Hot-line state detection - Protects Meter on accidental voltage in Part/equipment on Test. (>30V). Large bolt mark - A large (lightning) bolt mark is with a buzzer sound, when HV is applied.
The MIT200 series of insulation and continuity testers are ideal for testing transformers, motors, generators, switchgear, panel building, domestic appliances, power tools etc., as well as fixed electrical wiring systems. - https://megger.com/
Megger - MIT200 Insulation Tester
Insulation testing to 1000 MΩ
Continuity testing at 200 mA down to 0.01 Ω
Live circuit warning (voltage display) and test inhibit
Digital/Analogue display
Alkaline or rechargeable batteries
-10ºC to +55ºC operating temperature
The display offers a combination of digital readout and analog display, using Megger’s patented DART display technology, which includes the benefits of an LCD displa such as robust, clear and accurate measurement, with an analog pointer response for evaluating circuit charge and discharge characteristics.. Continuity testing
Automatic continuity testing is performed at 200 mA to ensure compliance with international requirements. There is no need to press the test button. All instruments will measure up to 100 Ω on continuity, of which 0-10 Ω is performed at greater than 200 mA to meet international electrical testing requirements.
