7.  Trip if source  < / > Set -- Choosing source>set means that the limit will be activated 
when the source becomes larger than the set point.  Choosing source<set means the 
limit will be activated when the source becomes less than the set point. 
8.  Latching on/off -- Selecting latching off means that the limit will be de-activated 
automatically when the source passes the reset point (see next selection).  Selecting 
latching on means that once the limit is activated you must manually reset it using the 
Reset button.  If you select latching on then the limit setup is done. 
9.  Rst -- This selection determines the numerical value of the source at which the limit 
will be deactivated (reset point).  If you selected “source>set” in step 7 then the limit is 
deactivated when the source is less than the reset point.  If you selected “source<set” 
in step 7 then the limit is deactivated when the source is greater than the reset point. 
 
Notes: 
The Set and Reset conditions for each limit are evaluated independently.  If both 
conditions are met then Reset will take priority over Set. 
Limit status may show an asterisk if the limit is enabled but there is an error in the signal 
source.  For example, if the limit source is load but there are no load cells currently 
calibrated, or the load cell has a rating of 0.0 Lb, or a millivolt per volt constant of zero.  
Another example would be if the limit source is position and zero has been entered for the 
encoder counts-per-inch constant.  Limits that are in this error condition will be forced to 
the off position as if they were disabled. 
>System Options 
This menu contains some system wide parameters that are seldom changed.  These are 
listed in a submenu that works exactly like the setup mode main menu. 
    >>Printer Baud 
The front panel print button and the RS232 print commands will use this baud rate for 
communication with your printer.  This setting has no effect on units that are not 
equipped with the printing option.  57.6 K baud is commonly used on older serial 
printers (Epson Stylus II), 230.4 K baud is used on more recent serial printers (Epson 
Stylus Color 600, Color 800). 
    >>Auto Identify 
This allows you to turn automatic cell identification on or off.  Usually you can leave 
auto-id on even if you never use automatic cell identification.  In order to use this 
function you must either have an auto-id equipped cell or use an in-line auto-id module 
attached to your cell cable. 
    >>Auto Zero Ch A/B 
This menu lets you enable or disable auto zeroing for measurements on Channel A or 
B.  When enabled, this function will tare the load or torque to zero any time that it has 
remained within 10 counts of zero on the display for 10 seconds.
