FLINTEC ...the right weigh Calibration of the analogue output 1. Mounting the module The SG module has to be installed in a cabinet in compliance with (inter)national electrical regulations. Connection details are printed on the upper face of the amplifier housing. The amplifier module supports 6 wire technique. If you are using a 4 wire load cell, the “Exc +” and “Sen +” terminals must be shorted together as well as the “Exc –“ and “Sen –“ terminals. 2.
FLINTEC ...the right weigh 4. Output current (or voltage) adjustment Use a digital multimeter with at least a 5 digits display. Connect to current or voltage output as appropriate. Remark: The multimeter should have a current resolution of 0.01 mA to get a calibration accuracy of 0.05%. 5. Setting Zero With no load on the weighing system, use the Zero DIP-switches to initially set the zero value coarsely to approximately 4 mA (or whatever value you want at no load).
