Safety Information
§To prevent damage to the equipment,
please read these operating instructions
carefully before using your balance/scale.
!Do not use this equipment in
hazardous areas.
!Make sure the voltage rating printed
on the power supply is identical to your
local line voltage.
!Use only commercially available non-
rechargeable or rechargeable battery:
8+AA, Mignon (not included).
The rechargeable batteries are not
charged when you use the AC adapter.
Please use the charger to recharge the
batteries outside the balance/scale.
– The balance/scale is energized at all
times unless you disconnect the AC
adapter and, if connected, the battery.
– Protect the AC adapter from contact
with liquid
!Exposure to excessive electromagnetic
interference can cause the readout value
to change. Once the disturbance has
ceased, the instrument can be used
again in accordance with its intended
purpose.
Installation
– It is recommended to connect Sartorius
accessories and options, as these are
optimally designed for use with your
balance.
– Do not open the balance/scale housing
as this may void the manufacturer’s
warranty.

!Use only original Sartorius AC adapters:
– for Asia: 400081.1
– for the U.S.: 400314.1
Connecting the Balance/Scale to AC Power
§Insert plug into the jack (located on back of the
balance/scale)
§Plug the AC adapter into an electrical outlet
!LISTED power supply 11 V–21 V compliant with
NEC Class 2 output.
Below-Balance/Scale Weighing
A port for a below-balance/scale weighing hanger
is located on the bottom of the balance/scale.
§Open the cover plate on the bottom of the
balance/scale.
§Attach the sample (e.g., using a suspension wire)
to the hanger.
$Install a shield for protection against drafts if
necessary.
Using a Non-Rechargeable/Rechargeable Battery
(not for model ELT103, GD502)
$A non-rechargeable or rechargeable battery is not
included with the equipment supplied.
!Use only a commercially available non-rechargeable
(8+AA/Mignon) or rechargeable battery.
!When using a rechargeable battery, be sure to
recharge it outside the balance/scale using a sepa-
rate charger.
●Lay the balance/scale on its side
●Lift the compartment cover
●Insert the non-rechargeable (8+AA/Mignon)
or rechargeable batteries into the compartment.
$
Make sure to connect the positive and negative poles
correctly.
●Close the battery compartment: press down on
the cover until it clicks into place.
!All used batteries are classified as waste that requires
special handling (not “household” waste). Dispose
of rechargeable batteries in accordance with the
applicable special waste disposal regulations.

Leveling the Balance/Scale
§Always level the balance/scale again any time after it
has been moved to a different location.
Example: moving bubble from R to L
§Turn the feet as shown in the diagram until the
air bubble is centered within the circle of the level
indicator.
> In most cases this will require several adjustment
steps.
Removing Weights for Calibration/Span
Adjustment
(only for models ELT103, ELT602, ELT402, ELT202,
ELT1001, ELT601, GD502)
§Grasp the tab to turn and pull out the weight
compartment.
$ollow instructions on page 14 for calibration/span
adjustment.

Operation
Basic Weighing Function
Features
– Zeroing the balance/scale
You can zero the balance/scale within
the entire weighing range, up to the
maximum capacity.
Preparation
§Switch on the balance/scale:
press the ekey
§If necessary, zero the balance/scale:
press the wkey
$If necessary, change the configuration
settings: see the chapter entitled
“Configuration”
$If desired, load the factory settings:
see the chapter entitled
“Configuration,” menu item 9.– 1
Additional functions
$Switching off the balance/scale:
press the ekey
