individual element output adjustment is available for 3 phase, 4 wire. (Note that the current cir by adjusting the trimmers through holes near ter cuit connected to terminals #13 and #14 of the 4 minals #6 and #10. These should not be adjusted wire unit must be connected with reverse polarity in comparison to the other current circuits to unless a complete re-calibration procedure can be... - Page 5 I.L. 43-846.1A Troubleshoot the switching circuit of the in CURRENT SUMMING operative element. Any number of transducers may be totalized by calibrating each unit as required for correct NO OUTPUT scaling and connecting all the outputs in parallel.
