Frequently asked questions

What can I adjust with zero/span potentiometers?

Stray current in the measuring circuit causes signal distortion, which can be compensated easily with the ZERO potentiometer at the front of the isolation amplifier. Production tolerances of the shunt resistor can easily be corrected at the percent level using the SPAN-Poti, which means that, for example, an SPS obtains a correct measured value.
