
When the meter is in verification mode it can emit verification pulses with a resolution that appears from the table
in paragraph 13.3.3.
The verification pulses are established via plug-in module 402-0-11. The pulse outputs are galvanically separated
from the meter. (Pulse Interface type 66-99-109 cannot be used for MULTICAL
