The microohm meter PCE-MO 3001 is made to measure smallest electrical resistances. It uses four test cables that can be connected to the microohm meter. The microohm meter uses two test cables and a constant current source to allow stable current to flow within the measured device. The other two test cables measure the voltage drop. Due to the fact that this microohm meter is able to measure six different measurement ranges with three different measured currents, the user has the chance to observe a wide range of current. 
The microohm meter is mostly used in those fields where resistance need to be estimated. Because of the measured current which can be set up to 1 A, also the smallest resistances can be measured. The wide LCD and large buttons of this microohm meter allow a comfortable use.
