1. For the 5,000 count mode, divide the number of least significant digits (counts) by 10.
2. For relative humidity greater than 70 %, resistance accuracy is 0.5 % over 1 MΩ and 2.5 % over 10 MΩ.
3. In RF field of 3 V/m, add 45 counts from 470 to 1000 MHz.
4. Using relative mode (REL ∆) to zero residual reading.
