The Megohmmeter Model 1030 is a battery powered digital insulation resistance tester. It incorporates the latest measurement technology and is specifically designed to the most recent international insulation and continuity testing standards. The Model 1030 tests at 250 and 500V. It measures insulation resistance, continuity and voltage tests. It incorporates a 600V voltmeter which automatically detects and accurately displays AC/DC voltages in the test circuit on each of the insulation test voltage ranges. Above 25V it also provides an audible and visual signal, and inhibits further tests, thus protecting the user and the meter.
