2.9  Wiring the Circuit under Measurement for 
Direct Input
This section explains how to wire the measurement cable directly from the circuit under measurement 
to the voltage or current input terminal. To prevent electric shock and damage to the instrument, follow 
the warnings given in section 2.5, “Precautions When Wiring the Circuit under Measurement.”
Connecting to the Input Terminals
Voltage Input Terminals
The terminals are safety banana jacks (female) that are 4 mm in diameter.
Only insert a safety terminal whose conductive parts are not exposed into a voltage input terminal.
If you are using the included 758931 Safety Terminal Adapter, see section 2.6.

Current Input Terminals
The terminals are binding posts, and the screws are M6. Either wind a wire around a screw or pass a 
crimped terminal through the screw axis, and then tighten firmly with the terminal knob.
