Table 3-21: Data output format for RLC value, delta%, deltaRLC, or RATIO
* Underrange generally occurs when the measured impedance is lower than the nominal low limit (for automatic range change)
and there is a lower-impedance range. Overrange generally occurs when the measured impedance is higher than the nominal
high limit (for automatic range change) and there is a higher-impedance range. In either case, an appropriate range change
will improve accuracy. If there is no appropriate range to change to, the status is "range end ex tension "; see below. Range
limits are different if CONSTANT VOLTAGE OR CONSTANT CURRENT has been selected; see paragraph 3.5.6.
** Range 1 end extension if DUT impedance exceeds that of the largest R or L (smallest 0) in basic range 1. Range 4 end
extension if DUT impedance is less than that of the smallest R or L (largest 0) in basic range 4. No possibility of changing range
to improve accuracy.
*** If the measurement is outside of the display range (display goes blank), 9999999 is output in this numeric field.
