Grounding (Earthing) Using an Equipotential Bonding
Conductor
§ Connect the scale using a grounding cable
(equipotential bonding conductor not part of the
equipment supplied) to the main grounding
terminal. In addition, the metal housing of the
AC adapter (power supply) is grounded by the
protective grounding conductor of the power
cable. The metal housing of the scale is
connected to the braided shield of the AC
adapter (power supply) connected to the scale.
Warmup Time
To deliver exact results, the scale must warm up for at
least 30 minutes after initial connection to AC power.
Only after this time will the scale have reached the
required operating temperature.
Leveling the Scale
§ Remove the load plate
§ Loosen the locking nuts (1) on all leveling feet
(if necessary, use a 13-mm open-end wrench)
§ Turn the leveling feet until the scale is level.
§ To prevent inadvertent changes to this adjustment,
tighten the locking nuts with a 13-mm open-end
wrench before placing the load plate back on
the scale.
