digits, buttons
[^]
and
[v]
enable switching between more and less significant digits.
Positions of currently displayed digits are signalized by flashing decimal points (see
example below).
Example of switchin
g between less and more significant digits of total flow result .
Let, total counter result be equal 1236789876543.21:
–
while less significant 6 digits are displayed, flashing most left decimal point signalizes
that result is longer than 6 digits, to show more significant digits press
[^]
,
–
while medium digits are displayed both most left and most right decimal points are
flashing (Figure 6.1). Most right decimal point signalizes than result has less significant
digits – to see these digits press
[v]
button. Most left decimal point signalizes
additional more significant digits. Press
[^]
button to see these digits.
–
while most significant digits are displayed, most right decimal point is flashing, and
signalising that result has less significant digits, to see these digits press
[v]
.
Figure 6.1. Switching between digits (screens) of total flow result.
All accessible parameters (e.g. pulse input settings, decimal point position) can be
changed by entering the menu (see:
DEVICE PROGRAMMING
). Use the local keyboard or
the remote controller to do it. (Note: all parameters can be remote changed via RS-485
interface).
Counting of pulses and controlling or relays is realised regardless of operation mode
(after entering to menu mode counting and controlling is continued in “background”.
