Parameter LCD CONTRAST
Low/Medium/High Value: Low or Medium or High
Units Low/Medium/High
This parameter tells the Model 880 how to control the bias voltage to the LCD. Adjust for best
viewing: brightest with the most contrast at the desired viewing angle. Between 45° above and
perpendicular to the LCD viewing surface is best (@25°c±5°).
____________________________________________________________________
Parameter PASSWORD LOCK #
Lock Code Value Range is 0 - 9999
Units None
This allows changes of Model 880 program parameters to be restricted to only those people
knowing this 4 digit password code. If password lock is programmed with a non-zero value, whenever you
access a menu that can change a parameter or try to change a parameter, the Model 880 will ask you for the
password. The exceptions are the I/O Programming menus and the Communications Setup menu that are
password locked by a Lock Code parameter found on the Communication Setup menu (see
Communications Setup Configurations in the following section).
Caution
CAUTION If this password is entered inadvertently or forgotten it can be removed by
purging the unit of all its stored parameters. When this is done all program parameters including I/O
programming, System Configuration, Process Lists and Film Parameters will be lost and require
reprogramming. This could be several hundred items of data. All this data should be recorded prior to
purging the memory of the Model 880. Recording methods include downloading to a PC from the HOST
port, information written down by making a paper copy of the various parameter tables and circling the
selected element, downloading to the memory module. To purge ALL stored data from the Model 880,
press the fixed MENU key when on the Run Time screen then select the Service key on the MAIN menu.
Press the Purge (All Stored Data) key and the confirming ACCEPT key. After doing this the Model 880
will contain no user programmed information and will have to be completely reprogrammed.
If password is forgotten and programming has not been saved in some other
media, call factory to eliminate passwords without purging memory.

Parameter RUN NUMBER
Run Number Value: 0 - 9999
Units None
RUN NUMBER
The run number auto-increments with the start of each new process [Sequencing: on process start.
Non-sequencing: on Film start.]. The number entered with this parameter
should be thought of as a pre-usage offset as the run number increments
when the process or film starts. For example, if the run number entered is 2,
the next process that is started will have the run number of 3. Run
number is used to identify a specific process run. Run results can be compared by viewing the PROCESS
ACCOUNTING screens (See PROCESS ACCOUNTING in section x.x).
