7.0 Calibration
The calibration procedure maintains the scale accuracy within specifications and can serve as a performance
test procedure. Your IQ6200/6500 scale should be on for 30 minutes before attempting to calibrate. Use the
following procedure to calibrate:
1. To enter calibration mode, press and hold REZERO while entering 8 7 1 5 on the keypad. The
Quantity window displays the raw count.
If the unit will not allow you to enter calibration mode, the calibration lock-out switch may be ON.
To find out, hold down REZERO and enter 2 8 4. If the lock-out switch is ON, contact the factory
for assistance.
2. Use + or – to adjust raw count as close to 30,000 as possible.
3. With no weight on the scale, press REZERO.
4. Add known weight to scale. At 100% capacity, quantity window should show values close to those
listed below:
IQ6200 105,000, except for capacities of 1.5, 15, 150, 1500, or 150,000 lb. IQ6200s
configured for these capacities should show a raw count value close to 90,000.
IQ6500 530,000
Known weights other than pounds and kilograms can be used. See SPEC10 bits 2 and 3 in Section 6.
If bits 2 and 3 are 00, scale will not change from type of unit used to calibrate it.
5. Using TARE to increase or PIECES to decrease, adjust span count as close as possible to the value
shown above.
6. Remove weight from scale. If necessary, readjust zero raw count to 30,000.
7. Press REZERO.
8. Repeat steps 4—7 until both zero and span readings are as close as possible to the desired values.
9. Add known test weight to scale for final span calibration.
10. Enter value of weight on scale, including decimal places, using numeric keypad (for example,
50.000).
11. Press * to calibrate span.
12. Press MODE twice to exit calibration mode.
