Page 13: Zero Procedure
7 Zero procedure The ”zero procedure” must be performed at the beginning of the working day and on every hour during the day. This procedure is necessary to account for imperceptible changes in the environmental conditions of the measurements and their compensation. Failure to set to zero may adversely affect measurement accuracy. -
Page 14: Milk Analysis
8 Milk analysis Since Ekomilk Spectra is a hybrid analyzer using infrared technology for adulterant detection and ul- trasonic for standard milk parameters measurement, it can make complex measurements using both modules, or it can be set to only use either the infrared or the ultrasonic module for measurement. So if there is a problem with one of the modules the analyzer can continue working with the other module. -
Page 15: Start Measurement
If there are drops of milk or cleaning solution left in the system, they will fall into the mug. Position of the components: (Figure 11) ˆ place the measuring mug, filled with sample on the Ekomilk Spectra’s working surface ˆ place the empty mug for cleaning solution under the US peristaltic pump Work of ultrasound module: When initiating a measurement, the peristaltic pump on the ultrasound module takes a sample of milk (a yellow arrow, Figure 11), which fills the ultrasonic sensor. - Page 16 A new window pops up asking for the measurement configuration (Figure 13). The main thing here is to select what modules of the hybrid analyzer to be used for the measurement process. To use only the infrared or the ultrasound the check in the corresponding check box must be ticked. To use both infrared and ultrasound simultaneously for complex measurement both check boxes should be marked.

Reports Printer Printers Ekomilk Spectra supports 2 type of printers - internal (Panel EP108PP) and external (Datecs EP50). ˆ Printer mode - manual, auto(printing after every measurement). ˆ Printer parameters - you can choose which parameters you want to print and sort. - Page 22 b) When both devices are connected via cable and adapter it needs to make visible them each other. Easiest way is to make PC as DHCP server with a small program called SmallD- HCPServer.exe (files will be sent separately). Executing that program allows PC set IP (in same subnet) to Spectra.
- Page 23 2. Download measurement result There are few ways to download last data including app, HTTP request, batch scripts, via SFTP. Following text describes some of them. All of them convert necessary data (last measurement) in CSV file format. a) First of methods is with program called getData.exe. After start, enter IP of the Spectra and push GET button - last record will be downloaded in current directory with name last record.csv b) Second method is with HTTP request.

Page 28: Admin Menu
This menu helps us to do the calibration remotely. Use of this menu is rare - for example, when the Ekomilk Spectra is damaged and part of the infrared system needs to be replaced (the cuvette, the glass of the cuvette, measuring board, etc.). - Page 29 But strongly recommend to don’t touch them, unless you are not absolutely sure what you do and reference instrument is really exact. From drop-down menu select for which milk type you want to set correction, then click desired parameter, which you want to correct. A, B and C are constants, used in internal calculations of ultrasound measurement board.

Page 39: Appendix 3 - Troubleshooting
13 Appendix 3 - Troubleshooting 13.1 Filter clogging(infrared only) In case of air bubbles visible in the thin tubing entering the cuvette, the filter on the spout of the infrared module could be clogged (see more section 2). This is often the problem when that happens because the peristaltic pump cannot suck in enough sample and vacuum is created in the system. - Page 40 4. Plug the syringe to the thin tube and gently pull the piston. This creates vacuum that suck any particles that might have been stuck in pockets and acting as valves. Try in the opposite direction if the attempt is not successful. You can repeat this several times, until you manage to unclogging the cuvette minimally to continue with further washing procedures.
- Page 41 In case of impossibility to unclog the cuvette as a last action to resort to the following: 1. Eject the cuvette - see more section 14 (The operation of cuvette ejecting or replacement should be performed by an authorized service or technician) 2.

13.3 Sticking of pump’s silicone hose(infrared and ultrasound) If the Ekomilk Spectra has not been used for a long time or has not been cleaned, the pump hose may become stuck. Signs of this are, for example, if the pump is rotating but cannot suck milk or cleaning solution. - Page 43 7. Once it has blown off you can start assembling it. When replacing the silicone hose, you can gently rotate the pump to make it easier to install. 8. Carefully put the plastic cover on the pump and you will hear it fasten. Then release the outer pump cover and you are ready.
