The AEMC 1050 Megohmmeter is a 1000V Digital/Analog Insulation Tester. It is designed to facilitate testing quickly and accurately by incorporating automatic measurement features and user friendly functions. The AEMC 1050 provides test voltage combinations of 50V, 100V, 250V, 500V and 1000V.
Measurements are displayed on a large dual-display LCD with bargraph for quick viewing of changes or trends. Resistance readings are displayed on the larger display, and a smaller display is used for test voltage at the sample, test run times (mm:ss), or alarm set points – all accessible at the press of a button. A family of visual indicators for safety and information also compliments the displays. A bright blue electroluminescent backlight makes for clear readings in dark areas.
The AEMC 1050 1000V Megohmmeter automatically provides the DAR and PI ratios directly on the display. User defined PI time intervals may also be programmed. The user may even select DAR or PI functions before the test, and the megohmmeter will stop at the appropriate time and display the results. Test run times from 1 second to 59 minutes are also directly programmable. The tested sample Capacitance is available at the end of each insulation resistance test. For specific applications and operator or equipment safety, test voltages may be disabled to avoid any errors.
An automatic test inhibitor prevents testing on live circuits above 25V and discharge test voltage may be displayed. A memory feature permits storage, recalling and displaying of resistance values taken at user specified intervals during a test.
The AEMC 1050 1000V Megohmmeter is built into a double insulated field case with a detachable accessory pouch.
