1.0 INTRODUCTION

The AZplus series of digital price-computing scales provide an accurate, fast and versatile method of computing price by weight.

These series of scales are EC approved for the use in UK and Europe.

For all revisions from 1.27 and above, the Price per kilogram and per 100 gram [Kg 100g] key can be disabled at the factory for the scales to be used in South Africa and Far East. This is done by linking the jumper at K5 position on the PCB.

turn on

2. The scale

weighs but is unstable

3. Scale shows

Check whether the scale is plugged into the power supply properly.

Check the operation of the charging circuit.

Check whether the battery is charged- LED should turn to green from red.

Check the adapter output. . Air drafts or vibration or unstable table.

Pan rubbing against case or not installed correctly.

Scale not installed properly.

Improper connections on ADC circuit.

Scale not installed correctly.

wrong weight

4. An error “E4”

displays on the screen

Check the Calibration.

To check whether a part of product weighed is trapped between the pan and the scale.

Incorrect adjustment of the mechanical stops.

Load cell damage.

Scale not installed properly.

Incorrect adjustment of the mechanical stops.

Factory calibration has been tampered with- check the ADC counts and re-calibrate.

5. An error “E9”

The scale is not stable to set the initial zero. displays on the screen

3.0 INSTALLATION

3.1 GENERAL INSTALLATION

The scales should not be placed in a location that will reduce the accuracy.

Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents.

Avoid unsuitable tables. The table or floor must be rigid and not vibrate.

Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors.

Do not place near vibrating machinery.

Avoid high humidity that might cause condensation. Avoid direct contact with water. Do not spray or immerse the scales in water.

Avoid air movement such as from fans or opening doors. Do not place near open windows or air-conditioning vents.

Keep the scales clean. Do not stack material on the scales when they are not in use.

3.2 PREPARATION FOR USE

The scales come with a stainless steel platform, packed separately.

Place the platform in the receptacles on the top cover.

Do not press with excessive force as that could damage the load cell inside.

If an optional scoop has been supplied, place it on top of the platform.

If an optional display on Pillar is supplied, install the pillar in the upright position into the socket at the rear of the scale by carefully pushing the cable inside the pillar rod. Secure the pillar rod to the socket by using two M4 screws. A black plastic cap is provided to seal

the socket from the bottom to avoid damaging of the cable.

Level the scale by adjusting the four feet. The scale should be adjusted such that the bubble in the spirit level is in the centre of the level and the scale is supported by all four feet.

Turn the power ON using the switch located on the right side of the base.

The unit will display the software revision number in the Weight window and count down to zero while performing a self-test.

When ready all three displays will show zero.

Level the scale by adjusting the four feet. The scale should be adjusted such that the bubble in the spirit level is in the centre of the level and the scale is supported by all four feet.

Turn the power ON using the switch located on the right side of the base.

The unit will count down while performing a self-test.

When ready the displays will show zero.

3.3 DISPLAY WINDOWS

Not applicable for South Africa and Far East

The window for the Weight has arrows to indicate when the scale is at zero or if the scale is displaying a net weight (if a tare value has been entered). It also indicates when the scale is stable.

The window for the Unit Price has arrows to show when the Auto Clear function is active and whether it displays the price per 100g or per kilogram.

NOTE: For AZplus for South Africa and Far East, unit weight per 100g or per kg is not available.

The window for the Total Price displays the price of the items on the scale. Below this window is a LED to show the state of the battery charger.

The above display panel is also available with French, German, Spanish, Dutch

and Italian text or with symbols for Weight, Unit Price and Total Price.

3.4 BATTERY CHARGING

The scale has an internal rechargeable lead acid battery. This battery will make the scale operate for more than 70 hours when fully charged or less if the backlight is on.

When the battery needs charging the arrow above the low battery symbol under the Weight display will be on. The battery should be charged immediately. The scale will still operate for about 10 hours after which it will automatically switch off to protect the battery from getting damaged.

To charge the battery, simply switch the main power ON. The scale does not need to be turned on.

The battery should be charged for 12 hours for full capacity.

Just under the Total Price display is an LED to indicate the status of battery charging. When the scale is plugged into the main power, the internal battery will be charged. If the LED is green the battery is fully charged. If it is red the battery is nearly discharged and yellow indicates the battery should be charged longer, preferably overnight.

3.5 KEY DESCRIPTIONS

Not applicable for South Africa and Far East

Note: The AZplus scales sold in Europe have a slightly different keypad. For Tare and Zero, the text keys are replaced by the symbol keys.

[., 0-9] keys

Numeric entry keys to set the unit price. Pressing [.] will display the price with “00” added after the digit.

[CE] key Used to clear an erroneous entry or return to normal operation.

[PLU1] to [PLU4] Used to store or recall one of the PLU values. [PLU1] to [PLU3] are immediately used, [PLU4] will also select one of the 39 additional values.

[Tare] key It tares the scale to display zero weight when an empty container is placed on the platform or removed again.

[Zero] key It sets the zero of the scale when the platform is empty and no tare value is entered.

[Auto Clear]

It enables the user to automatically reset the unit price to zero, when the weight is removed.

[Kg 100g]

It selects the unit price per 100g or per kilogram.

NOTE: For AZplus for South Africa and Far East, this selection of unit price per 100g

or per kilogram is not applicable.

4.0 OPERATION

4.1 ZEROING THE DISPLAY

You can press the [Zero] key when no tare is entered to set the zero point from which all other weighing is measured. This will usually be necessary when the platform is empty.

When the zero point is obtained the Weight display will show an arrow next to the Zero legend marked under the Weight display.

The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the platform. However you may need to press the [Zero] key to re-zero the scale if small amounts of weight are shown when the platform is empty.

4.2 TARING

Taring is used to eliminate the weight of a container so that only the net weight is displayed.

Zero the scale by pressing [Zero] if necessary. The zero indicator will be on.

Place an empty container on the platform. It’s weight will be displayed.

Press [Tare] to zero the scale. The weight that was displayed is stored as the tare value and that value is subtracted from the display, leaving zero on the display. The Net indicator will be on. As product is added only the weight of the product will be shown.

When the product and container are removed the weight display will show a negative value. If a different container is to be used, remove this negative tare value by pressing the

[Tare] once more.
