2. Installation
Your product is a mass weighing instrument and you should take certain cautions during its use.
Before putting your scale to use, it is important to observe the following items:
-Verify that the instrument has not suffered any damage during delivery.
-Check accessories
-Take off protective insulation. (Instruments with dimensions up to 700x700mm)
-Fasten the articulated feet that are in the indicator’s packaging. (Scales 800x800mm
and up, follow the following instructions)
-Adjust the level and then lock the articulated feet using the nuts and bolts if the case
may be.
-The scale cannot undergo any kind of impact or overweighing on the weighing
platform so that there is no damage to the load receptor. Always place cargo as close
to the center of the scale as possible so that there is no lateral force on the load
receptors and so that you get the best weight distribution over the entire scale.
-Do not use the keypad with sharp objects in order to avoid damages to the keypad’s
circuits.
-The cleaning and keeping of the entire scale will also avoid unnecessary
maintenance. When possible, clean the scale with a damp cloth.
-Always clean the scale with the power cord unplugged.
-Always make sure that the scale’s cables and connectors are in perfect condition for
they are essential for proper function.
Maximum performance of your instrument depends on proper installation.
2.1 Choosing an adequate location
The place where the scale is installed must be level. In the case of an uneven surface, compensate
adjusting the leveling or articulated feet that are underneath the base.
Inaccuracies in weighing can be caused by an uneven scale.
Place the scale platform away from strong air currents. (Bench scales)
Place the scale platform away from obstructing objects that my make access to the scale difficult.
