The dimensions of the box have been chosen so that the measured resistivity,- when the box is filled level, can be expressed in ohm-centimeter, which is universally accepted terminology. When used with any MCM multi-combination meter (or separate volt and ammeter) and an external battery, the resistivity of the sample can be calculated as follows:

Resistivity = (change in potential between pins or delta V) / (change in current or delta I)
