1.7 Safety instructions and conformity
1.7.1 Safety instructions
When the balance is used in environments with increased safety requirements, the relevant
precautions must be taken.
The balance must only be operated with a power adapter and power cable in perfect
conditions.
The balance may only be operated with the power adapter and power cable supplied.
Be sure to hold the plug, not the cable, when disconnecting the device from an electrical
outlet.
If the cable, the power adapter or its cable is damaged, unplug the device immediately
from the electrical outlet and keep it from inadvertent operation.
If safe operation of the balance is not possible, it must be disconnected from the power
supply and secured against unintentional use.
Do not operate the device in an area subject to explosion risks or caustic atmospheres.
Take care when handling with liquids, that no liquid is split into the inside of the balance,
on connections of the device, on the power cable and the power adapter. Should this
although happen, unplug the device immediately from the electrical outlet and keep it from
inadvertent operation. The balance may only be operated again after a re-check made by a
service technician.
The device may only be used for weighing of solid materials, of liquids filled into secure
containers, and for running applications designed especially for the device (e.g. density
determination).
Do not exceed the maximum permissible load of the balance.
When using the balance in combination with other appliances made by the original manufacturers
as well as with appliances produced by other manufacturers, the current regulations for the safe use
of the relevant attachments and their application in accordance with instructions must always be
observed.
DANGER
Before connecting the device to the mains, be sure thet the operating
voltage stated on the device and on the power adapter and power cable
agrees with the local mains voltage. If it doesn't, the equipment must
not be connected to the mains at all!
NOTE
If any damage or injury occurs, liability and responsibility rest with the
user.

balance, so that the allowable ambient conditions and prerequisites are met and maintained:
Place the balance on a solid, firm and vibration-proof, horizontal base.
Protect the balance from direct solar radiation.
Avoid drafts and excessive temperature fluctuations.
Ensure the balance cannot be shaken or knocked over.
NOTE
With difficult conditions (where the balance may be easily shaken or
subject to vibration) the balance can nevertheless provide accurate
results through suitable adjustment of the stability control, see 2.2.
2.2 Stability control
For setting all different weighing parameters:
Swipe left for switching the applications screen,
Call up "Settings",
Call up "Weighing parameters", and
Set all parameters upon your requirements.
NOTE
Pressing "?" calls up the contextual Help which provides detailled
information about the point you currently are. For quitting Help, press
"Close".

390 Basics
Precisa Gravimetrics AG 16
2.3 Turning on the balance
The following safety recommendations must be observed when connecting the balance to the
mains:
DANGER
The balance may only be operated with the power adapter and
power cable supplied.
Before connecting the device to the mains, be sure that the
operating voltage stated on the device and on the power adapter
and power cable agrees with the local mains voltage. If it doesn't,
the equipment must not be connected to the mains at all!
Connect the balance to the mains with the supplied power adapter and power cable.
Turn on the balance by pressing "ON/OFF" on the right side of the terminal for about 2
seconds. The balance starts-up and halts at the user screen.
Select Administrator by calling up "Administrator". The balance starts-up executing the
Weighing application.
NOTE
If users already have be defined the user screen could appear after
starting up
NOTE
In order to get exact measurements, ensure the balance has reached its
operating temperature, see 2.8.

2.4 Levelling
To function properly, the balance must be precisely horizontal. Thatfor it is equipped with an
electronic levelling device which makes appear a visual warning on the display if the balance is
tilted outside the internally stored levelling tolerances. To readjust the levelling
Swipe left for switching the applications screen and Call up "Levelling".
Keep adjusting the levelling feet as instructed by the display, until the bubble is right in the
center of the displayed bubble level.
Press "Home" for returning to the weighing application.

Precisa Gravimetrics AG 18
2.5 Customizing and adjusting the draft shield (models
HF/HA/HE only)
For customizing, the slide glasses can be individually coupled with the draft shield carriage.
The draft shield has been well adjusted in the factory and should work perfectly even after
relocating or dismantling and reassembling the glass slides. Should the draft shield, however
unlikely, jam or not open and close properly, please adjust it as follows.
NOTE
If it should still not open or clamp correctly, contact Precisa Service
2.6 Setting the touchless sensors (TLS) (optional)
Touchless sensors are very helpful. They not only allow you to open and close the draft shield, they
let you perform a lot of other routines without touching the balance, too. Operating the balance by
simple hand gestures is a smart way for avoiding vibrations.
For assigning all different hand gestures to certain functions,
Swipe left for switching the applications screen,
Call up "Settings",
Scroll down and call up "TLS", and
Do all settings upon your requirements.
NOTE
Pressing "?" calls up the contextual Help which provides detailled
information about the point you currently are. For quitting Help, press
"Close".
2.7 Adjusting the balance
Since the earth's gravity is not the same everywhere, each balance must - in accordance with the
underlying physical weighing principle - be adjusted to compensate for the gravity at each location.
This adjustment process must be carried out on initial installation and after each subsequent
relocation. In order to get exact measurements, it is recommended moreover, that the balance
should also be adjusted periodically.
Ensure the balance has reached its operating temperature.
Swipe left for switching the applications screen and
Call up "Adjustment".
