Safety Information
●To prevent damage to the equip-
ment, please read these operating
instructions carefully before using
your balance/scale.
!Do not use this equipment in
hazardous areas.
!Make sure the voltage rating print-
ed on the power supply is identical
to your local line voltage.
!Use only commercially available
9 V batteries (not included).
If desired, you can use a
rechargeable battery.
– 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 electro-
magnetic 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 only
BOECO accessories and options,
as these are optimally designed
for use with your
balance/scale.
– Do not open the balance/scale
housing as this will void the
manufacturer’s warranty.
Symbols
The following symbols are used in
these instructions:

6
Connecting the Balance/Scale
to AC Power
!Use only the AC adapter for
optimal performance and safety.
§Insert plug into the jack (located
on back of 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/Under-ScaleWeighing
A port for a below-balance 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.
Installing the Battery
(not for model BEB43)
$Batteries are not included with the
equipment supplied
!Use only commercially available
9 V batteries.
!If you use a rechargeable battery,
recharge it with an external battery
charger.
§Lay the balance/scale on its side
§Open the battery compartment:
remove the compartment cover
§Install the battery in the compart-
ment
$Make sure the polarity is correct.
§Close the battery compartment:
slide the cover into position until
it snaps into place
!Do not throw away used batteries
with normal household waste.
Rechargeable batteries contain
toxic materials and must be dis-
posed of in accordance with local
waste disposal regulations.

7
Leveling the Balance/Scale
(only for model BEB43)
§Always level the balance/scale again
any time after it has been moved to
a different location.
§Turn the front feet as shown in the
diagram until the air bubble is cen-
tered within the circle of the level
indicator.
§Lower all feet to touch the counter-
top so the balance/scale does not
rock.
> In most cases this will require
several adjustment steps.
RemovingWeights for
Calibration/Span Adjustment
(not for model BEB61)
§Grasp the tab to turn and pull out the
weight compartment.
§Always wear gloves or use tweezers
when handling weights.
$Follow instructions on page 15 for
calibration/span adjustment.
WarmupTime for Model BEB43:
To ensure accurate results, the scale
must warm up for 1 hour before opera-
tion. Only after this time will the scale
have reached the required operating
temperature.

Calibration/Span Adjustment
Features
Calibration/adjustment can be
performed only when:
– there is no load on the balance/scale,
– the scale is zeroed, and
– the internal signal is stable.
If these conditions are not met, an error
message is displayed.
The weight required for calibration/span
adjustment is displayed.
Standard calibration weights for selected
models: to remove, see instructions on
page 7.
Press (F) to select a different weight
value.
To cancel the procedure: press and
hold the (ENTER) key (≥2 sec.).
Example: Calibrate/adjust span of the balance/scale (here: model BEB61)
Step Key (or instruction) Display
1. Switch on the balance/scale (ON/OFF)
2. Zero the balance/scale (ZERO)
3. Start calibration (CAL)
The preset calibration weight
is displayed without the weigh unit
(in this example, 5000 g)
4. To select a different calibration
weight value (F) repeatedly
5. Start calibration/span adjustment (ENTER)
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.
7. Remove the calibration weight
8. Calibration/span adjustment has
been completed
Calibration is recommended after initial installation and each time the
balance/scale is moved.
