IQ9500 Installation Manual
The following steps explain the calibration
procedure:
1. Press and hold the
REZERO
key and enter
8715
on the keypad to enter calibration mode.
The
QUANTITY
displays the raw count.
2. With no weight on scale, press the
CODE
key
to compute zero. The
QUANTITY
display will
show a count of approximately
100000
. If the
QUANTITY
display is not 100,000 ±10,000,
use the
+
or
–
key to adjust until the display is
within range. Another option is to press the
CODE
key to automatically recompute zero.
3. Press the
REZERO
key to zero the weight (if
needed) in the
WEIGHT
display.
4. Place a known test weight on scale.
5. Adjust displayed weight as close as possible
to the known test weight by using
TARE
key
to increase or
PIECES
key to decrease the
value.
6. Enter the known calibration weight (including
all trailing zeros) using the numeric keypad.
7. Remove the test weight from the scale to
verify that the zero value has not shifted. If
the value in the
WEIGHT
display is not zero
(has shifted) press the
REZERO
key.
8. Place the known test weight back onto the
scale. If you had to adjust the zero value you
will notice that the weight value has also
changed and is closer to the true value.
9. Press the
*
key to start span calibration.
10. Remove weight from scale.
11. Press the
MODE
key once to exit calibration
mode.
12. Press the
MODE
key once to return to the
weighing mode.
13. Place the test weight used to calibrate span
back on scale and verify proper weight. If the
displayed weight value is not equal to the
known test weight, repeat Steps 1 through 12.
NOTE:
If you are using a multiple scale configuration, it
will be necessary to calibrate all scales individually using
Steps 1 through 13. Use the
SCALE
key to switch
between scales.
