• 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.
• 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.
• 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

Tare Weighing

1. If you want to do NET weighing, such as weighing objects in a container, follow these steps:
2. 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.
3. 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.
4. Place the item to be tared on the scale platform.
5. 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.
6. Place the item to be weighed on the scale platform. The Net weight of the item is displayed. Press the SELECT key to choose the Gross or Net weight.

Example : annunciators lit when tare weighing with 5 kg box and 10 kg of items.

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

Example : annunciators lit when clearing a 5 kg container tare

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.

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 onto 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.

Example : annunciators lit at steps: 1, 2, 3 and 4 when sample size 10 Pcs

Counting can also be done while using a tare following these steps:

•  After you have set the piece weight place the empty container on the empty scale and press the TARE key.
•  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.

Check Counting
Make sure that the unit of measure is PCs and follow the instructions in section 3.4.1, page 14.

Check weighing Mode

1. 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 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 Chapter 3.4.1. and 3.4.2. on page 14. To perform a gross weight, follow these steps:
2. 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.
3. 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.
4. Place the item to be checked weighed on the scale platform. The weight is displayed and either the LO, OK or HI annunciator will be illuminated letting the operator quickly see if the item being weighed is within an acceptable weight tolerance to proceed.
5. Remove item from the scale platform and repeat steps 3 and 4 for each item to be check and weighed.

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

Example : annunciators lit when acceptable limits are: LO < 1.00 kg and HI > 4.00 kg

Hold Mode for Animal Weighing
This function can be used to capture and hold stable weight/pcs values. The indicator temporarily freezes (Hold) the value on the screen for the user to view or record.

To enable the Hold mode, see chapter 3.5.1 To perform a Hold weighment, follow these steps:

1.  Power up the scale and zero the display, if necessary, by pressing the ZERO key. Be sure the scale is displaying weight in your preferred unit of measure. Press the UNIT key, if necessary.
2.  Open the User Menu and select the Hold function [UF-5] to enable the option [Hold 1]. See the instructions below.
3.  Place the item(s)/animal to be weighed/counted on the scale platform.
   • The indicator captures the weight.
   • The indicator freezes the stable weight.
4.  Removing the item(s)/animal from the scale platform will clear the hold weight.
5.  Repeat the steps above for other Hold weighments.

Setting the Hold mode
Open the User Menu and select the Hold function [UF-5] to enable the option [Hold 1]. Settings:

•  PCt is the stability weight window in number of divisions. PCt range = 1 to 100 divs.
•  timE is the number of consecutive weight readings within the stability window to be classed as stable weight. The average of these weight readings is the hold weight that the indicator will display. timE range = 1 to 64.

For example, a smaller PCt value sets a tighter stability window in which the stable weight has to be captured timE number of times.
Valid modes are HOLD 0 and HOLD 1 only. Recommended starting settings: PCt 100 and timE 4. Then adjust to meet the weighing application requirements.

Hold Mode Examples
PCt = 20 divisions, stability window timE =16 weight readings to be taken from within the stability window The hold weight displayed is the last weight reading (H) taken from within the stability window.

Note : a smaller PCt value sets a tighter stability window in which the stable weight has to be captured timE number of times.

• PCt = 20 divisions, stability window time
• E =16 16 weight readings to be taken from within the stability window

The hold weight displayed is the last weight reading (H) taken from within the stability window.
