Disconnect the multimeter probes avometra or from any external circuits.Plug the black probe connected to a common socket tester, and red or white (depending on model) - jack for measuring the resistance on the rough edge.
Explorer, whose integrity should be checked on both sides disconnect from any external circuits.If checked multicore cable, this applies to all its member conductors .
multimeter with switch to select the most brutal of the limits of resistance measurement.If you have a sound mode switch is its continuity.
Connect probes muyudu themselves.At the switch avometra pointer must deviate to about the last division, while the DMM on the indicator should appear zeros (echoing the num
bers 1 or 2 LSB).If the mode of the sound continuity, hear a squeak.
have dial tester, without opening the probe, the regulator set the arrow exactly to the last division of the scale (mode ohmmeter it - the first).
Open the probes, and then connect them to the wire.If it is intact, the instrument will show zero resistance.
have stranded cable conductors which do not differ from each other by the color of insulation, using a tester or multimeter to locate the start and end points of each of the cores.Label them pieces of colored tape.It is worth to check the cable for a short between the conductors.If the operation of the cable is such that threaten circuit malfunction or fire, this check is required at all.
Disconnect the device from the cable.Himself cable is connected to the device circuits, as part of which it will be used.Do not confuse it with the guides.Multimeter tester or switch to a mode in which the battery from its energy not consumed.
