Hi Jackbauer. As harlequin2 mentioned, both Tamura and LEM have a 2.5V quiescent output which the op-amp would null out. The remaining difference would be that of gain. Full range positive output for both devices is 4.375V which is 500A for Tamura and 900A for LEM hass 300. You would need to multiply the bAmp value in software by 1.8. The subroutine "fracmult" would let you get close by doing a multiply of 1.8125 (mult by 29 followed by divide of 16). 500 amps would read as 504 but if that's good enough you could use that.
