Yokogawa MY10-01 Analog Insulation Test Meter with Single Rating, 125V/20M OHM, 125mm W x 103mm H x 53mm D

The Yokogawa analog megohmmeter is an insulation tester with a single test voltage for measuring insulation resistance to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures AC voltage and lights an LED to indicate that a circuit is live. When measurement is complete and the test button is released, residual voltage is automatically discharged from the circuit under test. The meter has a battery voltage check that indicates the condition of the batteries. It is rated for category (CAT) III installations, which covers equipment in fixed installations, such as switches in the fixed installation and some industrial equipment that is permanently connected to the fixed installation. It comes with a line probe, an earth probe, a display cover, a shoulder strap, four AA batteries, and instructions. Megohmmeters are commonly used for electrical maintenance and testing in industries such as HVAC, transportation, manufacturing, mining, and utilities, among others.

Megohmmeters, also called insulation testers, are electrical test meters that 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. Resistance is an indicator of the overall condition of the device being tested. Megohmmeters have an internal power supply, such as a battery or a capacitor, which supplies a test voltage to a circuit or component that is turned off. Test leads are connected in a series to the tester and the circuit or device being tested. The meter calculates the difference in voltage between the leads and measures the resistance. Most megohmmeters have two terminals for test lead attachment. The two-terminal, or two-wire, measurement method includes the resistance of the circuit or device being tested and the resistance of the test leads, and generally provides sufficient accuracy for measuring large values of resistance in insulation testing applications.

Yokogawa manufactures test and measurement equipment, navigation systems, and industrial control systems. The company, founded in 1915 in Tokyo, Japan, has U.S. headquarters in Sugar Land, TX. It meets International Organization for Standardization (ISO) standard 9001:2008.
