Graduations 

Specifies number of full-scale graduations. Value should be consistent with legal 
requirements and environmental limits on the useful system resolution.

Span Gain

 

Span Gain is related to A/D integration time. The larger the span gain, the higher the 
internal resolution, but the slower the update speed. Note that the scale must be re-
calibrated whenever this parameter is altered. See Appendix C for more information.

F3

 

Zero Track Band

 

Selects the range within which the scale will automatically zero. Note that the scale 
must be in standstill to automatically zero. Selections are in Display Divisions. 

0d

 0.5d

 1d 3d  5d 

F4

 

Zero Range

 

Selects the range within which the scale may be zeroed. Note that the indicator must 
be in standstill to zero the scale. 

100% (US)

 

1.9% (CE) 

2% 

F5

 

Motion Band

 

Sets the level at which motion is detected by comparing the present display update 
with the previous one. If motion is not detected for two seconds or more, scale is in 
standstill and can process a Print or Zero command. Maximum value varies depending 
on local regulations. 

0.25d (CE)  1d (US)

 3d 

5d 10d

F6

 

Digital Filter

 

Averages weight readings to produce higher stability. The higher the filter setting, the 
greater the stability but the slower the indicator’s response time. Choose 8 unless a 
very fast response is needed.  

1          2

F7

 

Overload Limit

 

Selects the desired formula which determines the point at which the indicator shows 
overload. All selections are based on the primary unit selected in F8. "FS" = Full scale 
in primary units.

Calib. Unit

 

Selects the primary base unit to be used in the calibration process. Also the default unit 
for normal operation. 
"1" = primary unit is lb.                       "2" = primary unit is in kg.

sequence 

F18

 

View Calibration

 

Actuates the function that allows you to view both the zero and span calibration value. 
The values displayed in this function are valid only after Calibration (F16 & F17) has 
been successfully completed. Scrolling down with the 

ZERO

 key one level begins the 

procedure. 

Press 

ZERO

 key to begin 

sequence 

F19

 

Key-in Zero

 

Allows you to key-in known zero calibration value in case of memory loss in the field. 
Scrolling down with the 

ZERO

 key one level begins the procedure. 

Press 

ZERO

 key to begin 

sequence 

F20

 

Key-in Span

 

Allows you to key-in a known span calibration value in case of memory loss in the 
field. Scrolling down with the 

ZERO

 key one level begins the procedure. 

Press 

ZERO

 key to begin

Factory Reset

 

This sub-menu will reset all parameters in the “F” and “A” menu to the default 
settings. USE WITH CAUTION!
