Measurement principle Name of each parts and buttons (for MO This instrument can measure the earth resistance to earth in multi-earthed system. 1 Transformer jaw Let's regard earth resistance under test as Rx, and the other earth resistances as 2 Trigger , …Rn. - Page 10 By applying the Voltage (V) to the circuit from the Transformer jaw (CT1), current I is (shall be flowed) flowed corresponding to the earth resistance. R can be put out by the calculation after detecting the current with the other Transformer jaw (CT2). In this case, R displayed in this instrument can be regarded as Rx because Rs can be regarded small enough against Rx.
