4.3 Weighing System MeasurementMeasure -5 - 35.00mVdcMeasure (0-20.000Vdc)Measure (0-24.000mA)mA--++MEASUREmVSOURCE++++MEASUREmASOURCECALOG+Ex+-mV-mV+Ex-Example: Weighing System MeasurementUsed for measuring loadcell output millivolts from existing operatingsystems. Connect mV measure from CALOG - LC II to loadcell output anddisplay mV. For mass display also measure excitation voltage (on senseterminals) or set a value for excitation with mV/V and units in the mA&masssubmenu. You can then display the loadcell mV as well as the gross masson the loadcell/s (not excluding tare weight). The mA measurement isoptional should you wish to see the mA output from the loadcell transmitter(LCT) whilst measuring mV or mass.Note : mA measure is isolated<strong>Zemic</strong> Europe info@zemic.nl www.zemic.nl8

In the simplest form inject thedesired mV after doing all your own calculations. However, the CALOG - LC II cando mV&mass (enter mV mass) or mass&mV (enter mass & display mV) bymeasuring the excitation (on the sense terminals) or set a value for excitation withmV/V and select units in the submenu.For example: mass&mV, 3 x 1000kg 2mV/V with measured excitation.Select sourcing, submenu select Source: mass&mV , Excitation: measure ,mV/V: 02,00 , Unit: kilogram=kg , Zero value: 00000 , Span value: 03000 ,Dec point: 00000 , mA measure: on .Connect mV leads from CALOG - LC II into the LCT with loadcell mVdisconnected. Connect leads from CALOG - LC II S+ & S- to same on LCT andconnect LCT mA in series through the CALOG - LC II mA measure terminals. Nowby entering a mass value you should get a corresponding value in mA. Adjust theLCT so that 00000kg = 04,000mA and 3000kg = 20,000mA for example.<strong>Zemic</strong> Europe info@zemic.nl www.zemic.nl9
