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

8.3 Leveling the Device with a
Level Indicator
Unevenness at the installation site of the device may
result in incorrect weighing results. Leveling balances
out unevenness at the installation site.
Procedure
1
To level the device: Bring the air bubble of the
t
level indicator into the middle of the circular
marking. To do so, turn the leveling feet to the left
or right.
Check that the device is standing on 4 leveling
t
feet and the support foot (1) is not in contact with
the setup surface.
8.4 Overview of Calibration and
Adjustment
During calibration, a calibration weight is used to
determine 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
Unscrew the rear level-
t
ing feet, until they touch
the setup surface.
The support foot (1) is
y
not in contact with the
setup surface.
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
Kapitel „15.7 Warm-up Time", Seite 43).
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 Kapitel „7.2.1 Switching the
isoCAL Function On or Off (Only Model I-1x)",
Seite 18).
— 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
t
triggered:
The [isoCAL] button flashes in the operating
y
display.
The operating display shows "CAL." for 19
y
seconds.
If no load change or no operation takes place on
y
the device before the expiration of the time
display: The isoCAL function starts.
If the manual start of the isoCAL function is
t
triggered:
The [isoCAL] button flashes in the operating
y
display.
Press the [isoCAL] button.
