In order to perform a negative sample routine, access the Quantity mode,
place a full or partially full container of parts on the scale, and press
[ENTER].
The indicator will then perform an auto-tare resulting in a zero net weight.
The display will then prompt you to Add xx where the "xx" is the sample
size. In this case, the prompt Add xx actually means take parts from the
container. Proceed to remove the requested number of parts, and then press
the [ENTER] key. If the sample's total weight was sufficient, the piece
weight will be calculated and the sample quantity will be displayed (-10
parts). Otherwise, you may be prompted to take additional parts. The exact
prompts will depend on whether the auto-enhance and/or minimum accuracy
assurance features have been enabled.
If the weight of the sample removed was un-detectable or barely detectable
then the message Code 32 ADD MORE! is displayed briefly. This indicates
that more weight must be removed adding to the overall sample weight.
This occurs most often when the [ENTER] key is pressed without taking out
any parts. If the parts were in fact taken from the scale, either the parts are
too light to count on that capacity platform or a much larger quantity of parts
must be hand counted out in order to perform the sample.
The first method is recommended to avoid the possibility that inappropriate
tare weights may affect the piece weight calculation.
When the Quantity mode is accessed and the residing piece weight value is
“0.00”, the prompt Must Sampl will be displayed. Press the [ENTER] key
to proceed with the sampling to determine a piece weight.

The presence of this feature depends on the internal setup of your
controller. It is intended for the accurate counting of extremely light parts.
1. Access the quantity mode.
2. Place an empty container on the platform (optional).
