9 Calibrate the FLSC 05 with FLI 225
For Span Calibration:
NTEP/Handbook 44 requires that the scale be calibrated to at least 50% of the scale’s
rated capacity. A minimum of 12.5% or 1000 lb. (whichever is greater) of the scale’s
rated capacity in certified test weights is required for calibration. If you do not have 50%
of capacity in certified weight available, you will need to use the Substitution test
method (Buildup Calibration) to reach the required amount of weight. This weight must
include the required certified weight.
For Angle (16 Point) Calibration:
When performing the Angle Calibration, you will actually need two known weight
values; full weight and half weight. Full weight (span weight) does NOT need to be
equal to the full capacity of the scale. Half weight must be equal to 50% of the full weight
value. For example, if you used 2000 lbs for full weight (span weight), you will need to
use 1000 lbs for half weight.
9.1.1 Determining if Calibration is Needed (NA)
Calibration of the FLSC 05 with FLI 225 may be required when:
l
The system fails one of the following calibration tests
l
A Weigh Bar is replaced
l
The FLI 225 is replaced
l
The FLJ 100 is replaced
Calibration Test Method 1 (NA)
Calibration Test 1 uses 1000 pounds of certified test weight to establish if the
Avery Weigh-Tronix legal-for-trade forklift scale requires recalibration. If the displayed
weight is anything but 1000 pounds, follow the instructions for the indicated calibration
procedure.
1. Configure the indicator to display in 5 lb divisions. See page 58.
2. Disable Automatic Zero Tracking (AZT). See page 60.
3. Position the forks centered over the Weigh Bars.
4. Place a sturdy pallet on the forks.
5. With the forks raised, press the ZERO key to zero the scale.
For complete scale calibration, follow your local weights and measures
requirements.
