The Megabras MD-1000R is a smart, microprocessor-controlled, 1 kV insulation tester for up to 200 GΩ resistance measuring with 250 V, 500 V and 1,000 V test voltage. It is a portable, hand-held, battery-powered equipment. Due to its measurement principle (actual voltage and current readings) it is a "true insulation tester" and so the accuracy of resistance measurement is not affected by any test voltage error.

Operation is very simple and user-friendly: just connect the leads, switch-on the equipment, select the test voltage and press the Test button. Then the equipment automatically selects the most suitable range and shows the measured value in the 3½ digits display.

In order to guarantee the operator safety there are no accessible metallic parts. Output terminals are placed in the furthest and most protected area of the equipment. A light indicator shows high-voltage presence and is switched-off when the capacities (both internal and external) are discharged up to reaching a safe value.

Furthermore, it offers useful additional features: 200 mA continuity range, low resistance measurement, AC/DC voltage measurement up to 600 V, selectable timer, hold memory, and selectable resistance limits for pass-fail testing, with acoustic indication.

Surface leakage paths may affect the measurement of high value insulation resistance. The use of the GUARD terminal permits to remove the effect of this current, substantially improving the test result.

Due to its reduced dimensions and weight, power supply autonomy and mechanical resistance, this equipment is suitable for fieldwork.
