AEMC Model 1026 Megohmmeter
The Megohmmeter Model 1026 is a compact, lightweight, battery-operated, hand-held meter. It provides four functional tests. It is a megohmmeter, DC voltmeter, AC voltmeter, ohmmeter and a continuity tester. The Model 1026 tests at 250V, 500V and 1000V and measures insulation resistance from 1kΩ to 4000MΩ.The Model 1026 also features a continuity test range with audible beeper for resistances under 40Ω, and a 600VAC range for safety voltage check. In addition, the Model 1026 has an ohmmeter to measure from 0.1Ω to 4000Ω.The Model 1026 is supplied with test leads, clips, batteries, soft carrying case and a user manual.
