Cooper Instruments & Systems DFI 250X Digital Weight Indicator - Manual (Page 21)

CF 147 17 version 1.1
used to dampen unwanted weight fluctuations caused by vibrations or dynamic forces. High settings will
stabilize the display at the expense of rapid response to sudden weight changes.
•
Options are: NONE, 0.2, 0.5, 1.0, 2.0, 3.0, 4.0 (time in seconds)
•
Default: 0.5 (seconds)
•
MOTION (Motion Detection)
Sets how much weight variation over a defined time period is allowed before the displayed weight is deemed to
be unstable. This value is displayed as weight change (0.5 or 1.0 graduations) per second. When set to OFF,
the Motion Detection is ignored and ZERO, TARE and PRINT actions are instantaneous.
•
Options: OFF, 0.5-1.0, 1.0-1.0 (graduations per second)
•
Default: 0.5-1.0 (0.5 graduations per second)
•
INIT.Z (Initial-Zero on Startup)
This function can be used to automatically ZERO the indicator during power-up. The amount of weight that can
be zeroed is limited to +/– 10% of full scale.
•
Options are: ON or OFF
•
Default: OFF
•
Z.TRAC (Zero Tracking Sensitivity)
Zero tracking allows the display to adjust for minor changes in the zero balance of the scale. When enabled,
the instrument will track weight readings within the zero 'dead' band back to exactly zero at a maximum rate of
0.5 (SLOW) or 10 (FAST) graduations per second.
•
Options are: OFF, SLOW, FAST
•
Default: OFF
•
Z.RANGE (Allowable Zero Operating Range)
This setting restricts the range over which the Zero functions can operate.
•
Options are: -2_ 2, -1_ 3, -20_20
•
Default: -2_ 2 (–2% to +2%)
•
Z.BAND (Zero 'Dead' Band)
This is an adjustable margin either side of true zero that defines the zero 'dead' band. The zero 'dead' band is
used by the automated functions to determine zero load (e.g. a setting of 4 specifies that readings between –
4.5 and 4.5 are considered to be zero).
When the displayed weight reading is within this band the instrument displays the zero band annunciator.
Refer to Status Annunciators section 5.1.1.
•
Settable over the full weight range. Always enter a number in multiples of display units. Refer to RES (Count-
by Resolution) section 7.4.1 for more information.
•
Default: 0 (i.e. –0.5 to 0.5 graduations)
7.4.3 CAL (Scale Calibration)
Items within this group perform various calibration routines. For detailed scale calibration procedures refer to
Calibration section 8.0. Certain items in the Scale Build can affect the calibration of the scale. Always check that
these sections are correctly configured to suit the current application before attempting to calibrate the scale.
•
ZERO (Zero Calibration)
Select to perform Zero Calibration. While the zeroing is in progress the display will show Z.in P. Refer to ZERO
(Zero Calibration Routine) section 8.1.1.
•
SPAN (Span Calibration)
Select to perform Span Calibration. While the span calculation is in progress the display will show S.in P. Refer
to SPAN (Span Calibration Routine) section 8.1.2.
•
ED.LIN (Edit Linearization Points)
Select to view linearization setup and start linearization routines. While linearization is in progress the display
will show L.in P. Refer to ED.LIN (Edit Linearization Points) section 8.3.1 for more information.
