8.4 Adjustment of the internal calibration
Together with the fully automatic and/or time-controlled self-calibration (adjustment) proFACT, with noncertified versions of the
PR/SR balances you can choose to configure the internal calibration (adjustment) to your weight standard if a test of the balance
with this reference weight shows that the deviation is larger than that specified in the technical data (see section 7.2.2 under
"Long-term stability of the sensitivity"). The better the following requirements are met, the more exactly can be internal calibration
(adjustment) be adjusted.
Requirements
• The balance is leveled (section 2.3).
• The balance has been connected to the power supply for at least 4 hours.
• There are no excessive drafts at the balance location, use draft shield if necessary.
• No excessive temperature fluctuations are present (see section 2.2).
• You have one of the selectable weights available (see section 8.2.4) with the greatest possible accuracy.
Important
Before you start the adjustment
• Ensure that you have taken the deviation of your weight standard from the nominal value into account in the determination of
the sensitivity deviation.
• Note that the balance only takes into consideration the nominal value of your weight in the adjustment, e.g. 5000.00 g and
not the actual value, e.g. 5000.013 g.
