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 1000 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 megohmmeter" 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 3˝ 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.
DDue to its reduced dimensions and weight, power supply autonomy and mechanical
resistance, this equipment is suitable for fieldwork.
