Automatic Calibration/Adjustment
with isoCAL
Fully automatic calibration/adjustment ensures that the balance is automatically
calibrated and adjusted when predefined time intervals or temperature values are
exceeded.
This function varies in different models:
– Secura
®
: isoCAL is automatically carried out based on time or temperature,
andeach time the balance is leveled. This function can be switched off via the
system settings (see “Calibration/Adjustment” on page28).
– Quintix
®
: isoCAL is automatically carried out based on time or temperature.
Thisfunction is always active and cannot be switched off.
In Secura
®
models, every adjustment process, including the identified deviations,
isdocumented and saved on the balance. The saved reports can be viewed via the
system settings and printed out on a PC or Sartorius lab printer (see “Calibration/
Adjustment” on page28).
