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.

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.

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.

Calibration/Span Adjustment
Features
Calibration/adjustment can be
performed only when:
– there is no load on the balance/scale,
– the balance/scale is zeroed, and
– the internal signal is stable.
If these conditions are not met, an error
message is displayed.
Calibration is recommended after initial installation and each time the balance/scale
is moved.
The weight required for calibration/
span adjustment is displayed.
Standard calibration weights for selected
models: to remove, see instructions on
page 6.
Press
v to select a different weight
value.
To cancel the procedure: press and hold
the key (> 2 sec.).

Example: Calibrate/adjust span of the balance/scale (here: model ELT 6001)
Step Key (or instruction) Display
1. Switch on the balance/scale e
2. Zero the balance/scale w
3. Start calibration q
The preset calibration weight
is displayed without the weight unit

weight value v repeatedly
5. Confirm calibration weight value and start calibration/span
adjustment
After the zero point is stored, the required
calibration weight flashes on the display.
6. Place the required calibration
weight on the balance/scale
The readout stops flashing if the weight
is applied within the defined time limit and
tolerance. If the weight value is accepted,
the display stops flashing and the stability
symbol appears on the display.
