DO NOT install the balance:
•
Next to open windows or doors causing drafts or
rapid temperature changes.
•
Near air conditioning or heat vents.
•
Near vibrating, rotating or reciprocating equipment.
•
Near magnetic fields or equipment that generates
magnetic fields.
•
On an unlevel work surface.
•
Allow sufficient space around the instrument for
ease of operation and keep away from radiating heat
sources.
2.2 Selecting the Location
The balance should always be used in an environment which is free from excessive air currents, corrosives, vibration,
and temperature or humidity extremes. These factors will affect displayed weight readings.
Wind Shield
On 810g to 8100g balances, a wind shield is provided to
reduce the possibility of air currents from disturbing the
pan. When the wind shield is in place, air currents are
deflected up over the pan. Place the wind shield on top
of the balance making sure the small alignment tab is
located properly on the balance.
2.3 Installing Wind Shield
2.4 Installing Subplatform and Pan
All balances are supplied with a subplatform and pan.
The subplatform fits through the hole on top of the
balance and rests on a cone assembly which is part of
the measuring load cell.
The bottom of the subplatform contains a slotted keyway
for installation purposes. Place the subplatform in place
aligning the slot with the pin on the cone assembly.
Install the pan on the subplatform. The illustration shows
the rectangular pan.
