6.2 Keyboard control functions
The four-button keyboard allows for a wide range of the meter functions to be controlled and modified with respect
to the requirements of particular operating conditions at the user’s plant. The push-buttons T1 to T4 are provided with
the following graphic symbols:
T1
T2
T3
T4
The push-button control of the meter is shown in a schematic diagram in Fig. 17. The system can be operated in
two different modes where the switching-over action between the operation modes and individual functional blocks
within a selected mode can be initiated by depressing the push-button the image of which is depicted at the given
transition
position.
From
the
diagram
it
follows
that
a transition from one block to the next one (on the right-hand side) will be done by depressing the T2 button, while a
transition to the previous block (next on the left-hand side) by depressing the T3 button. The Zero Reset block can only
be activated in the cases of technological meters (the software switch in the “NF” position). In the case of commercial
(invoicing) meters, where the switch is in the “F” position, the Zero reset block is missing.
Upon energising, the meter will automatically adopt the display mode with the pre-selected (initial) quantity
displayed (see description below). The display mode will also become operative if no push-button has been depressed
over the period of 300 measurement cycles (5 minutes for a measurement cycle of 1 s).
