DCV Ratio
The DCV Ratio key enables or disables DCV Ratio measurement.
Note that the
Auto Zero soft key will disappear when DCV proportional measurement is enabled.
This is because Auto Zero cannot be disabled during DCV Ratio.
This ratio is the ratio of the voltage at the input terminal to the reference voltage. The
reference voltage is the difference between two separate measurements. These
measurements are the DC voltage from the HI sensing terminal to the LO input terminal
and from the LO sensing terminal to the LO input terminal. Both measurements must be
within the ±12 VDC range. The reference voltage is always automatically adjusted, and
the range used for both measurements is based on the larger result of the two
measurements.
Configure DCV Ratio measurements, as shown below:
