Average = (Meas1 + |Meas2|)/2
1. Connect the 5730A Output HI/LO to the Product Input 2 HI/LO using the
low thermal leads. Connect the 5790B Guard to the 5730A Guard. Ensure
the Guard to Ground strap on the 5730A is installed. Set the Product for
Input 2, External Guard and auto range. Allow three minutes for thermal
dissipation after leads are connected.
