ing the Overload Stop

Note:

Overload stops must be checked following replacement of the strain-gauge
system.

– Open the balance/scale (see page 48) and connect the balance/scale to

power.

- Balances/scales with rectangular weighing pan/load plate: see illustration on

the left (model TE6101 shown in this example).

– Center the required test weight plus approx. 6500 g additional weight

(equal to the weight of the weighing pan/load plate plus shock absorber) on
the weighing pan/load plate.

– Wait until the service software display shows a stable weight readout
– Adjust the stop screw (arrow) outward until the overload limit is just

reached

– The weight readout is no longer stable
– Adjust the stop screw 1/2 turn inward
– The overload stop is now correctly adjusted.
- Balances/scales with a round weighing pan/load plate have two stop screws

(arrows).  Adjust both screws equally.
