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. 1.1 FEATURES: Stainless steel

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. Example: Display will show Weight in kg. Unit Price Total Pri

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. To recall PLU numbe

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. If the hole is not provided in your scale, the security seal has to be
