Calibration/Adjustment - Sartorius Factory Series FC06BBE-S Operating Instructions Manual

Calibration/Adjustment

"isoTEST"
Purpose
Calibration is the determination
of the difference between the weight
readout and the true weight (mass)
of a sample. Calibration does
not entail making any changes within
the scale.
Adjustment is the correction of this
difference between the measured
value displayed and the true
weight (mass) of the sample, or the
reduction of the difference to an
allowable level within maximum
permissible error limits.
Using Verified Scales as Legal
Measuring Instruments in the EU*:
Before using your scale as
a legal measuring instrument, you
must perform "internal calibration"
at the place of installation after
the warmup period.
* including the Signatories of
the Agreement on the European
Economic Area

Available Features
You can start the isoTEST function at
the press of a key to check a scale
used as measuring, inspection and
test equipment at any time. The scale
is calibrated and any deviation is
displayed. Press the
Start
to start adjustment. If you do not wish
to have the scale adjusted, press the
soft key to cancel the isoTEST.
End
Your scale can be calibrated
externally (Scale menu: CAL/isoTST
key function; menu item
Ext.
cal./adj.;factory-def.
or
wt. Ext. cal./adj.;
) or
user-defined wt.
internally (
Internal cal./
).
adjustment
External calibration can
be performed
– using a pre-set weight value
Ext. cal./adj.;
factory-def. wt.
– with a user-defined weight
Ext. cal./adj.;
user-defined wt.
The adjustment can be performed
– automatically following
calibration:
Cal., then
or
auto adjust.
– if desired, the adjustment
operation can be started manual-
ly after calibration:
Cal.,
then manual adjust
You can also configure whether the
calibration mode
– will be activated according
to the specific setting (external/
internal) or
– can be selected by the user after
pressing the
isoTST
.
Selection mode
You can have the scale automatically
display an adjustment prompt after
a certain time interval has elapsed
since the last calibration/adjustment
or when the ambient temperature
changes by a defined amount.
soft key You can also configure the scale
to perform calibration and
adjustment automatically (isoCAL)
when the pre-set time and/or
temperature limit is reached
and reset application
and
On without resetting
.
app
You can have the calibration/
adjustment results documented in
a ISO/GMP-compliant printout;
see page 100.

External Calibration in Verified
Scales of Accuracy Class K
– External calibration is blocked
when the scale is used in legal
metrology
> External calibration can only be
released after removing the
verification control seal, in which
soft key:
case the validity of the
verification becomes void and the
scale must be re-verified
– External calibration can now
be performed
