The AEMC 1050 Megohmmeter 1000V Resistance Tester 2130.01 tests at 1000V, 500V, 250V, 100V, and 50V. All measurements are displayed on an extra-large dual LCD with a live bar graph which helps display trends and changes. DAR and PI ratios are directly displayed. PI time intervals can be programmed by the user. User may select PI or DAR functions before the test, and the Megohmmeter will stop at the appropriate time with displayed results. Automatic safety measure prevents the user from testing on circuits above 25V. A discharge test voltage may be displayed during this measure. Resistance values at user specified intervals can be recalled via memory feature.
