The front panel keys on the 60 Series take on different functions depending
on the selected mode. This chapter will define the front panel key operation
for the Counting Mode.

To activate the counting operation, the indicator must be in the Quantity
mode. To access the Quantity mode on a Model 460, the quantity mode must
be in the selectable modes of instrument operation. Simply press the
[SELECT] key to step through all enabled modes of instrument operation.
The Quantity mode may be accessed directly by pressing [30] [SELECT]
(not available on the Model 460).

Although the sampling process may be performed in a number of ways, the
recommended method is to first access the Quantity mode, then place an
empty box or empty container on the scale platform, and press [ENTER].
The first time a sample is performed, the display will read Must Sampl and
press [ENTER]. The indicator will then perform an auto-tare resulting in a
zero net weight. The display will prompt you to Add xx, where the "xx" is
the sample quantity of parts (sample size)—the manufacturer default setting
is 10 pieces. Add the requested number of parts to the scale and 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. Otherwise, you may
be prompted to add additional parts. The exact prompts will depend on
whether the auto-enhance and/or minimum accuracy assurance features have
been enabled. The minimum amount of weight required for the sample
routine to meet the selected accuracy requirements for the specified scale
capacity is considered.
If the weight of the sample is un-detectable or barely detectable then the
message Code 32 ADD MORE! is displayed briefly. This will most often
occur when the [ENTER] key is pressed without adding any parts. If the
parts were in fact placed on 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 in order to perform the sample.
