To Make dcv:dcv Ratio Measurements
To calculate a ratio, the multimeter measures a dc reference voltage
applied to the Sense terminals and the voltage applied to the Input
terminals.
dc signal voltage
Ratio
dc reference voltage
To enable ratio measurements, use the MEAS menu.
Ratio annunciator is on when
ratio measurements are enabled.
At the Sense terminals, the reference voltage measurement function
is always dc voltage and has a maximum measurable input of
12 Vdc. Autoranging is automatically selected for reference voltage
measurements on the Sense terminals.
The Input LO and Sense LO terminals must have a common reference
and cannot have a voltage difference greater than 2 volts.
The specified measurement range applies only to the signal connected
to the Input terminals. The signal on the Input terminals can be any
dc voltage up to 1000 volts.
