The meter UT-513A is a specialized device designed to measure insulation
resistance in the range from 0MΩ to 1000GΩ.
Attention! High voltage is required to correctly measure the insulation
resistance value. During the measurement one should be particularly careful and
strictly follow the recommendations included in the device manual.
Resistance measurement:
• Test voltage 500 V : 0.0 MΩ ... 20 GΩ
• Test voltage 1000 V : 0.0 MΩ ... 40 GΩ
• Test voltage 2500 V : 0.0 MΩ ... 100 GΩ
• Test voltage 5000 V : 0.0 MΩ ... 1000 GΩ
Measuring accuracy:
• 0.0 MΩ ... 99.9 MΩ ± (3% + 5)
• 100 MΩ ... 9.99 GΩ ± (5% + 5)
• 10 GΩ ... 99.9 GΩ ± (10% + 5)
• ≥ 100 GΩ ± (20% + 5)
