Abstract

The ohmmeter has an electronic switch and cut-out pulse former, with d.c. current source output via a switch to current chopper whose outputs are linked to the first and second terminals of the device. The third terminal is connected via the electronic switch to the sync. detector input, whose control inputs are linked to the control inputs of the cut-out pulse former and the corresp. chopper outputs. - The voltage, proportional to the measured resistance, from the potential electrode (16) of the earthing device (6) goes to the input terminals (15,14) (when measuring the earthing resistance, terminal 14 is connected to terminal 4).
