1. Do not rely on autoranging for all tests. Some test steps will require manual ranging.
2. Must allow for source and meter settling before recording reading.
3. Wait at least 60 seconds for source and meter to settle before recording reading.
4. Using Relative Mode (REL) to zero residual reading (apply 0 Ω and allow UUT to settle for 45 seconds before
pushing REL).
