AD-4407A Weighing Indicator
5.3.1.
Selecting the Division and Range
Consider the following rules to design the weighing range.
Rule 1 Select the division and range of each weighing range so as to satisfy the following
inequality.
The first range < the second range
The division of the next weighing range is automatically set larger than the
division of the lower weighing range. Changing the division is possible.
Rule 2 When specifying the dual range, the upper limit value of the second range
becomes the maximum capacity.
Rule 3 Select a resolution smaller than 40000. The resolution is a value obtained by
dividing the maximum capacity by the minimum division of the first range.
5.4.
Digital Linearization Function
Even if the zero and span calibration have been completed, there may still
remain a linearity deviation caused by the performance of the weighing unit.
The digital linearization function can rectify or reduce the linearity deviation
using weighing points except zero and capacity. Up to three weighing points
can be specified.
Caution This function does not improve repeatability or hysteresis.
Use the mass on the condition that
lnr 1
<
lnr 2
<
lnr 3
.
Do not press the
ENTER
key while the STABLE mark is off.
Step 1 When
Cal 0
is displayed, press the
MODE
key to display
lnr 0
.
Step 2 Enter the zero point. Refer to “5.2.3. Zero Calibration”.
Step 3 The value of the middle point is displayed after indicating
lnr
x
. x is 1, 2 or 3.
The triangle mark of the same number(x) is displayed along with the value.
Step 4 Select a middle point.
If you want to cancel the current procedure, press the
ESC
key to finish this
function. Proceed to step 7 and other points are cleared (canceled).
Select a middle point value using the
0
-
9
keys. Proceed to step 5.
Step 5 Place a mass equivalent to the displayed value on the weighing unit. Wait for
the STABLE mark to turn on and press the
ENTER
key. Proceed to step 6.
Step 6 If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each point.
If you finish this function, proceed to step 7.
Step 7 Perform step 11 of "5.2.4. Span Calibration" immediately.
