Leveling The Device With A Level; Overview Of Calibration And Adjustment; Calibrating And Adjusting Device With Isocal Function (Only Model I-1X) - Sartorius Entris II Essential Line BCE224 Betriebsanleitung

8.3 Leveling the Device with
a Level
Unevenness at the installation site of the device may
result in incorrect weighing results. Leveling balances
out unevenness at the installation site.
Procedure
In order to level the device: Bring the air bubble into
t
the middle of the circular marking. To do so, turn the
leveling feet to the left or right.
8.4 Overview of Calibration and
Adjustment
During calibration, a calibration weight is used to deter-
mine the deviation of the displayed value from the
actual value. The subsequent adjustment eliminates this
deviation.
We recommend regular calibration and adjustment:
− Daily, every time the device is switched on
− After every leveling
− After changing the ambient conditions (temperature,
humidity, or air pressure)
− After setting the device up at a new installation site
8.5 Calibrating and Adjusting
Device with isoCAL Function
(Only Model I-1x)
Triggers for the automatic start of the isoCAL function
are:
− The ambient temperature has changed since the last
adjustment process.
− The interval time was exceeded (interval time, see
Chapter "15.7 Warm-up Time", page 44).
If this relates to a conformity-assessed
model: The device has been disconnected
from the power supply since the last
adjustment.
Requirements
− The automatic or manual start of the isoCal function
is set in the menu (see Chapter "7.2.1 Switching the
isoCAL Function On or Off (Only Model I-1x)",
page 20).
− The device is not located in the menu settings.
− The load on the weighing pan remains unchanged
for 2 minutes.
− The load on the scales amounts to no more than 2%
of the maximum load.
− The device does not register an input for 2 minutes.
Procedure
If the automatic start of the isoCAL function is trig-
t
gered:
The [isoCAL] button flashes in the operating dis-
y
play.
The operating display shows "CAL." for 19 sec-
y
onds.
If no load change or no operation takes place on
y
the device before the expiration of the time dis-
play: The isoCAL function starts.
If the manual start of the isoCAL function is trig-
t
gered:
The [isoCAL] button flashes in the operating dis-
y
play.
Press the [isoCAL] button.
t
The isoCAL function starts.
