- Page 12 NEW ROYAL 02 TECHNICAL SPECIFICATIONS 2.3. Specification for the measurement of the coffee products temperature. The temperature is influenced by the flow from the dispenser and stratification of temperatures in the glass. In order to consider these phenomena and to introduce measures that allow comparisons in controlled conditions, below guidelines must be followed: Conditions: a) Water temperature in tank: 23°C (+/-2°C). b) It must be used a plastic cup (see picture N°1). c) It must be used a thermocouple thermometer (e.g. type K - see picture N°2). d) The coffee machine is tested without any change of parameters or calibrations, which may affect the temperature of products, so the measurement of temperature must be done with machine in default factory setting. Procedure: 1. The temperature must be measured in the cup, immediately after dispensing. Cup has to be placed on a non-metal surface using a thermocouple thermometer (Picture 1).

Page 13: Specification For The Measurement Of The Milk Products Temperature
NEW ROYAL 02 TECHNICAL SPECIFICATIONS 2.3.1. Specification for the measurement of the Milk products temperature. Milk evaluation To carry out the test, a partially skimmed UHT milk with a percentage of grease between 1.5-1.8% at a refrigerator temperature Trefr. (between 4 to 10°C) must be used. The milk product must be checked on a beaker of 250 ml of capability and with an inner diameter of 70mm, brewing 100gr of product. Parameters to be respected: The parameters to be respected are: milk temperature and height of the cream. Each of these pa- rameters, however, must be evaluated depending on the type of system used for the production of hot milk. - Page 14 NEW ROYAL 02 TECHNICAL SPECIFICATIONS How to measure the milk cream. The temperature (Trefr or Tamb) of the milk doesn’t affect as much the test result on measuring the milk cream; by convection is assumed to always use milk at refrigerator temperature Trefr.. Manual systems (Pannarello) Pour 100cc. of milk at Trefr. in a beaker of 250 ml of capacity and with a inner diameter of 70 mm; with machine in steam mode: 1. Open the steam knob to discharger water circuit for 4 sec, then close the knob. 2. Place the beaker with the frother dipped in milk, open the steam knob to maximum and start the chronometer. 3.
