8.3.1.B Perform Span Calibration
To get here, navigate:
[MENU]CALIBRATION MENUBALANCE CALIBRATION MENU
PERFORM SPAN CALIBRATION
Span calibration should be done:
• Immediately after initial setup and
60-minute warm-up from cold start.
• Whenever the instrument is moved.
• Whenever a problem is suspected.
• As your quality policy dictates.
Performing the calibration:
• Select the PERFORM SPAN
CALIBRATION menu item.
• The introduction screen is displayed; press [GO] to continue.
• The heat chamber must be less than 50 °C; otherwise the instrument delays the
calibration until the chamber cools adequately. If this occurs, the lid can be opened to
speed up the cooldown.
• Follow the instructions. A 20g weight is used to calibrate the balance. The weight is
loaded twice during the span calibration: one time for calibration and a second time for
verification. During the weight loading and removal, avoid excess pressure on
the balance. Use the tweezers included with the MAX
®
4000 to gently place the
weight on the pan.
• After successful calibration, the calibration report is displayed.
• If the calibration routine failed or the verification weight value fails, rerun the
calibration. If the calibration fails again, contact AZI Customer Service.
