The Reference Block Type 2 is used to evaluate the sensitivity of magnetic ink. It consists of 1 steel bar and two permanent magnets on either end. The scale is calibrated such that the +4 mark represents a magnetic field with a strength of +100 A/m and the -4 mark represents -100 A/m. Indication lengths give a measure of magnetic ink performance. Longer indications mean good performance (that of a fresh bath), and they become shorter as the solution performance deteriorates with use.
