1. Material: ABS/PVC/Silicone
2. AC voltage: 0V-1000V
3. DC voltage: 0V-750V
4. Capacitance: 0nF-99.99mF
5. Resistance: 0Ω-19.99MΩ
6. Frequency: 9.999Hz-999.9kHz
7. Count: 19999
8. Insulation resistance measurement: connect the test leads, select the voltage range on the dial, press TIME to set the time, press TEST to start, and the test is complete when the triangle indicator light goes out.
9. Polarization index (PI) Measurement: the polarization index is measured because insulation is sensitive to temperature and humidity. Initial measurements are inaccurate due to interference current. Long-term measurement and calculation of this index are necessary to assess insulation quality and aging.
10. Absorption ratio (DAR) Measurement: determines if moisture affects the insulation resistance value of the device by measuring the insulation resistance value after 1 minute and the insulation resistance absorption ratio after 15 seconds.
11. Powered by three 3.7V 14500 batteries, removable and rechargeable with a charger. After fully charging, reinstall the batteries in the meter for recycling and extended battery life (batteries not included in shipment).
12. If the meter remains inactive for approximately 15 minutes, it will automatically shut down and enter sleep mode, saving power and providing peace of mind.

U.S. American Genesis
Format: Kindle
Kindle edition worked well. Very interesting and insightful read by a first rate historian. Tells the story of how our ancestors transitioned from Englishmen to Americans. A book well worth taking the time to read.

History at its best
This comprehensive history of early Virginia persuasively argues that slavery and racism contributed to the American notions of freedom and democracy for those not enslaved. Although first published in 1975, one would never guess that just from reading it. Morgan's argument emerges from such a careful reading and analysis of primary sources that it remains as important today as it was a quarter century ago. The book also provides valuable insights into many subjects other than slavery, including economic and political relations between Virginia and England, early interactions with Native Americans, and changing colonial and British notions of labor and class. Highly recommended on any of these issues.

Fasten your seat belt!
Format: Paperback
The eye-opening journey this non-fiction book offers is not fun, if you are any kind of human being at all. The historical detail and background information is great. The organization makes it easy to understand the complex and entangled events that were happening then and which molded colonial Virginian society, which in turn we inherited. Highest quality scholarship. Dreadful and stomach-turning subject matter. I wish I read this years ago.
