UEi DMEG3/IRT3, Инструкция по эксплуатации

Страница: 3 / 34

Introduction
Your UEi Megohmeter allows you to predict, prevent and
identify insulation failures that can cause appliance failure, stop
production, create power problems and even put lives at risk. It
quickly tests insulation integrity on motors, power distribution
systems and other installed wiring.
All insulation has a limited life span and environmental factors
such as heat, cold and airborne chemicals can rapidly decrease
an insulating material’s predicted life. Use this instrument to
help you quickly and safely determine your insulation’s integrity.
Features include
• Large digital display that shows the test function along
with the measured value on the DMEG3 or a high-contrast
analog display on the IRT3
• AC Voltage measurement to 600 Volts
• Insulation resistance readings from 0 to 2000 Megohms
with the DMEG3 or 200 Megohms with the IRT3
• Three test-voltage ranges (250, 500, 1000 V DC)
• Live circuit (external voltage applied) warning light
• Fuse protected against accidental misuse
• Precision resistance measurement to 0.01 ohms with
audible continuity (DMEG3 only)
• 200 mA short-circuit continuity test current for high
accuracy (DMEG3 only)
• Precision, low resistance test leads
(1000 Volt CAT III rated)
• Audible continuity (DMEG3 only)
• Green LED power-on indicator (DMEG3 only)
• Low battery indication/detection
• Maintains rated voltage on cables with up to
1 mA leak-rate
• Automatic, post-test cable discharge
• Rugged, compact case with latching cover to keep
the elements out
