The UNI-T UT512 insulation resistance meter is a digital meter intended for both electronics enthusiasts and electricians.

It allows the measurement of high resistances up to 100 GOhm with a test voltage of 2500 V.

Some additional features include:

• Dielectric absorption test
• Complexity indicator
• Comparison mode

The insulation resistance measurement levels for various test voltages are:

• 500 V: 0.5 MOhm ~ 5 GOhm
• 1000 V: 2 MOhm ~ 10 GOhm
• 1500 V: 5 MOhm ~ 20 GOhm
• 2500 V: 10 MOhm ~ 100 GOhm

The accuracy is:

• 100 kOhm ~ 10 MOhm ±(3%+5)
• 100 MOhm ~ 10 GOhm ±(5%+5)
• 10 GOhm ~ 100 GOhm ±(10%+5)

It also includes short-circuit current.
