The equivalent circuit mode is
set automatically.
1 to 5 6 to 10 Series equivalent circuit
6 to 10 1 to 5 Parallel equivalent circuit
Therefore it is necessary for the user clearly to understand the setting of this
test mode, in order properly to assess test samples.
In general, parallel equivalent circuit mode should be used for elements
which have relatively low capacitance and high impedance such as film
capacitors and ceramic capacitors, since parallel resistance can cause great
loss in this case; while series equivalent circuit mode should be used for
elements which have relatively high capacitance and low impedance such as
electrolytic capacitors, since series resistance can cause great loss in this
case.
Procedure
Press repeatedly to cycle through available settings: AUTO, SER, and
PAR.
AUTO :
The series equivalent circuit mode or the parallel equivalent circuit
mode is selected automatically according to the following table,
following the measurement range.
SER :
Series equivalent circuit mode
PAR :
Parallel equivalent circuit mode
Use the LED lamp to the left of the key to check on a set equivalent circuit
mode.
