(1) The Rogowski coil output is proportional to the rate of change of current. The calculation formula is: Ampere rms x Hertz x K x 10-6, where K depends on manufacturing. The K value is 2 for 100mV models.

(2) RPS50 is delivered with the specified accuracy. Moreover, the calibration of each scale is adjustable by user to achieve the maximum accuracy in conjunction with the coil.

(3) The low limit is approximate and it is determined by noise effect on very low signals.
