Hi,
I would like to be able to measure very low resistances RELIABLY and with some degree of PRECISION.
Measurements of interest would be (for diagnosis):
a) Glow plugs (typical resistance 0,2 ohm)
b) Contact resistance on for instance ground cables (from battery to chassis, to engine, back to chassis etc etc). I would like to measure where there is a bad contact due to corrosion which will result in a voltage drop.
I have the possibility to buy a special multimeter designed for measuring low resistances more precisely. That multimeter applies 0,2 Amps when measuring resistances and should be considerably more than a standard multimeter.
Can anyone elaborate on whether 0,2 Amps is sufficient for measuring low resistances and thus voltage drops for automotive use?
