1 Compliance

1.1 Compliance with FCC rules

Please note that this equipment generates, uses and can radiate radio frequency energy. This equipment has been tested and has been found to comply with the limits of a Class A computing device pursuant to Sub-part J of Part 15 of FCC rules. These rules are designed to provide reasonable protection against interference when this equipment is operated in a commercial environment. If this unit is operated in a residential area it might cause some interference and under these circumstances the user would be required to take, at his own expense, whatever measures are necessary to eliminate the interference.

(FCC = Federal Communications Commission in the U.S.A.)

HW-G OZIM v1a

2 Outline and Features

The HW-G series is a platform scale with a minimum resolution of 1/10000 .

Type L scales have an LCD (Liquid Crystal Display) and use batteries as a power source to provide portability. This type can also use an AC mains adaptor.

Type V scales have a fluorescent display so the weighing value can be read in dim light. This type uses the AC power line as a power source.

The base unit (platform) is water-resistant in accordance with IP-65 specifications.

The counting mode function converts the total mass value (total weight) of articles to a count, assuming all items to have the same mass.

The percentage mode function displays the mass of an item as a percentage of a stored 100% mass.

The accumulation function accumulates each weighing value and counts the number of weighings.

The comparator function compares the display value with the upper limit value (HI) and the lower limit value (LO) and displays the result. The result can output if option OP-03 is installed.

The simple batch function or full/dribble batch function can be used for filling to a target mass value. The status of a weighing value can be output if option OP-03 or OP-04 is installed. The outputs are Zero Band, Preliminary and Final.

The optional RS-422/RS-485 serial interface can control up to 16 scales from a computer when this option is installed in place of the standard RS-232C serial interface.

Type V scales can be equipped with option OP-06, a built-in impact dot matrix printer.

4 Caution

4.1 Precautions for Installing the Scale

Consider the following conditions to get the most from your scale.

The best operation is where the temperature and relative humidity are stable, the scale is installed on a solid floor or bench and there is no draft.

Do not install the scale in direct sunlight.

Do not install the scale near heaters or air conditioners.

Do not install the scale where there is flammable or corrosive gas present. Do not install the scale near equipment which produces magnetic fields.

Do not install the scale where there is likely to be static electricity discharges in a place where the relative humidity is lower than 45%RH. Plastic and isolators are likely to be charged with static electricity.

The display unit is not water resistant. Use the display unit cover to avoid damage.

Do not use an unstable power source.

4.2 Precautions for Operating the Scale

Periodically check the scale with a known weight.

Calibrate the scale before using it and after moving it to another location.

Do not place anything on the pan which is heavier than the weighing capacity

Do not drop anything onto the pan.

Do not use a sharp instrument such as a pencil or ball-point pen to press the switches. Press the switches gently using only your finger.

We recommend pressing the ZERO or TARE switch before each weighing to prevent possible error.

Replace used dry cells with six new ones when the BATT symbol is displayed. Dry cell (battery) is size D.

4.3 Precautions for Storing the Scale

Do not disassemble the scale.

Do not use solvents to clean the scale.

For best cleaning of the display unit, wipe with a dry lint free cloth or a lint free cloth which is moistened with warm water and a mild detergent.

The base unit can be cleaned with gentle water jets while brushing the base unit.

Weigh only after the unit is dry.

Protect the display unit from dust and water by using the vinyl cover.

Remove batteries from display unit when the scale is not in use for a long time. If you leave the batteries installed they may leak and damage the scale.

5 Installing the Scale

This procedure includes all of the steps for installing the HW-G series scales

Step 1 Unpacking

Remove the weighing pan from the carton and place to one side. Remove the base unit and column from the carton, taking care not to pull on the loadcell cable.

Step 2 Secure the Column

Step 2a Remove the 4 Allen screws from the column lower bracket.

Step 2b Pull the excess loadcell cable through the column as you position the column to the base unit, so as not to damage the loadcell cable. Affix the column to the base unit using four 5mm Allen screws.

Stpe 3 Secure the Display Unit

Step 3a Remove the 2 screws from the rear of the display unit, position the display unit onto the column bracket and pull the excess cable back down the centre of the column to the base unit. Ensure that the cable exits via the cut out in the display unit column bracket and secure the headwork with the 2 screws.

Step 3b Carefully make the connection between the cable connector and J1 inside the headwork, then secure the rear display panel.

Select the place where you intend to instal the scale. Consider “4. Caution” on page 8.

Step 5 Level the Scale

Level the base unit by using the “Bubble spirit level” and “Levelling feet”.

Step 6 Adjust the Display Unit

Press the caps at the pole top from both sides and adjust the angle of the display unit.

Step 7 Connect the Power

Install the batteries (see page 11) or connect the AC adaptor or mains cable. Check the weighing accuracy. If the scale needs calibration, refer to “14 Calibration”.

5.1 Installing the Batteries for Type L

Step 1 If necessary turn off the display and remove the AC adaptor.

Step 2 Press and slide downwards to remove the external cover.

Press the hook of the internal cover to the left side and lift off the cover.

Step 3 Insert six new dry cells ensuring correct polarity (+,-). Battery size is ‘D’.

Step 4 Replace the covers removed in step 2.

Caution

Replace used dry cells with six new ones, when BATT is displayed.

Do not mix used and new batteries. It may cause damage to the battery or product.

Check the polarity when installing the batteries. If you do not observe this it may cause battery leakage. Also if the polarity of a battery is wrong the scale may only work temporarily.

The battery life is dependent upon the environmental temperature. Remove batteries from the display unit when the scale is not to be used for a long time. They may leak and cause damage.

Damage which is due to battery leakage is not covered under warranty.

HW-G Instruction Manual Page 18

7.2 Tare (and Net Display)

The “Tare” is used to cancel the mass of a container, receptacle, case, bag, etc. which is put on the pan to contain the item to be weighed.

Caution

The tare reduces the available weighing range.

The current tare value is reset by pressing the ZERO switch when the pan is empty, or by turning the scale off. (Reset value is zero.)

7.2.1 Semi-Automatic Tare (Input by Weighing)

Step 1 Put the container onto the pan.

Step	2	Press the	TARE	switch. The display becomes zero and the net mark
		is displayed.
Step	3	It is now possible to put something into the container and to read its
		net display.
Step	4	Remove all items from the pan.

7.2.2 Preset Tare (Digital Input of Known Tare)

Step 1		Press and hold the			SET	switch and press the	TARE	switch.
		Then the blank or stored tare value is displayed. This blank display
		means that the tare value is zero (reset value) and						blinks.
Step	2	Set the preset tare value by using the following switches.
		^ switch	selecting the value of a digit.
		< switch	selecting a digit.
Step	3	Press the ENTER switch to store the new preset tare value.
		The scale		a net value i.e. the tare value subtracted from the
