DC:DC Ratio
100mV to 300V
(Input Accuracy) + (Reference Accuracy)
Input Accuracy = accuracy specification for the HI-LO input signal.
Reference Accuracy = accuracy specification for HI-LO reference
input signal (Sense HI-LO input terminals).
NOTE:
Autorange is used for the reference signal regardless of the range set
for the HI-LO input signal. The 10V range is the highest range available
for the reference signal and the highest range the multimeter will
autorange to for measuring the reference signal.
