Be sure to key in the password '127' before pressing and holding the ESCAPE key if you want to change items in the service menu, otherwise you will only be able to view them. Figure 10 Setup menu Units submenu The first submenu under Setup is Units.
Units Unit 1 The unit of measure you choose for this item will be assigned to the annunciator labeled “lb f” on the front panel. You can also choose a length unit of measure for torque loadcells. Following is the list of units of measure: Pounds F* = pounds force 1000g F = kilograms force N = Newtons 1000 N = 1000 Newtons g F = grams force OZ F = ounces force Ton F = tons force Tonne F = tonnes (metric tons) force Other = Allows you to define a custom unit of force.
Loadcells submenu The next Setup submenu is Loadcells. Use this menu, shown in Figure 12 to linearize and configure each loadcell in your system. Cell 1 This is the first loadcell in a list of loadcells. Cell 2, Cell 3, etc. are available by pressing the MENU key if they are configured. To add loadcells to the system, press the +/- key while End is displayed. To delete the last loadcell from the list, press ZERO while that Cell # is displayed. The FI-127 supports up to six loadcells.
Use these keys to navigate through the menus: ESCAPE = ENTER = ← = MENU = up down left right Figure 12 Loadcell submenu 27
Reset Use this item to reset the calibration points to factory default values. If you choose yES the values are set to 0 lbs f at 0 mV/V and 5000 lbs f at 1 mV/V. Print Lets you print the calibration values for a selected loadcell. See note at left. Choose from No or Yes. If you choose Yes, the information is output to port 1.
Bust Use this to enter a break percentage. Break percentage is the drop in force which the indicator will interpret as a break detection. This is entered as percentage of full capacity. 10% is the default value. The output signal is asserted when a break is detected and switches to the inactive state whenever you perform a zero or peak reset. Capture Use this to enter a capture percentage. Capture percentage is drop in force occurring before a rebound in force to an ultimate peak of force.
Average Use this to configure the number of intervals to average for each force display. This can be entered in one of two methods: x disp. or x a-ds. Press the UNITS key to switch back and forth between the two choices. The suggested method of setting the average is by picking a value for x disp. Doing this insures that a multiple of the display rate is always being averaged. This results in a steadier weight display. Use x a-ds if you need an exact number of A-D conversions for your particular situation.
Over When using overload or over capacity alone, set the other menu item to its maximum value to disable any conflicts. This submenu lets you setup the overload and capacity setting which cause the O. load error message. Overload - This value is expressed as a percent of capacity referenced from the deadload determined by calibration. Overload is restricted to 200% or lower. 105% is the default value. Over Cap.
Options submenu The next Setup menu item is Options. Use this to configure the way your FI-127 works. Below is the entire menu structure located under this item. See the following pages for descriptions of these menu items.
Buttons Use this to enable or disable the following front panel keys: Select - Choose Yes or No to enable or disable the SELECT key. Units - Choose Yes or No to enable or disable the UNITS key. Reset - Choose Yes or No to enable or disable the PEAK RESET key. Send - You have two items to configure in this submenu. PB Send - Use this to determine which layouts are sent to which ports for pushbutton data send.

Freeze Force Function Control Whenever a ‘freeze’ action (assigned to hardware input and/or a serial input character) is executed, the current a-d value (at the output of the low-pass filter) is captured, or “frozen”. An ‘unfreeze’ action (assigned to hardware and/or a serial input character) may be used to “unfreeze” the force value. These actions can only be executed while the instrument is in the display mode — they are ignored at any other time.
Data Capture Control Whenever a ‘Capture’ action (assigned to hardware input and/or a serial input character and/or Capture Start in the user menu) is executed, data capture is initiated. The current time and date are saved, and points are stored in memory at the configured capture rate. A ‘Stop Cap.’ action (assigned to hardware and/or a serial input character and/or Capture Stop in the user menu) may be used to halt the data capture.
