The AEMC 1035 electrical test kit includes a digital megohmmeter plus accessories, for measuring insulation resistance to 20GΩ, low-resistance to 400kΩ, and AC and DC voltage to 600V. In addition to the megohmmeter, the kit comes with a remote test probe, a set of test leads, a set of alligator clips, a test probe, two hook-grip probes, instructions, and a hard carrying case for field testing applications. The remote test probe has a test button for performing measurements and a target light to aid visibility. The auto-ranging meter has four test voltages—50, 100, 250, and 500V—for measuring insulation resistance to indicate the condition of windings or cables in motors, switchgears, electrical and telephone installations, and other insulated equipment. Insulation testing is disabled when a voltage greater than 25V is detected. When measurement is complete and the test button is released, the meter enters voltage detection mode and automatically discharges residual voltage from the circuit under test. High and low thresholds for insulation and resistance measurements can be set, triggering an alarm when readings fall outside the settings, and will be retained even after the meter is powered off. The relative function allows a measurement to be set as a reference value and displays subsequent measurements as a positive or negative deviation from that value. The meter has a 4,000-count LCD with a backlight for visibility in low light that automatically turns off after one minute. The display shows readings numerically and on a 34-segment bar graph. The meter is rated for category (CAT) III installations to 600V, 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 automatically turns off after five minutes of non-use to conserve battery life and has a low-battery indicator that signals when the batteries need to be replaced. 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.
AEMC Instruments manufactures electrical testing and measurement instruments, including clamp meters, power quality analyzers, ground resistance testers, and data loggers. The company, founded in 1893, is headquartered in Foxborough, MA.
