Memory rate
(storage cycle)
The storage cycle is set here. Depending on the setting for the parameter
Stored values, the measurement data are saved after the set time has elapsed.
The smaller the storage cycle, the more data must be saved.
Min. memory
rate
(Eco mode)
The storage cycle is set here, that will only be used if Eco mode is active. If no
signal changes occur in Eco mode, no measurement data will be saved. This
parameter is used for forced storage at the rate that was set. This provides the
additional security that the connected sensing system is functioning.
Tolerance band
(Eco mode)
The tolerance for Eco mode is specified here. If, in Eco mode, the deviation of
the present value from the value that was last stored is larger than the
tolerance entered here, the present value will be stored (if the storage cycle
has elapsed at the same time). The tolerance always refers to the current
scaling of an analog channel within the current group.
Eco
Mode
Using this method, the value is stored if the
measurement differs by a certain amount from the value
that was last stored, or if a binary channel belonging to
the group alters its state.
In Eco mode, the configured storage cycle is regarded
as the maximum storage rate. In no case will values be
stored any faster, even if they change faster. The
momentary value is always used for investigating the
tolerance band, and only at the instances of time of the
storage rate that was configured.
If a measurement is saved in Eco mode, it will, at the
same time, be used as the new reference.
H
If the storage cycle is set to 0
(= 125msec), then not 1 measurement but
8 will be stored.
H
If the “Min. storage cycle” is smaller than
the “storage cycle”, Eco mode will
become ineffective, i.e. the momentary
values are stored.
H
If 0 is set, the recorder uses the fastest possible rate, i.e. it saves
the measurements every 125msec (high-speed mode).
