1.3 Putting into operation
1.3.1 Selecting or changing the location
The correct location is crucial to the accuracy of the weighing results!
Major geographical
location changes
The manufacturer adjusts each scale to the local gravity conditions (GEO value). In
the event of major geographical location changes, this setting must be adjusted by a
service technician. Certified scales must also be recertified observing the national cer-
tification regulations. These steps are not necessary for scales with an internal cali-
bration weight.
Select a stable, vibration-free and if possible a horizontal location.
The ground must be able to safely bear the weight of the fully loaded scale.
Observe the following environmental conditions:
•No direct sunlight
•No strong drafts
•No excessive temperature fluctuations
Aligning the scale
Only scales that have been aligned precisely horizontally provide accurate weighing
results. The certified scales have a spirit level to simplify alignment.
Turn the adjustable feet of the scale until the spirit level’s air bubble is inside the
inner circle.

Introduction
1.3.2 Connecting the power supply
CAUTION!
Before connecting the scale to the mains, check whether the voltage value printed on
the rating plate corresponds with the local mains voltage.
Never connect the device if the voltage value printed on the rating plate is different
to the local mains voltage.
Plug the mains plug into the socket.
After connection, the device performs a self-test. When the zero display appears,
the device is ready to weigh.
Calibrate the device in order to obtain the greatest possible precision, see
Section 3.3.1.
NotePartially certified scales (scales with first-level certification) must be certified by an
authorised body or by the OHAUS Service.
Call OHAUS Service.
NoteThe battery’s charging capacity can be reduced under continuous mains operation.
To maintain the charging capacity, after a maximum of 4 weeks discharge the bat-
tery completely before recharging it.
Scales with a built-in battery can work independently from the mains for approxi-
mately 30 hours in normal operation. A prerequisite for this is that the background
lighting is switched off and that no peripheral devices are connected.
The device automatically switches to battery operation as soon as the mains supply
is interrupted. When the mains supply is restored, the device automatically switches
back to mains operation.
The battery symbol indicates the present charging level of the battery. 1 segment cor-
responds to approx. 25 % capacity. When the symbol flashes the battery must be
charged (min. 4 hours). The charging period is extended if work is continued during
charging. The battery is protected against overcharging.
