KROHNE C95 CI EN - Manual (Page 3)

S
The C95 CI is a totalling digital panel meter. The totalling function allows
converting any instant value, after integration, into a cumulated magnitu-
de.
It can be connected to a flowmeter to display the instant flow and the
cumulated volume or weight, and also to a converter, for instance a
power converter to display the instant power and the energy consump-
tion of an installation.
General features
- Instant value display on 5 digits (14mm) with scale factor adjusting
from -99 999 to 99 999
- Cumulated value display on a 6 digit counter (14mm) associated with
a second overstepping counter, allows totalling from -99 999 999 to
+999 999 999
- Totalizer memory saved in case of power supply cut
- Programming of the integration time (sec, min, hours) and of
a convertion coefficient (from 0,0001 to 999999)
- A bargraph allows a quick evaluation either of the instant value or
the cumulated value, and can also be used as indicator for various
functions (overstepping, LOGIC input, RS, etc...)
