displayed. Otherwise, you may be prompted to add more parts. Additional parts are requested if accuracy
minimums are not met. The exact prompts will depend on whether the auto-enhance and/or minimum
accuracy assurance features (Parameter 181 and Parameter 183, respectively) 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 not detectable or barely
detectable then the message “Code 32 ADD MORE!” is displayed briefly. This will most often occur when
you press the [SAMPLE] key without adding any parts. If, in fact, you have placed the parts on the scale,
either the parts are too light to count on that capacity platform or you must hand count a much larger
quantity of parts in order to perform the sample.

Method 1: Counting a specific number of parts
1. Press [SAMPLE] to access the quantity mode.
2. Place the empty container on platform (optional). If a container is not being used, skip this step and
go to step 3. Press the [SAMPLE] key. The Model 672/675 will tare to a zero net weight. The
display shows the current net weight and prompts
3. Place the specified number of parts on the scale. (“Add XX”, “XX” being the number of parts to
sample). The actual number can be programmed by setup parameter P182.
4. Press [SAMPLE] or [F1] to accept the sample. (Or add any number of parts, key in the number
added, then press [SAMPLE].) The piece weight of the sample parts is calculated. If the number of
parts added was insufficient to achieve the required accuracy as set by P183, then “Code 32 ADD
MORE!” is displayed briefly. Add more parts if Code 32 is displayed.
5. Add the additional parts to be counted on the scale.
Method 2: Counting with piece weight enhancement
1. Press [SAMPLE] to access the quantity mode.
2. Place empty container on platform (optional). Press the [SAMPLE] key. The 672/675 will tare to a
zero net weight. The display shows the current net weight and prompts.
3. Place the specified number of parts on the scale. (“Add XX”, “XX” being the number of parts to
sample). The actual number can be programmed by setup parameter P182.
4. Press [SAMPLE] or [F1] to accept the sample.
5. The Model 672/675 calculates the piece weight of the sample parts and momentarily displays the
maximum number of parts that can be added for a piece weight enhancement to occur. Then it
displays the minimum achieved accuracy.
6. If a greater accuracy is desired, add more parts but not more than the maximum enhancing quantity.
7. As soon as motion ceases, the Model 672/675 recalculates the piece weight and briefly displays the
new maximum number of pieces that can be added and still accurately enhance the piece weight.
8. Repeat as many times as desired.
9. Add the additional parts to be counted.
Method 3: Counting with a known container weight
1. Press [SAMPLE] to access the quantity mode.
2. Place the full container of parts on the weigh platform.
3. Press the [SAMPLE] key.
