After selecting the parameter to Ls-DCR, press
PARA A
again to turn off the
AC test and enter into the DCR independent test status.
5.6.5 Leakage inductance L
k
Leakage inductance is not the direct measurement parameter of
STB8827
A
. According to the definition of the transformer leakage inductance, Ls with
LCR function can simply test the leakage inductance, as shown in figure 5-20.
As for the test line, TH26011 can be used.
Figure 5-20 Leakage inductance measurement of transformer
In transformer measurement mode, disconnect Hcur terminal and connect
with the secondary polarity in short circuit, primary L
k
can be measured with L2A;
disconnect Hpot terminal and connect with the primary polarity in short circuit,
secondary L
k
can be measured with L2B.
5.6.6 Winding capacitance Co
The equivalent capacitance of transformer winding can be measured with Cp
parameter in LCR manner.

As for the test line, TH26011 can be used.
5.7 Setup example of comparator
STB8827
A provides complete comparator function. It is convenient
for component measurement and judgment, incoming and outgoing
quality inspection in production line. Standard configuration of HANDLER
interface makes it realize automatic sorting measurement system.
The concept and specific operation of the comparator has been described in
the preceding chapter. Here are two setup examples.
