Portable megohmmeter 1050

for the aeronautical industry

The Megohmmeter Model 1050 is a 1000V Digital/Analog Insulation Tester. It is designed to facilitate testing by incorporating automatic measurement features and user friendly functions. The True Megohmmeter® Model 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. The Model 1050 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. 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. AC/DC Voltage Measurement Range - 1 to 1000V Accuracy - ±(1% R + 3V) Resolution - 1 to 99.9V: 0.1V 100 to 1000V: 1V Frequency Range - DC and 16 to 65Hz Input Impedance - 750kΩ approx.
