Light enough to be worn around the neck, they are small enough to be taken into areas which were previously too small to access. DLRO 10 uses a large, bright 4-1/2-digit LED display while DLRO 10X has a large, backlit LCD display.
  • Description

    The Motwane LR 2045-S is a 4 ½ digital micro-ohm-meter, capable of measuring low resistance with 1micro-ohm resolution. It employs the proven 4-wire (4W) measurement where fixed DC current is supplied to DUT and voltage drop across the DUT is measured and displayed as proportional resistance reading. The meter is able to deliver guaranteed stable readings on inductive as well as resistive loads.
