Ohmmeters measure resistance to the flow of current in an electrical component or circuit and check the continuity of an electrical circuit to detect electrical problems such as degraded insulation and improper circuit connections in equipment, wiring, and power supplies.
Ohmmeters have an internal power supply, such as a battery or a capacitor, which supplies current to a circuit or component that is turned off. Test leads are connected in a series to the meter and the circuit or device being tested.
As current flows through the circuit or device, the meter calculates the difference in voltage between the leads and measures the resistance.
The AEMC 6250 Micro-Ohmmeter is a four-input, manual-ranging meter with seven test current/resistance ranges for precise, low-resistance measurements from 0.1 microohm (μΩ) to 2,500 ohms (Ω) of inductive samples such as coils, transformers, and motor windings and resistive samples such as ground bonding, coatings, and contact resistances.leads and measures the resistance.
The AEMC 6250 Micro-Ohmmeter has three test modes: inductive for a continuous test, resistive for an instantaneous test, and auto for multiple instantaneous tests. Four input terminals enable Kelvin-type, four-wire resistance measurements, which are more accurate than two-wire resistance measurements.
