3. Enter ‘9303yxxx’, replacing the ‘x’s with the desired node number and
the ‘y’ with the system number (usually 0).
4. The scales will restart. Note that the current node number is displayed
during start-up.
5.3 CLEARING THE MEMORY
The memory should be cleared if the controllers batteries have been
allowed to completely discharge for more than 2 weeks.
1. Ensure the scales are in supervisor mode.
2. Press ‘8’ then ‘ENT’.
3. Enter ‘93020246’.
4. The scales will restart.
5.4 STABILITY THRESHOLD AND TIMEOUT
When the controller take a reading of the load on the weigh platform it
actually takes many readings and uses the average. The individual
readings that make up the average are taken continuously. During this
process it also monitors by how much these readings vary.
In most circumstances at the time when the reading is taken the load is
stable and an average reading whose sub-readings are within limits is
instantly available. If the sub-readings vary by more than a preset amount a
message “Acquiring Weight” will be displayed. The controller will then
continue to take sub-readings until either they are within the limit or a preset
time has expired. Both the weight limit (threshold) and the time limit
(timeout) can be set.
A recommended value for the threshold is 0.1% of the load cell capacity
while that for the timeout is 5 seconds.
5.4.1 Threshold
1. Ensure the scales are in supervisor mode.
2. Press ‘8’ then ‘ENT’.
3. Enter ‘93050xxx’ (replace the ‘x’s with the desired threshold in 10g
increments).
4. The scales will restart.
