Main Functions
2.4.1
Correction Function
Open clear zero: Eliminate effects of stray impedance on the test side and the instrument.
The instrument can perform single-point, three-point frequency open circuit clear zero or
sweep frequency (all typical frequency) open circuit clear zero.
Short-circuit clear zero: Eliminate effects of series resistance and inductance of the leads.
The instrument can perform single point, thre-point frequency short circuit clear zero or
sweep frequency (all typical frequency) short circuit clear zero.
2.4.2
Comparator Function (Sorting Function)
The instrument can perform multiple sorting, sorting is based on the measured values,
regardless of deviation mode.
PASS file (BIN1-BIN9): indicates that both of primary and secondary parameters are qualified;
Auxiliary file (AUX): indicates that primary parameter is qualified but secondary parameter is
unqualified when the auxiliary file is opened;
FAIL (OUT): The primary parameter is unqualified, or the primary parameter is qualified but
the secondary parameter is unqualified when the auxiliary file is closed.
HI/IN/LO: More detailed comparison results of primary parameters, HI: primary parameters
