Digital megohmmeter has five test voltages-50, 100, 250, 500, and 1,000V-for measuring insulation resistance to 4,000 gigaohms, and also measures low-resistance to 400 kilohms and capacitance to 5 microfarads
Measures voltage to 1,000V and disables insulation testing when a voltage greater than 25V is detected
Calculates and displays DAR and PI for a detailed indication of insulation condition
High and low thresholds for insulation and resistance measurements can be set, triggering an alarm when readings fall outside the settings
Meets EN safety standard 61010-1 and 61557 and is rated for CAT III installations to 600V
About AEMC 1050 Digital
The AEMC 1050 digital megohmmeter is an auto-ranging insulation tester with a voltage safety check and five test voltages—50, 100, 250, 500, and 1,000V—for measuring insulation resistance to 4,000GΩ to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures low-resistance to 400kΩ, capacitance to 5μF, and AC and DC voltage to 1,000V, disabling insulation testing when a voltage greater than 25V is detected. The R-DAR-PI (resistance-dielectric absorption rate-polarization index) function calculates and displays the DAR and the PI, which are measurements over time that give a truer indication of insulation condition than single-point measurements. The timer function allows timed testing from 1 to 59 minutes. 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. When measurement is complete, the meter enters voltage detection mode and automatically discharges residual voltage from the circuit under test. A memory function allows storage and recall of 20 readings. The meter can perform a continuity check up to 40Ω and buzzes to confirm that a circuit conducts electricity. Built into a double-insulated, dual-walled field case, the meter has a 4,000-count LCD with a backlight for visibility in low light. The display shows readings numerically and on a 31-segment bar graph. Megohmmeters are commonly used for electrical maintenance and testing in industries such as HVAC, transportation, manufacturing, mining, and utilities, among others.This auto-ranging meter automatically selects the appropriate operating range for measurements. It is rated for category (CAT) III installations up to 600V, which covers energy-consuming equipment connected to a fixed installation, including household, office, and laboratory applian
