fluctuations can be falsified by "smoothing out" the ascending and descending
slopes, or by eliminating short pulses. The filter time constant should be customized
to the maximum speed of changes in the measured process.
[5]: It enables on/off the archiving of the results to a file in internal archive memory.
[6]: The failure value is the constant value which is displayed instead of the
measurement result if the input signal fails or calculation result is out of range.
11.4.3 Totalizers
Fig. 11.6 An example
view of the 'Channel’ setting window – Totalizer 1 (Σ1).
Mode: Disabled
(Disabled, Unresettable, Resettable, Daily, Weekly, Monthly)
[1]
Unit: [None]
(text)
[2]
Multiplier: 1
(0.001, 1, 1000)
[3]
Resolution: 0
(0, 0.0, 0.00, 0.000, 0.0000)

Archiving: Disabled
(Disabled, Enabled)

[1]: Each totalizer may be set in one of the six options:
Disabled
– values are not
counted,
Unresettable
– user cannot zero the totalizer,
Resettable
– user can zero
the totalizer at any moment,
Daily
– the totalizer resets at 0:00 every day,
Weekly
– the totalizer resets at 0:00 every Monday,
Monthly
– the totalizer resets at
0:00 every first day of month.
[2]: The unit is provided for reference purposes only. User can enter any unit which does
not affect the results displayed by the device.
[3]: The multiplier allows multiplication of the measurement results by one of the three
values selected from the list. For example, if a flow meter is connected to the device
measuring the flow in m
3
/s and the user wants the result to be displayed in dm
3
/s, the
multiplier should be set to 1000. In a reverse situation, when the measurement would
be made in dm
3
/s and the user would like the values counted by the totaliser to be
displayed in m
3
/s, the value of the multiplier should be set to 0.001.
CAUTION!
It has to be remembered that the multiplier value does not determine
the displayed unit and vice versa.
[4]: The number of decimal places displayed. It has no effect on the calculation accuracy
and can be changed any time without affecting the totalizer status.
[5]: Enables on/off the totalizer archiving. Selecting the check-box is equivalent to
switching on the archiving.
