DCV Ratio
The DCV Ratio key enables or disables DCV Ratio measurement. Note that the Auto Zero softkey dis-
appears when you enable DCV Ratio measurements. This is because autozero cannot be disabled during
DCV Ratio.
The ratio is the voltage on the Input terminals divided by the reference voltage. The reference voltage is
the difference of two separate measurements. These measurements are the DC voltages from the HI
Sense terminal to the LO Input terminal and from the LO Sense terminal to the LO Input terminal. These
two measurements must be within the range of ±12 VDC. The reference voltage is always autoranged,
and the range used for both will be based on the larger result of these two measurements.
Configure DCV Ratio measurements as shown:
