-Safety instructions and QR code for access to the complete documentation
3.1.5 Leveling the weighing platform
To achieve reproducible weighing results at all times, the weighing platform must be set
up to be precisely horizontal.
Therefore the weighing platform must be re-leveled every time it is moved to a dierent
location.
. Unpack the device and check it for visible external damage.
If there is damage, follow the instructions in the chapter "Safety check".
. Keep the original packaging in case the device needs to be returned. Remove all

Leveling the weighing platform
3.2 Connecting
3.2.1 Connecting the platform
Connection of an analogue Puro® platform or a commercially available strain gauge load
cell to a Puro® indicator.
. Use the adjustable feet to align the weighing platform so that the air bubble of the
level indicator is in the center of the circle.
. Check that all four of the adjustable feet are touching the surface.
The weight of the platform must be spread equally across the adjustable feet.
. Adjust the adjustable feet: Retract the adjustable feet (clockwise) in order to lift the
scale. Extend the adjustable feet (counter-clockwise) in order to lower the scale.
1. Switch o the indicator and disconnect from the electrical supply.
2. Turn over the indicator.
3. Remove the four rubber plugs on the back.
4. Loosen the screws underneath.
5. Remove the cover.
6. Loosen the screw connection.
7. Run the load cell cable through the screw connection.
8. Secure the wires of the load cell cable into the terminals; when doing so, pay
attention to the pin assignments and the color coding of the connection cable for the
platform/load cell.

level of chlorine. Avoid substances with a high or low pH value as otherwise there is
an increased risk of corrosion.
Do not use any abrasive sponges containing iron, steel brushes, or cleaning sponges
made of steel wool.
Always test cleaning agents and materials in non-critical areas rst before using
them.
