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. 1.
2.0 TROUBLESHOOTING 1. Unit does not turn on 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. . 2. The scale weighs but is unstable Air drafts or vibration or unstable table. Pan rubbing against case or not installed correctly. Scale not installed properly. Improper connections on ADC circuit. 3.
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.
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.
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.
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.
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.
4.3 DETERMINING VALUE OF PRODUCT BY WEIGHT To determine the value of a product sold by weight it is necessary to enter the cost per kilogram using the numeric keys or one of the preset PLU values. The Weight display will show the net weight, the Unit Price display will show the price per kilogram or per 100g as selected by the [kg 100g] key. The Total Price display will show the computed value for the total price.
4.4 USING A STORED PLU VALUE FOR UNIT PRICE The user can store and recall up to 43 PLU values (Product Look Up). The values stored are used to calculate the price for goods. The value is stored as either cost per kilogram or cost per 100g. The keys labelled [PLU1] to [PLU3] are used to immediately recall the most used PLU values and the [PLU4] key is used to access up to 40 other values. To recall one of these values the following procedure applies. 1. 2. 3. To recall PLU number 1, simply press [PLU1].
4.5 ENTERING VALUES FOR THE PLU s To store values into the memory for the PLU s follow the procedure. Entering values for PLU1 to PLU3 keys Enter the unit price value using the keypad, selecting either price/kg or price/100g if needed. Press and hold down the key [PLU1], [PLU2] or [PLU3] for more than 3 seconds. The scale displays “PLU” “ 1” ”SAVEd” Entering values for the [PLU4] key Enter the unit price value using the keypad, selecting either price/kg or price/100g if needed.
4.7 Kg/100g KEY, PRICE PER KILOGRAM, PRICE PER 100g The [kg 100g] key will change the scale from using a price per kilogram to price per 100g. It will also change the arrows under the Unit Price display to show the selection. This information is also saved for the PLU values that are stored in the memory. NOTE: This is not applicable for AZplus for South Africa and Far East. The current software revision number is 1.61. For all revisions from 1.
4.9 BACKLIGHT OPERATION The backlight may be enabled or disabled by the user. If the backlight is disabled battery life will be maximised. With the backlight in operation the battery life will be less, depending upon the extent at which the scale has been used. To enable the backlight Press and hold the [Auto Clear] key for 4 seconds. Press the [PLU4] key to change the operation: “EL” “ “EL” “ “EL” “ AU” on” oFF” Automatic control of the backlight Backlight on full time Backlight turned off.
5.0 CALIBRATION 5.1 CALIBRATION PROCEDURE The scales are sealed to prevent unauthorised calibration. Contact Adam Equipment or your supplier for more details. The calibration of the AZplus scale is accomplished by removing the label at the base of the scale which covers a hole through which the PCB can be accessed. If your scale is not provided with this hole, you need to break the security seals and remove the top cover to gain access to the circuit boards inside.
5.3 CALIBRATION PROCEDURE The scales are sealed to prevent unauthorised calibration. To calibrate the scales, access to the PCB inside is needed to place a jumper in K6 position. This is done by removing the tamper-proof label placed on a hole at the bottom of the scale. Through the hole, pick up the jumper (the jumper will be there placed on one of the pins on the PCB) and place it in the desired K6 position.
6.2 USING “2003” TO ENTER THE SERVICE PARAMETERS After the jumper has been placed in position K6, apply power to the scale. During the self-test press the [Tare] key. The display will ask for a code number, “Pn - - - -“ on the Weight Display. Enter the number 2003 when “Pn - - - -“ is displayed and then press [Tare]. The displays will show the first parameters, called “F1”. To select another parameter press the [PLU4] key to advance through the parameters. Press the [Tare] key to enter a parameter.
6.2.1 F1 -CALIBRATION To enter the calibration parameter, press the [Tare] key when “F1” is displayed. The display will instruct you to remove any weight from the scale, “UnloAd” The display will tell you to add weight to the scale: “LoAd” “ 15” “kilo” Add the weight shown, wait for stability then press the [Tare] key. The display will show “SPAn” “PASS” if the calibration is OK. Or it will show “SPAn” “FAIL” if calibration could not be completed correctly. The scale will return to the parameter menu. 6.
NOTE: The scale must be originally built for the capacity selected. The 6 kg unit uses 10kg load cells, the 15 kilogram unit uses 20 kilogram load cells and the 30 kilogram unit uses 35 kilogram load cells. 6.2.4 F4 WEIGHT DECIMAL POINT POSITION To enter this parameter, press the [Tare] key when “F4” is shown. The display will show the current decimal point location in the Weight window. Press the [PLU4] key to change the value and press [Tare] to accept the value.
6.2.6 F6 -INITIAL ZERO RANGE To enter this parameter, press the [Tare] key when “F6” is shown. The display will show the current initial zero range. Press the [PLU4] key to change the value and press [Tare] to accept the value. NOTE: Only 10% is allowed for the AZplus scales. 6.2.7 F7 -RE-ZERO RANGE To enter this parameter, press the [Tare] key when “F7” is shown. The display will show the current re-zero range. Press the [PLU4] key to change the value and press [Tare] to accept the value.
6.2.9 F9 -A/D COUNT To enter this parameter, press the [Tare] key when “F9” is shown. This parameter allows you to view the A/D counts from the internal A/D converter. This can be an aid to service. Press the [Tare] key to return to the PARAMETER menu. Press the [Zero] key to return to weighing. Ranges allotted at zero is 30,000-90,000 (approx.) Ranges allotted at full capacity is 400,000 (approx.
