AEMC 1050 2130.01 1000V Digital Megohmmeter Insulation Resistance Tester

The AEMC 1050 1000V Megohmmeter is a Digital - Analog Insulation Tester that is designed to facilitate testing by incorporating user friendly functions and automatic measurement features.


The 1050 delivers test voltage combinations of 50, 100, 250, 500 and 1000 Volts. Measurements are displayed on a large LCD dual display with bargraph for quick viewing of trends, changes, PI and DAR ratios. User defined PI time intervals may also be programmed, the user may select PI or DAR functions before the test, and the megohmmeter will stop at the appropriate time and display the results. An automatic test inhibitor prevents testing on live circuits above 25 Volts and discharge test voltage may be displayed. A memory feature permits displaying, recalling, and storage of resistance values taken at user specified intervals during a test.
