Scale Operation

This section covers the scale operations of simple weighing, counting and hold. The steps for various kinds of weighing are explained in the following pages.
**** A warm-up time of 15 minutes is required to stabilize the measured values.

3.1. Gross Weighing
To perform a gross weighment, follow these steps:

1. Power up the scale. Be sure the scale is displaying weight in the correct unit of measure. Press the UNITS key, if necessary to change the units of measure the scale is working in.
2. Zero the scale if necessary by pressing the ZERO key. If the weight change is within the Zero window area the display will show 0.000. Decimal positions available may vary.
3. Place the item(s) to be weighed on the scale platform.
4. The display will now display the weight of the item that is on the weight platter

3.2. Tare Weighing
If you want to do NET weighing, such as weighing objects in a container, follow these steps:

1. Power up the scale. Be sure the scale is displaying weight in the correct unit of measure. Press the UNITS key, if necessary to change the units of measure the scale is working in.
2. Zero the scale if necessary by pressing the ZERO key. If the weight change is within the Zeroc window area the display will show 0.000. Decimal positions available may vary.
3. Place the item to be tared on the scale platform.
4. Press the TARE key. If the container weight is outside the Zero window area the display will show 0.000 weight and the NET annunciator is illuminated. Decimal positions available may vary.
5. Place the item to be weighed on the scale platform. Net weight of the item is displayed. Press the SELECT key to choose the Gross or Net weight.

3.2.1. Clear a Tare
Remove any load from the scale and press the TARE key until that 0.000 is displayed. Decimal positions available may vary.

3.3. Counting Mode
The ZM110 Counting mode has been designed to allow the operator to easily carry out basic sampling and counting routines on this scale even if the scale is mainly used for general weighing applications. By pressing the UNITS key until Pcs is illuminated on the display, the scale can now be quickly used to sample parts ready for counting.

For count accuracy, all items should be uniform in weight and UF-5 set as HOLD 0. It is recommended that the sample weight be a minimum of 0.1% of scale capacity.
3.3.1. Sampling Parts Prior to Counting
Follow these steps to count items using the sampling method.

1. Power up and if necessary Zero the scale by pressing the ZERO key. If the weight change is within the Zero window area the display will show 0.000. Decimal positions available may vary.
2. Press the UNITS key until 0 Pcs is displayed.
3. Press SELECT to choose the sample size from: 10, 20, 50, 100 and 200.
4. Manually count the sample of parts on to the scale to the agreed sample size and press the PRINT key to confirm.
5. Place the remaining parts onto the scale platform to Count Parts. The display will show the number of parts on the scale.

Follow these steps to perform counting while using a tare:
i. After you have set the piece weight place the empty container on the empty scale and press the TARE key.
ii. The scale will Zero the display and illuminate the Net annunciator. Place the parts to be counted into the container and read off the net count value.

3.4. Checkweighing Mode
Checkweighing is a function that allows the operator to quickly see if a product is within an agreed acceptable tolerance, ideal for fast repetitive work where accuracy is important.
By setting an upper and lower acceptable weight or count limits for a product the scale can be used to check for regular weight or count conformity.
To set the limits and beeper mode, see chapters 3.4.1. and 3.4.2. on page 14.
To perform a gross weighment, follow these steps:

1. Power up the scale. Be sure the scale is displaying weight in the correct unit of measure. Press the UNITS key, if necessary to change the unit of measure.

2. Zero the scale if necessary by pressing the ZERO key. If the weight change is within the Zero window area the display will show 0.000. Decimal positions available may vary.

3. Place the item to be checkweighed on the scale platform.
   The weight is displayed and either the HI, OK or LO annunciator will be illuminated letting the operator quickly see if the item being weighed is within an acceptable weight tolerance to proceed.

4. Remove item from the scale platform and repeat steps 3 and 4 for each item to be checkweighed.

Checkweighing can also be done while using a tare. After you have Zero the scale (step 2), place the item to be tared on the scale, press the TARE key and continue with checkweighing as described in steps 3 and 4.
