PD6600 Series Loop-Powered Process Meters
Instruction Manual

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 of time. The filter level determines the length of
time over which the signal is averaged. The filter level
can be set between 1 and 16 seconds or turned off.
The higher the filter level, the longer the averaging
time and so the longer it takes the display to settle to
its final value. Setting the filter level to off disables the
filter function.
Noise Filter Bypass (
BYPAS
)
The noise filter bypass changes the behavior of the
meter 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 by-
pass value are filtered or averaged by the meter. The
noise filter bypass may be set between 0.1 and 99.9%
of full scale.
Enabling Password Protection
(
PASSWRD
)
The
Password
menu is used for programming security
to prevent unauthorized changes to the programmed
parameter settings.
To set a password, enter the
Password
menu and
program a five-digit password. When a password has
been enabled, the lock icon will display in the lower
right of the display (PD6602/6 only). For instructions
on how to program numeric values see

gain access to the menu. After exiting
Programming
Mode
, the meter returns to its password protected
condition.
Disabling Password Protection
To disable password protection, access the
Password
menu and clear the entered password either by press-
ing and holding the
Right Arrow
button until all digits
reset to zero or manually changing all the digits to
zero. When the
Enter
button is pressed, the meter will
display

word to access
Programming Mode
.
Note:
If the meter is password protected and the

Programmable Function Keys User Menu
(
USER
)
The
User
menu allows the user to assign the front
panel function keys F1, F2, and F3, and the digital in-
put (located on the input signal connector) to access
some of the menus or to activate certain functions im-
mediately (e.g. reset max & min, hold relay states,
etc.). This allows the meter to be greatly customized
for use in specialized applications.
Tare (
TARE
)
The tare function zero’s out the display. In the case of
scale weight, tare is used to eliminate container
weight and provide net weight readings. There are
two tare functions; Tare and Reset Tare. When the
tare function is used, the display reading is offset by
the displayed amount to make the displayed value
zero. Reset tare removes the display offset of the net
value, and the gross and net values become the
same until a new capture tare is entered.
Program a function key or the digital input for the tare
and reset tare.
