jns I do not use the auto position, so this is speculation. The manual says: "Only when the voltage is higher than 0.8V, this data will be shown on the display." The meter may be using a little circuit power when it is determining which measurement and range to use. This would be seen as less than tens of megohms of resistance at the leads and would be parallel to what you are testing. Thus some reduction of the voltage reading.
