- Range: 1 Micro ohm to 19.999 k ohm in 7 decimal range selectable by selector switch.
- 4½ digit, LED Display, Accuracy ± 0.2% (overall)
- Current – 2 Amps, at lower range(19.999 m ohm) & lower (approx 0.1 A at higher ranges)
- For 10 milli ohm, you will get 10.000 milli – ohm
- Mains Operated. Four Terminal arrangement. Stable Reading
- 'SET ZERO' knob is also provided
- Most suitable to measure resistance of copper wire, aluminum wire having any diameter from 0.1 mm dia to 10mm
- Also suitable to measure resistance of primary & secondary side of potential transformer
An ohm meter can be manufactured by putting fixed resistor, a variable resistor & galvanometer in series with one another. Value of fixed resistance & variable resistances are selected in such a way that current is equal to full scale deflection of the Galvanometer.
