•^ User Problem
A balance needs to be calibrated
2
and
adjusted.
- on regular base.
- after temperature change.
- every time a balance was physically
moved.
- every time it was leveled.
Very often the user is obliged to
keep a calibration history.

Sartorius Solution
Secura is equipped with isoCAL. IsoCAL is
an internal calibration and adjustment per-
formed automatically with the fluctuation
of temperature or by a timed interval.
The internal calibration is performed by
a motorized weight located inside the
balance. Every time isoCAL is performed, a
calibration report is generated and stored
for traceability. Retrieval of this calibration
report is called Cal Audit Trail. External
Calibrations are also stored in this memory.

How to Demonstrate
10 sec. after leveling, Secura will automatically self-calibrate (isoCAL).
- Safety level is set to "High" and
- isoCAL is set to "Automatic" {/* -* Calibration | Adjustment -» isoCAL).
- Within this 10 sec. "isoCAL" is shown. Touching this will also start the isoCAL.
- Behind the menu button ^^g you will find "CAL" on the left side. Behind that you
will find "CAL-lntern" which also starts the intern calibration and adjustment routine.
After the routine has ended a calibration report will appear. See chapter 9 "Customers
section" for example to show.

Calibration history is stored sequentially (dated) in Secura in day by day order.
{/" -* Calibration | Adjustment -» Calibration report). User will find up to 99 reports
per day stored for 30 days.

The commonly used term ..Calibration" means actually calibration and adjustment. While the meaning
of "calibration" is actually describing the determination of a deviation, "adjustment" is describing the
correction of the determined deviation. In this chapter we will use both terms in its original meaning.

Intensity is depending on the settings for "Safety level".
