ஹ்ம்ம்,

hmm's Usage Examples:

In the Nalder ohmmeter the electrostatic principle is employed.

In this case the dynamo and ohmmeter are combined in one instrument.

Niall hmm, a ' penetration testing ' firm has worked out a way of pumping smut into every room.

An ohmmeter in one form consists of two pairs of coils, one pair called the series coil and the other called the shunt coil.

Connect the ohmmeter across the contacts of the switch and actuate the switch's arm several times while checking the meter reading.

Suppose it is desired to measure the insulation-resistance of a system of electric house wiring; the ohmmeter circuits are then joined up as shown in fig.

In making the test, the whole of the copper wires belonging to any section of the wiring and the test must be connected together at some point and then connected through the series coil of the ohmmeter with one terminal of the dynamo.

For this purpose the ohmmeter is provided with a small dynamo D, contained in a box, which produces a continuous electromotive force of from 200 to 500 volts when the handle of the instrument is steadily turned.

v), but when the resistance of the conductor to be measured is several hundred thousand ohms, or if it is the resistance of a so-called insulator, such as the insulating covering of the copper wires employed for distributing electric current in houses and buildings for electric lighting, then the ohmmeter is more convenient.

Electricity (hmm, I guess the trailer was solar powered), a refrigerator, air conditioning.

ohmmeter check will verify an open field coil.
