Accuracy:
± 2 Minutes/Month (15 till 30°C)
trimmable via PC-Software
Synchronization via:
Measurement input,
HV-Input 110/230 V AC,
Synchronization pulse (digital in-
put)
Running reserve:

Response time
The total response time is the addition of the measurement
time t
of the input quantities and the processing time t
1
the respective output (analog output, bus, digital output,
relay).

7.5 Logger and lists (optional)
By means of these options measurements and events may be
long-term recorded. Depending on the application 7 different
kinds of data may be acquisited:
– Progression of mean-values with interval time t1
(1s...60min)
– Progression of mean-values with interval time t2
(1s ... 60min)
– Min/Max values during interval t3 (1s ... 3h)
– Meter readings
– List entries of alarms
– List entries of events
– List entries of system messages
They share the available storage space of 64Mb size. The
memory allocation may be performed using the CB-Manager
