Maximum/Minimum Readings
The max & min readings (peak & valley) reached by the process can be displayed either continuously or
momentary:
1. Display briefly by assigning to the digital inputs in the
User
menu.
2. Display continuously by assigning either display to max/min through the
Display
menu.
Changing the programming of the F1-F3 function keys will
disable the default batch operation of these keys, and is not
recommended for batch control applications.
Any of the digital inputs can be programmed to reset the max & min readings.
To display max/min readings continuously:
Assign either display to Max (
d Hi
), Min (
d Lo
), or toggle between Max and Min (
d HL
) every 10
seconds.
Noise Filter (
filter
)
The noise filter is available for unusually noisy signals that cause an unstable process variable display.
The noise filter averages the input signal over a certain period. The filter level determines the length of
time over which the signal is averaged. There are two available settings: Hi Speed and Lo Speed
(programmable from 2 to 50).
Noise Filter Bypass (
bypass
)
The noise filter bypass changes the behavior of the controller so that small variations in the signal are
filtered out but large abrupt changes in the input signal are displayed immediately. The bypass value
determines the minimum amount of signal change to be displayed immediately. All signal changes
smaller than the bypass value are filtered or averaged by the controller. The noise filter bypass may be
set between 0.1 and 99.9% of full scale.
Rounding Feature (
round
)
The rounding feature is used to give the user a steadier display with fluctuating signals. Rounding is used
in addition to the filter function.
Rounding causes the display to round to the nearest value according to the rounding selected. This
setting affects the last two digits, regardless of decimal point position.
!
Note that changing default the
programming of the upper or
lower displays will interfere with
seeing the batch total (upper
display) or rate (lower display) of
the batch process.
