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.
In order 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 instruc-
tions on how to program numeric values see Setting
Numeric Values on page 19.
Making Changes to a Password
Protected Meter
If the meter is password protected, the meter will dis-
play the message LOCKED when the Menu button is
pressed. Press the Enter button while the message is
being displayed and enter the correct password to
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 UNLOCKED and will no longer require a pass-
word to access Programming Mode.
Note: If the meter is password protected and the
password has been forgotten, the password may be
overridden using the master password: 50865
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
input (located on the signal input connector) to access
some of the menus or to activate certain functions
immediately (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.
